[0095] With reference now to embodiment in more detail, the example of embodiment is shown in the accompanying drawings, wherein the same reference numerals represent the same elements from time to time. In this regard, the present embodiment can have different forms and should not be construed as being limited to the description set forth herein. Therefore, the following only describes the embodiments to explain the various aspects of this specification sheet by reference to the accompanying drawings. As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items. Throughout the disclosure, the expression "at least one of a, b and c" means only a, only b, only c, both a and b, both a and c, both b and c, all of a, b and c or their variations.

[0096] Hereinafter, the present disclosure will be described in more detail by explaining embodiments of the present disclosure with reference to the accompanying drawings. Like reference numerals in the accompanying drawings represent like elements, and redundant explanations thereof will be omitted.

[0097] In the following description, although terms such as "first," "second," etc. may be used to describe various elements, such elements are not necessarily limited to the above terms. The above terms are only used to distinguish one element from another.

[0098] In the following description, expressions used in the singular also include expressions in the plural form unless it has an apparently different meaning in the context.

[0099] In the following description, it will be understood that terms such as “including,” “having,” and “comprising” are intended to indicate that there are disclosed features, quantities, steps, actions, elements, parts, or combinations thereof in the specification, and are not intended to exclude the possibility that one or more other features, quantities, steps, actions, elements, parts, or combinations thereof may exist or may be added.

[0100] Furthermore, when describing embodiments of the present disclosure, the use of “may” refers to “one or more embodiments of the present disclosure.”

[0101] In the following description, it will be understood that when a component such as a layer, film, region, or plate is referred to as being “on” another component, it can be directly on the other component or intervening components may be present therebetween.

[0102] For the convenience of explanation, the sizes of the components in the drawings may be exaggerated. In other words, since the sizes and thicknesses of the components in the drawings are arbitrarily shown for the convenience of explanation, the following embodiments are not limited thereto.

[0103] In the following examples, the x-axis, y-axis, and z-axis are not limited to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other.

[0104] When example embodiments may be implemented differently, the specific process order may be performed differently from the described order. For example, two consecutively described processes may be performed substantially simultaneously or in a reverse order from the described order.

[0105] As used herein, phrases such as "plan view" may refer to a view from the top or from a direction perpendicular to the display area of ​​the display panel.

[0106] For ease of description, spatially relative terms such as "under," "beneath," "down," "above," "up," "bottom," "top," etc. may be used herein to describe the relationship of one element or feature to another (other) element or feature as shown in the accompanying drawings. It will be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, the element described as "under" or "beneath" other elements or features will then be positioned as "above" or "on" the other elements or features. Thus, the term "under" can include both above and below orientations. The device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0107] As used herein, the terms "substantially," "about," and similar terms are used as terms of approximation rather than terms of degree, and are intended to account for the inherent variations in measurements or calculations that those skilled in the art would recognize.

[0108] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will also be understood that terms (such as those defined in common dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and / or the context of this application, and should not be interpreted in an idealized or overly formal sense unless clearly defined herein.

[0109] Figure 1A is a perspective view showing a portion of a vehicle in which the display apparatus 1 is arranged according to one or more embodiments. Figure 1B is a plan view showing a display device 1 according to the embodiment. Figure 1C is a plan view showing a display device 1 according to another embodiment.

[0110] Reference Figures 1A to 1C , the display device 1 may include a display panel 20 (see Figure 2A ). The display panel 20 may include a display area DA on the substrate 21 and a non-display area NDA outside or around the display area DA. In one or more embodiments, the non-display area NDA surrounds the display area DA. The emission portion may be arranged in the display area DA, and the power wiring may be arranged in the non-display area NDA. In one or more embodiments, a pad (or "pad") portion C may be located in the non-display area NDA. In one or more embodiments, the pad portion C may be adjacent to one side of the non-display area NDA.

[0111] In the above case, the display area DA can have various suitable shapes. For example, the display area DA can have a rectangular shape, a square shape, or a circular shape. In one or more embodiments, the display area DA can have an irregular shape other than a rectangle, a square, a polygon, or a circle. However, hereinafter, for ease of description, one or more embodiments in which the display area DA has a rectangular shape will be described in more detail.

[0112] The display device 1 may be arranged inside the vehicle. In this case, the display device 1 may display various suitable types of images, characters, and the like.

[0113] The display device 1 can typically be arranged obliquely on the interior material of the vehicle. In this case, the display device 1 can have various suitable shapes. For example, the outer surface of the display device 1 can be circular. In another embodiment, the display device 1 can have a circular or polygonal shape. For ease of description, one or more embodiments in which the display device 1 has a rectangular shape will be described in more detail below.

[0114] The display device 1 may have a rectangular shape or a square shape. In this case, the display device 1 may have a short side and a long side. Here, the long side of the display device 1 or the short side of the display device 1 may be arranged adjacent to the window WD of the vehicle. In one or more embodiments, the display device 1 is spaced apart from the window WD, and the display area DA of the display device 1 does not face the window WD (i.e., faces away from the window WD).

[0115] In one or more embodiments, Figure 1A As shown in , the long side of the display device 1 can be arranged in one direction of the inner frame of the vehicle. In this case, Figure 1B The long side of the display device 1 may be parallel to the window WD, and the gaze direction of the user viewing from the side of the display device 1 may be a direction perpendicular to the short side of the display device 1 or a direction perpendicular (or perpendicular) to the short side of the display device 1 (or a direction parallel to the long side of the display device 1). Figure 1A The display device 1 may be viewed from the steering wheel H of the vehicle, or may be viewed at one side of the steering wheel H. In one or more embodiments, the user may view the display device 1 from a driver's seat or a passenger seat of the vehicle.

[0116] In one or more embodiments, Figure 1CThe short side of the display device 1 may be parallel to the window WD. In this case, the long side of the display device 1 may be arranged from the upper part to the lower part of the vehicle. In other words, the long side of the display device 1 may be oriented vertically. The gaze direction of the user viewing the display device 1 from the side may be a direction perpendicular to the long side of the display device 1 or a direction perpendicular to the long side of the display device 1 (or a direction parallel to the short side of the display device 1).

[0117] The display device 1 may include a blocking layer 52. The blocking layer 52 may prevent or substantially prevent images, characters, etc. displayed on the display device 1 from being formed or reflected in the window WD. That is, the blocking layer 52 may prevent or substantially prevent light emitted from each sub-pixel of the display device 1 from traveling at a predetermined or set angle relative to the surface of the display device 1.

[0118] When the display device 1 does not include the blocking layer 52, images, characters, etc. may be reflected on the window WD, and therefore, the driver's field of vision may be disturbed. In one or more embodiments, when the display device 1 including the blocking layer 52 is operated, an afterimage or stripes (or wave pattern) may be displayed on the display device 1 due to the operation of the display device 1 or the moire phenomenon caused by external light. In other words, reflection can be prevented or substantially prevented, but there may be a pattern caused by the moire phenomenon. However, in one or more embodiments, the generation of a pattern in the display device 1 can be prevented or substantially prevented by preventing or substantially preventing the above-mentioned moire phenomenon. In this case, as Figure 1B and Figure 1C As shown in FIG, the barrier layers 52 provided as a plurality of barrier layers 52 may be connected in a straight line instead of being spaced apart from each other in a line.

[0119] This will be described in more detail below.

[0121] Reference Figures 2A to 3 , the display device 1 may include a display panel 20 , an optical functional member 30 , an adhesive part 40 , and a barrier part 50 .

[0122] The display panel 20 may have various suitable shapes. For example, the display panel 20 may include a substrate 21, a display D, and an encapsulation portion.

[0123] In this case, the packaging portion may include Figure 2A . The sealing portion SA and the encapsulation substrate EC are shown in FIG. The sealing portion SA can connect the encapsulation substrate EC to the substrate 21 to block or seal the display D from the outside (e.g., the external environment) together with the encapsulation substrate EC. The encapsulation substrate EC can be arranged to face the substrate 21 and can be fixed or bonded to the sealing portion SA. In this case, the encapsulation substrate EC can be the same as or similar to the substrate 21.

[0124] The packaging part may include Figure 2B The thin film encapsulation layer E shown in FIG. The thin film encapsulation layer E may include a plurality of inorganic layers or may include an inorganic layer and an organic layer.

[0125] The organic layer of the thin film encapsulation layer E may be formed of a polymer and may include polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyimide, polyethylene sulfonate, polyoxymethylene, polyarylate, hexamethyldisiloxane, acrylic resin (e.g., polymethyl methacrylate, polyacrylic acid, etc.), or a combination thereof.

[0126] The inorganic layer of the thin film encapsulation layer E may be a single layer or a stacked layer including metal oxide or metal nitride. In more detail, the inorganic layer may include silicon nitride (SiN x ), one of aluminum oxide (Al2O3), silicon dioxide (SiO2) and / or titanium dioxide (TiO2).

[0127] The uppermost or outermost layer of the thin film encapsulation layer E, which is exposed to the outside (eg, external environment), may be formed as an inorganic layer to prevent or substantially prevent moisture from penetrating into the organic light emitting diode.

[0128] In one or more embodiments, the thin film encapsulation layer E may include at least one sandwich structure in which at least one organic layer is between at least two inorganic layers. In one or more embodiments, the thin film encapsulation layer E may include at least one sandwich structure in which at least one inorganic layer is between at least two organic layers. In one or more embodiments, the thin film encapsulation layer E may include a sandwich structure in which at least one organic layer is between at least two inorganic layers and a sandwich structure in which at least one inorganic layer is between at least two organic layers.

[0129] For example, the thin film encapsulation layer E may include a first inorganic layer, a first organic layer, and a second inorganic layer in sequence from above the organic light emitting diode 28 .

[0130] As another example, the thin film encapsulation layer E may include a first inorganic layer, a first organic layer, a second inorganic layer, a second organic layer, and a third inorganic layer in sequence from above the organic light emitting diode 28 .

[0132] In one or more embodiments, the display device 1 may include a protective layer between the organic light emitting diode 28 and the first inorganic layer. The protective layer may further include a metal halide layer containing lithium fluoride (LiF). When the first inorganic layer is formed using a sputtering method, the metal halide layer may prevent or substantially prevent the organic light emitting diode 28 from being damaged.

[0133] An area of ​​the first organic layer may be smaller than an area of ​​the second inorganic layer, and an area of ​​the second organic layer may be smaller than an area of ​​the third inorganic layer.

[0134] In the case where the inorganic layer is provided as a plurality of inorganic layers, the inorganic layers may be deposited to directly contact each other in the edge region of the display panel 20 and prevent or substantially prevent the organic layer from being exposed to the outside (eg, external environment).

[0135] In one or more embodiments, the display panel 20 may include a touch layer. The touch layer may be in the form of a film and disposed between the encapsulation portion and the display D or on the upper surface of the encapsulation portion. In this case, the touch layer may be formed separately to be attached or bonded to the encapsulation portion or may be formed directly on the encapsulation portion in a patterned form.

[0136] The display D may include a thin film transistor (TFT), a passivation layer 27 , and an organic light emitting diode 28 .

[0137] The substrate 21 may be formed of a plastic material and / or a metal material such as stainless steel (SUS) and / or titanium (Ti). The substrate 21 may include a polymer resin such as polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, and / or cellulose acetate propionate. The substrate 21 may have a single layer or multilayer structure of the above materials, and when the substrate 21 has a multilayer structure, it may further include an inorganic layer. Hereinafter, for ease of description, one or more embodiments in which the substrate 21 is formed of polyimide will be described in more detail.

[0138] A TFT may be formed on the substrate 21 , a passivation layer 27 may be formed to cover the TFT, and an organic light emitting diode 28 may be formed on the passivation layer 27 .

[0139] A buffer layer 22 is further formed on the upper surface of the substrate 21. The buffer layer 22 is composed of organic compounds and / or inorganic compounds. The inorganic compound may include SiO x(where x≥1) and / or SiN x (where x≥1).

[0140] Active layer 23 is formed on buffer layer 22 in a predetermined or set pattern and then buried by gate insulating layer 24. Active layer 23 includes source region 23-1, drain region 23-3, and channel region 23-2 between source region 23-1 and drain region 23-3.

[0141] The active layer 23 may include various suitable materials. For example, the active layer 23 may include an inorganic semiconductor material such as amorphous silicon or crystalline silicon. In one or more embodiments, the active layer 23 may include an oxide semiconductor. In one or more embodiments, the active layer 23 may include an organic semiconductor material. However, for ease of description, one or more embodiments in which the active layer 23 includes crystalline silicon will be described in more detail below.

[0142] The active layer 23 may be formed by forming an amorphous silicon layer on the buffer layer 22, crystallizing the amorphous silicon layer into a polysilicon layer, and patterning the polysilicon layer. The source region 23-1 and the drain region 23-3 of the active layer 23 may be doped with impurities according to the type of TFTs such as driving TFTs and switching TFTs.

[0143] On an upper surface of the gate insulating layer 24 , a gate electrode 25 corresponding to the active layer 23 and an interlayer insulating layer 26 burying the gate electrode 25 may be formed.

[0144] In one or more embodiments, a contact hole (e.g., contact hole H1) is formed in or through the interlayer insulating layer 26 and the gate insulating layer 24, and then a source electrode 27-1 and a drain electrode 27-2 are formed on the interlayer insulating layer 26 to contact the source region 23-1 and the drain region 23-3, respectively, through the contact hole. In one or more embodiments, the source electrode 27-1 and the drain electrode 27-2 fill the corresponding contact holes formed in or through the interlayer insulating layer 26 and the gate insulating layer 24.

[0145] A passivation layer 27 is formed on the TFT, and a pixel electrode 28-1 of the organic light emitting diode 28 is formed on the passivation layer 27. The pixel electrode 28-1 contacts the drain electrode 27-2 of the TFT through a through hole H2 formed in the passivation layer 27. The passivation layer 27 may include an inorganic material and / or an organic material, and may include a single layer or two or more layers. The passivation layer 27 may be formed as a planarization layer having a flat top surface, regardless of the curvature of the layer below it (e.g., regardless of the shape of the layer below the passivation layer 27), or may be formed to bend along the curvature of the layer below it (e.g., bend along the shape of the layer below the passivation layer 27). In other words, the upper surface of the passivation layer 27 may be flat, or may correspond to the shape of the layer below the passivation layer 27. In one or more embodiments, the passivation layer 27 includes a transparent insulator to achieve a resonance effect.

[0146] After forming the pixel electrode 28-1 on the passivation layer 27, a pixel defining layer 29 is formed of an organic material and / or an inorganic material to cover the pixel electrode 28-1 and the passivation layer 27. A portion of the pixel defining layer 29 is opened to expose the pixel electrode 28-1. In other words, the pixel defining layer 29 may define an opening that exposes the top surface of the pixel electrode 28-1.

[0147] Here, the spacer P can be positioned on the pixel defining layer 29. The spacer P can be arranged on the pixel defining layer 29 or can be formed integrally with the pixel defining layer 29. The spacer P can have various suitable shapes. For example, the spacer P can be formed in a protrusion shape. In one or more embodiments, the spacer P can be provided as a plurality of spacers P, and the spacers P can be arranged on the pixel defining layer 29 to be spaced apart from each other. In another embodiment, one spacer P can be provided in the space between adjacent sub-pixels (or between adjacent intermediate layers). However, the spacer P is not limited thereto, and when each mask sheet enters the opening of the pixel defining layer 29 or the deposition material is deposited on the substrate 21, each mask sheet is tightly attached or bonded to the pixel defining layer 29 to contact the substrate 21, thereby preventing or substantially preventing a dent defect that damages or destroys a portion of the substrate 21. Specifically, when each mask assembly is tightly attached or bonded to the substrate 21, the spacer P can maintain the distance between the end of the opening of the pixel defining layer 29 and each mask assembly. Therefore, the spacer P may be arranged so as not to overlap with each intermediate layer.

[0148] The spacer P may be formed as an integral or one-piece structure concurrently (e.g., simultaneously) with the pixel defining layer 29 when the pixel defining layer 29 is formed, or may be formed separately on the pixel defining layer 29 after the pixel defining layer 29 is formed. Therefore, the spacer P may be formed of the same material as or a different material from that of the pixel defining layer 29. Hereinafter, for ease of description, one or more embodiments in which the spacer P is formed of the same material as that of the pixel defining layer 29 will be described in more detail.

[0149] In one or more embodiments, the intermediate layer 28-2 and the counter electrode 28-3 are formed on at least the pixel electrode 28-1. In another embodiment, the counter electrode 28-3 may be formed on the front surface of the substrate 21. In this case, the counter electrode 28-3 may be formed on the intermediate layer 28-2 and the pixel-defining layer 29. Hereinafter, for ease of description, one or more embodiments in which the counter electrode 28-3 is formed on the intermediate layer 28-2 and the pixel-defining layer 29 will be described in more detail.

[0150] The pixel electrode 28 - 1 functions as an anode electrode, and the counter electrode 28 - 3 functions as a cathode electrode, but the polarities of the pixel electrode 28 - 1 and the counter electrode 28 - 3 may be opposite.

[0151] The pixel electrode 28 - 1 and the counter electrode 28 - 3 are insulated from each other by the intermediate layer 28 - 2 , and voltages of opposite polarities are applied to the intermediate layer 28 - 2 to induce light emission in the organic emission layer.

[0152] The intermediate layer 28-2 may include an organic emission layer. Optionally, the intermediate layer 28-2 may include an organic emission layer and may further include at least one of a hole injection layer (HIL), a hole transport layer, an electron transport layer, and an electron injection layer. However, the present embodiment is not limited thereto, and the intermediate layer 28-2 may include an organic emission layer and may further include various suitable functional layers.

[0153] The intermediate layer 28 - 2 may be provided as a plurality of intermediate layers 28 - 2 , and the plurality of intermediate layers 28 - 2 may form the display area DA. In this case, the plurality of intermediate layers 28 - 2 may be arranged in the display area DA to be spaced apart from each other.

[0154] A unit pixel may include multiple sub-pixels. Multiple sub-pixels can emit light beams of various suitable colors. In one or more embodiments, a sub-pixel may refer to an area that emits light of one color. In another embodiment, a sub-pixel may be defined as a portion of the pixel electrode 28-1 that is exposed to the outside through an opening area of ​​the pixel defining layer 29. In one or more embodiments, the opening area of ​​the pixel defining layer 29 corresponds to the bottom of the opening of the pixel defining layer 29, which extends through the pixel defining layer 29 to expose a portion of the pixel electrode 28-1. In this case, the area of ​​the pixel electrode 28-1 exposed to the outside can be adjusted by adjusting the size of the opening area of ​​the pixel defining layer 29 to thereby control the size of a sub-pixel. In other words, adjusting the size of a sub-pixel can be achieved by adjusting the size of the opening extending through the pixel defining layer 29. However, hereinafter, for ease of description, one or more embodiments in which a sub-pixel is an area that emits a light beam of one color will be described in more detail.

[0155] The plurality of sub-pixels may include sub-pixels that emit red light, green light, and blue light, respectively. In another embodiment, the plurality of sub-pixels may include sub-pixels that emit red light, green light, blue light, and white light. In another embodiment, the plurality of sub-pixels may include sub-pixels that emit red light, yellow light, and blue light. However, the plurality of sub-pixels are not limited thereto, and the present disclosure may include all suitable variations of the case where sub-pixels emit light beams of different colors. However, hereinafter, for ease of description, one or more embodiments in which the plurality of sub-pixels include sub-pixels that emit blue light, red light, and green light will be described in more detail.

[0156] The apparatus for manufacturing a display device, which will be described later, can form various suitable layers on the substrate 21. For example, the apparatus for manufacturing a display device can form at least one of the intermediate layers 28-2 on the substrate 21. In more detail, the apparatus for manufacturing a display device can form at least one of the organic emission layer, the HIL, the hole transport layer, the electron injection layer, the electron transport layer, and the functional layer of the intermediate layer 28-2. Specifically, when the apparatus for manufacturing a display device forms at least one layer of the intermediate layer 28-2 on the substrate 21, the apparatus for manufacturing a display device can manufacture one layer using a plurality of deposition materials or manufacture a plurality of layers concurrently (e.g., simultaneously).

[0157] In one or more embodiments, the optical functional member 30 may be between the display D and the barrier 50. The optical functional member 30 may include a phase retarder and a polarizer. The phase retarder may be of a film type or a liquid crystal coating type, and may include a λ / 2 phase retarder and / or a λ / 4 phase retarder. The polarizer may also be of a film type or a liquid crystal coating type. The film type may include a stretchable synthetic resin film, and the liquid crystal coating type may include liquid crystals arranged in a predetermined or set orientation.

[0158] In another embodiment, the optical functional member 30 may include a black matrix and a color filter. The color filters may be arranged based on the color of the light emitted by the pixels of the display device 1. Each color filter may include a red, green, or blue pigment or dye. Optionally, in addition to the above-mentioned pigments or dyes, each color filter may also include quantum dots. Optionally, some of the color filters may not include the above-mentioned pigments or dyes, and may include scattering particles such as titanium oxide.

[0159] In another embodiment, the optical function member 30 may include a destructive interference structure. The destructive interference structure may include a first reflective layer and a second reflective layer arranged on different layers. The first reflected light and the second reflected light reflected by the first reflective layer and the second reflective layer, respectively, may destructively interfere with each other, thereby reducing the reflectivity of external light.

[0160] The adhesive part 40 may connect the optical functional member 30 to the barrier part 50. In this case, the adhesive part 40 may include an optically clear adhesive (OCA).

[0161] The barrier 50 may include a base layer 51, a barrier layer 52, and a protective layer 53. The base layer 51 may include a transparent resin for nano-implantation, such as polyethylene methyl methacrylate, a light-curable resin, or the like.

[0162] The barrier layer 52 may be inserted into the base layer 51. The barrier layer 52 may be made of an opaque material to block external light and / or light from the display panel 20 from being transmitted to the outside (e.g., the external environment). Specifically, the barrier layer 52 is provided as a plurality of barrier layers 52 and is arranged to be spaced apart from each other, thereby preventing or substantially preventing light from the display area DA from moving to a plane formed by the display area DA. Figure 1B and Figure 1CThe barrier layer 52 may be formed in the form of ink and may be formed by being inserted into the groove of the base layer 51 and solidified. In this case, the end of the barrier layer 52 adjacent to the outer surface of the base layer 51 among the ends of the barrier layer 52 may be concave. That is, the end of the barrier layer 52 may be recessed into the base layer 51. In this case, a portion of the adhesive portion 40 may be inserted into the recess of the barrier layer 52. A portion of the adhesive portion 40 may have a convex shape. When the display device 1 is formed in a rectangular shape, the length direction of the barrier layer 52 (for example, Figure 2A and Figure 2B The Y-axis direction) may be parallel to one side of the display device 1 or may have a predetermined or set angle (e.g., see Figure 2A and Figure 2B ).

[0163] The protective layer 53 may be disposed on the outer surfaces of the barrier layer 52 and the base layer 51 to protect the barrier layer 52 and the display panel 20 from external impact. In other words, the protective layer 53 forms the outermost surface of the display device 1. In this case, the protective layer 53 may include polycarbonate.

[0164] Figure 4A is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments. Figure 4B It shows Figure 4A FIG. 1 is a plan view of the arrangement of the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 and the barrier layer 52 shown in FIG.

[0165] Reference Figure 4A and Figure 4B, the plurality of sub-pixels may include a first sub-pixel F1, a second sub-pixel F2, and a third sub-pixel F3. The first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may have a rectangular shape or a substantially rectangular shape. In this case, one of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may have a rectangular shape, a square shape, or a diamond shape with four sides being the same or substantially the same, and the other two of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may have a rectangular shape with each pair of sides (e.g., sides opposite to each other) being the same or substantially the same. For example, one of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may have a substantially square shape or a diamond shape, and the other two of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may have a substantially rectangular shape. In this case, the substantially square (or diamond) shape may refer to a rectangle in which, based on one of the sides of the square, the remaining sides of all sides have lengths that are within a certain error margin from the length of the one side. In addition, a roughly rectangular shape may refer to a rectangle in which one side of a pair of sides facing each other (e.g., opposite) has a length within a certain margin of error based on the length of the other side of the pair of sides facing each other (e.g., opposite). Specifically, the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 formed by the deposition process described below may be formed into a roughly square shape or a rectangular shape as described above. In this case, the first sub-pixel F1, the second sub-pixel F2, or the third sub-pixel F3 may have a roughly square (diamond) shape or a rectangular shape in which the edge portion is rounded or chamfered. In one or more embodiments, the angle of each edge (or vertex) formed between the connecting edges of each of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may not be equal to 90° at all edges (or vertices), and may also be within a certain margin of error.

[0166] Hereinafter, for ease of description, one or more embodiments in which the first subpixel F1 has a square shape and the second and third subpixels F2 and F3 have rectangular shapes will be described in more detail. As used herein, the square and rectangle described below may refer to the substantially square shape and substantially rectangular shape, respectively, as described above.

[0167] One of the first, second, and third subpixels F1, F2, and F3 emits blue light, another of the first, second, and third subpixels F1, F2, and F3 emits red light, and yet another of the first, second, and third subpixels F1, F2, and F3 emits green light. In this case, depending on the shape of each of the first, second, and third subpixels F1, F2, and F3, one of the blue, red, and green lights may have a square shape, and the other of the blue, red, and green lights may have a rectangular shape. Below, for ease of description, one or more embodiments in which the first subpixel F1 emits blue light, the second subpixel F2 emits red light, and the third subpixel F3 emits green light will be described in more detail. However, embodiments of the present disclosure are not limited thereto, and the first subpixel F1 may emit green light.

[0168] The regions (areas) of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 can be variously configured in a suitable manner. In this case, because the aperture ratio of each sub-pixel is adjustable, a display panel having various suitable shapes and capable of performing various suitable operations can be realized.

[0169] The first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may include a first intermediate layer 28-2A, a second intermediate layer 28-2B, and a third intermediate layer 28-2C, respectively. In one or more embodiments, the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may include materials (e.g., organic light-emitting layers) that emit different light beams when external power is applied thereto. In other words, the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may include different materials (e.g., organic emission layers) that emit different light beams (e.g., light beams of different colors) in response to power supplied to each intermediate layer.

[0170] The first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may correspond to the shapes of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, respectively. For example, the first intermediate layer 28-2A may have a square shape to correspond to the square shape of the first sub-pixel F1. In one or more embodiments, the second intermediate layer 28-2B and the third intermediate layer 28-2C may have a rectangular shape to correspond to the rectangular shapes of the second sub-pixel F2 and the third sub-pixel F3, respectively. In this case, the plane area (or plane area) of each intermediate layer may be the same as or different from the plane area of ​​each sub-pixel. For example, in one or more embodiments, the plane area of ​​the first intermediate layer 28-2A may be different from the plane area of ​​the first sub-pixel F1, the plane area of ​​the second intermediate layer 28-2B may be the same as the plane area of ​​the second sub-pixel F2, and the plane area of ​​the third intermediate layer 28-2C may be the same as the plane area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2, the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1, and the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, and the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1. In another embodiment, the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, and the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, and the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2. In another embodiment, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3.In another embodiment, the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3. In one or more embodiments, the planar area may refer to the area of ​​the plane formed by the display area of ​​the display device. Alternatively, the planar area may refer to the area of ​​the plane on which the image is realized when the image is realized. Hereinafter, for ease of description, one or more embodiments in which the planar area of ​​each intermediate layer is different from the planar area of ​​each sub-pixel will be described in more detail.

[0171] In one or more embodiments, Figure 4A and Figure 4B As shown in , the planar area of ​​each sub-pixel can be smaller than the planar area of ​​each intermediate layer. In one or more embodiments, each intermediate layer can be deposited on the substrate 21 to have a sufficient margin relative to each sub-pixel, so that light with a precise shape can be emitted from each sub-pixel.

[0172] Hereinafter, for convenience of description, since the relationship between sub-pixels and the relationship between intermediate layers are the same as or similar to each other, the relationship between sub-pixels will be described in more detail.

[0173] The first sub-pixels F1, the second sub-pixels F2, and the third sub-pixels F3 may be provided as a plurality of first sub-pixels F1, a plurality of second sub-pixels F2, and a plurality of third sub-pixels F3, respectively. The first sub-pixels F1 may be spaced apart from each other in at least one of the first direction and the second direction. For example, some of the first sub-pixels F1 may be arranged in a first direction (e.g., Figure 4A , and the other first sub-pixels F1 in the first sub-pixels F1 may be arranged in a second direction (eg, Figure 4A In the following, for the convenience of description, the first direction will be described in more detail. Figure 4A The X-axis direction, and the second direction refers to Figure 4A One or more embodiments of the Y-axis direction.

[0174] The centers of the first sub-pixels F1 arranged in the first direction among the first sub-pixels F1 may be arranged in a straight line. In this case, the first sub-pixels F1 arranged in the first direction among the first sub-pixels F1 may be arranged in a row (or a straight line) in the first direction. Here, the first direction may be parallel to the long side of the display panel 20. In this case, in one or more embodiments, the first sub-pixels F1 may emit green light with high visibility. Specifically, when the first sub-pixels F1 emit green light, the visibility of the characters in the image implemented in the display panel 20 (or provided by the display panel 20) may be improved. In one or more embodiments, the centers of the first sub-pixels F1 arranged in the second direction among the first sub-pixels F1 may not be arranged in a straight line, but may be arranged in a serpentine (or zigzag) form (for example, as shown in FIG. 1 ). Figure 4A shown).

[0175] The predetermined or set angle may be between the first side S1 and the second side S2 of each first sub-pixel F1. Specifically, the first side S1 and the second side S2 of the first sub-pixel F1 may be perpendicular to each other. In this case, the first side S1 and the second side S2 may be inclined in different directions relative to at least one of the first direction and the second direction. Therefore, each first sub-pixel F1 may be arranged in a diamond shape based on one of the first direction and the second direction, and the angle formed between the two sides (for example, the first side S1 and the second side S2) adjacent to each vertex of each first sub-pixel F1 may be 90°. Specifically, each first sub-pixel F1 may have a square (or diamond) shape.

[0176] In this case, a second sub-pixel F2 and a third sub-pixel F3 can be arranged to face the first sub-pixel F1 at the first side S1 or the second side S2 of the first sub-pixel F1. The second sub-pixel F2 and the third sub-pixel F3 can be tilted relative to one of the first direction and the second direction. Specifically, the second sub-pixel F2 and the third sub-pixel F3 can be tilted so as to form an angle of 45° or approximately 45° relative to one of the first direction and / or the second direction. For example, an angle of 45° or approximately 45° can be formed between at least one of the short side and the long side of at least one of the second sub-pixel F2 and the third sub-pixel F3 and a straight line connecting or passing through the center of the first sub-pixel F1 arranged in the first direction. In one or more embodiments, a side of the second sub-pixel F2 and a side of the third sub-pixel F3 can be parallel to a side of the first sub-pixel F1.

[0177] The second subpixel F2 and the third subpixel F3 may each have a rectangular shape. Here, the area of ​​at least one of the second subpixel F2 and the third subpixel F3 may be smaller than the area of ​​the first subpixel F1. In one or more embodiments, at least one of the second subpixel F2 and the third subpixel F3 facing the first subpixel F1 may be arranged to overlap with a side (e.g., the first side S1 or the second side S2) of the first subpixel F1 facing the second subpixel F2 and the third subpixel F3 (in a direction parallel to the plane defined by the X-axis and the Y-axis), and / or may be arranged to overlap with an extension line of the side of the first subpixel F1 (in a direction parallel to the plane defined by the X-axis and the Y-axis). For example, at least a side of the second subpixel F2 and at least a side of the third subpixel F3 adjacent to the second subpixel F2 may be arranged within the length range of one of the first side S1 and the second side S2. The short side of the second subpixel F2 or the short side of the third subpixel F3 may be arranged as a straight line extending from a side of the other first subpixel F1.

[0178] At least one of the second subpixel F2 and the third subpixel F3 facing the first subpixel F1 may have a short side or a long side parallel to the first side S1 or the second side S2. In one or more embodiments, the extension lines of the short sides of different second subpixels F2 facing the first side S1 and the second side S2, respectively, may intersect with each other, or the extension lines of the long sides of different second subpixels F2 facing the first side S1 and the second side S2, respectively, may intersect with each other. In another embodiment, the extension lines of the short sides of the third subpixel F3 facing the first side S1 and the second side S2, respectively, may intersect with each other, or the extension lines of the long sides of the third subpixel F3 facing the first side S1 and the second side S2, respectively, may intersect with each other. In another embodiment, the extension line of the short side of the second subpixel F2 facing the first side S1 may intersect with the extension line of the short side of the third subpixel F3 facing the second side S2, or the extension line of the long side of the second subpixel F2 facing the first side S1 may intersect with the extension line of the long side of the third subpixel F3 facing the second side S2. In another embodiment, the extension line of the long side of the second sub-pixel F2 facing the first side S1 may intersect with the extension line of the short side of the third sub-pixel F3 facing the second side S2, or the extension line of the short side of the second sub-pixel F2 facing the first side S1 may intersect with the extension line of the long side of the third sub-pixel F3 facing the second side S2.

[0179] The second sub-pixels F2 may be arranged to be spaced apart from each other in at least one of the first and second directions. In this case, the centers of some of the second sub-pixels F2 arranged in one of the first and second directions may be arranged in a straight line, and the centers of other second sub-pixels F2 arranged in the other of the first and second directions may be arranged in a serpentine (or zigzag) form in the other of the first and second directions. Hereinafter, for ease of description, one or more embodiments in which the centers of some of the second sub-pixels F2 arranged in the first direction are arranged in a straight line, and the centers of other second sub-pixels F2 arranged in the second direction are arranged in a serpentine form will be described in more detail.

[0180] Similar to the second sub-pixels F2, the third sub-pixels F3 may be arranged to be spaced apart from each other in at least one of the first and second directions. In this case, the third sub-pixels F3 may be arranged in a manner similar to the second sub-pixels F2. Hereinafter, for ease of description, one or more embodiments will be described in more detail in which the centers of some of the third sub-pixels F3 arranged in the first direction are arranged in a straight line, while the centers of other third sub-pixels F3 arranged in the second direction are arranged in a serpentine form.

[0181] In the above case, one of the second subpixel F2 and the third subpixel F3 facing the first side S1 of the first subpixel F1 can be arranged symmetrically with one of the second subpixel F2 and the third subpixel F3 facing the second side S2 of the first subpixel F1 relative to or about a straight line connecting or passing through the center of the first subpixel F1 arranged in the first direction (or a straight line passing through the centers of two adjacent subpixels and parallel to the first direction). For example, in one or more embodiments, the second subpixel F2 facing the first side S1 can be symmetrical with the third subpixel F3 facing the second side S2 relative to or about the straight line. In one or more embodiments, the third subpixel F3 facing the first side S1 can be symmetrical with the second subpixel F2 facing the second side S2 relative to or about the straight line. In this case, the distance between the centers of the adjacent second subpixels F2 can be the same as the distance between the centers of the adjacent third subpixels F3. In another embodiment, the second subpixel F2 and the third subpixel F3 facing the first side S1 can be symmetrical with the second subpixel F2 and the third subpixel F3 facing the second side S2 relative to or about the straight line. In this case, the distance between the centers of one of the pair of second subpixels F2 and the pair of third subpixels F3 arranged symmetrically with each other can be smaller than the distance between the centers of the other of the pair of second subpixels F2 and the pair of third subpixels F3 arranged symmetrically with each other. In this case, the pair of second subpixels F2 adjacent to each other can be positioned between the pair of third subpixels F3 adjacent to each other, or the pair of third subpixels F3 adjacent to each other can be positioned between the pair of second subpixels F2 adjacent to each other. However, hereinafter, for ease of description, one or more embodiments in which the second subpixels F2 and the third subpixels F3 are arranged symmetrically with respect to or about a straight line connecting or passing through the centers of the first subpixels F1 arranged in the first direction will be described in more detail.

[0182] The size of the second subpixel F2 may be the same as the size of the third subpixel F3. For example, the planar area of ​​the second subpixel F2 may be the same as the planar area of ​​the third subpixel F3. In this case, the size of the short side of the second subpixel F2 may be the same as the size of the short side of the third subpixel F3, and the size of the long side of the second subpixel F2 may be the same as the size of the long side of the third subpixel F3. Here, the second intermediate layer 28-2B and the third intermediate layer 28-2C arranged in the second subpixel F2 and the third subpixel F3, respectively, may also have substantially the same size as the second subpixel F2 and the third subpixel F3.

[0183] The shortest distance from one of the two subpixels facing an edge of the first subpixel F1 to the edge of the first subpixel F1 may be different from the shortest distance from the other of the two subpixels to the edge of the first subpixel F1. For example, a first distance L1, which is the shortest distance from the edge of the first subpixel F1 to the second subpixel F2, may be different from a second distance L2, which is the shortest distance from the edge of the first subpixel F1 to the third subpixel F3. Specifically, the first distance L1 may be smaller than the second distance L2. In this case, the shortest distance from the first side S1 or the second side S2 to an edge of the second subpixel F2 or an edge of the third subpixel F3 may be measured in a direction perpendicular to or perpendicular to one of the first side S1 and the second side S2. In another embodiment, the shortest distance can be measured from the first side S1 (or the extension of the first side S1) or the second side S2 (or the extension of the second side S2) to a side of the second subpixel F2 or a side of the third subpixel F3 in a direction perpendicular to the extension line of one of the first side S1 and the second side S2 or in a direction perpendicular to the extension line of one of the first side S1 and the second side S2. However, hereinafter, for ease of description, one or more embodiments in which the shortest distance is the distance measured between the first side S1 or the extension line of the first side S1 and the second subpixel F2 and the third subpixel F3 facing the first side S1 will be described in more detail. In another embodiment, the shortest distance can be measured as the distance from the center of the first subpixel F1 to the center of the second subpixel F2 or the distance from the center of the first subpixel F1 to the center of the third subpixel F3. In another embodiment, the shortest distance may be measured as the distance from the first side S1 of the first subpixel F1 or the extension line of the first side S1 to the center of the second subpixel F2 or the distance from the first side S1 of the first subpixel F1 or the extension line of the first side S1 to the center of the third subpixel F3.

[0184] In one or more embodiments, the distance from the edge of one of the second subpixel F2 and the third subpixel F3 facing the same first subpixel F1 to the edge of the first subpixel F1 may be different from the distance from the edge of the other of the second subpixel F2 and the third subpixel F3 to the edge of the first subpixel F1. For example, a first distance L1 from the short side of the second subpixel F2 facing the first side S1 to the first side S1 may be different from a third distance L3 from the short side of the second subpixel F2 facing the second side S2 to the second side S2. Furthermore, a second distance L2 from the short side of the third subpixel F3 facing the first side S1 to the first side S1 may be different from a fourth distance L4 from the short side of the third subpixel F3 facing the second side S2 to the second side S2. Here, the third distance L3 may be equal to or substantially equal to the second distance L2, and the fourth distance L4 may be equal to or substantially equal to the first distance L1.

[0185] In one or more embodiments, the shortest distance from the edge of one of the second subpixel F2 and the third subpixel F3, which are arranged between adjacent first subpixels F1, to the edge of one first subpixel F1 may be different from the shortest distance from the edge of the one of the second subpixel F2 and the third subpixel F3 to the edge of the other first subpixel F1. For example, a first distance L1 from the short side of the second subpixel F2 facing the first side S1 of the first subpixel F1 to the first side S1 may be different from a sixth distance L6 from the short side of the second subpixel F2 facing one side of the other adjacent first subpixel F1 to the one side of the other adjacent first subpixel F1. Furthermore, a second distance L2 from the short side of the third subpixel F3 facing the first side S1 of the first subpixel F1 to the first side S1 may be different from a fifth distance L5 from the short side of the third subpixel F3 facing one side of the other adjacent first subpixel F1 to the one side of the other adjacent first subpixel F1. Here, the above relationship may be equally applied to the long side of the second subpixel F2 and the long side of the third subpixel F3, and may also be equally applied to the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C.

[0186] In the above case, the seventh distance L7 from one side of the first subpixel F1 facing each other to the long side of the second subpixel F2, the eighth distance L8 between the long side of the second subpixel F2 and the long side of the third subpixel F3 facing each other, and the ninth distance L9 from the long side of the third subpixel F3 facing each other to one side of the first subpixel F1 can be the same. Here, the seventh distance L7 to the ninth distance L9 can be greater than or equal to the first distance L1 and can be less than the second distance L2. Specifically, such distances provide the width of the mask sheet portion arranged between the openings of the mask sheet to be described below, and therefore, the rigidity of the mask sheet can be maintained. In one or more embodiments, such distances can prevent or substantially prevent the intermediate layers from overlapping or connecting with each other.

[0187] An outline R connecting a portion of an edge of the second subpixel F2 to a portion of an edge of the third subpixel F3 may have a square shape, with the second subpixel F2 and the third subpixel F3 facing one edge of the first subpixel F1. For example, the outline R may be drawn by connecting the remaining edges of the second subpixel F2, except for one edge of the second subpixel F2 and one edge of the third subpixel F3, to the remaining edges of the third subpixel F3 at a portion where the second subpixel F2 and the third subpixel F3 are spaced apart from each other, and connecting a vertex of the second subpixel F2 to a vertex of the third subpixel F3, wherein the one edge of the second subpixel F2 and the one edge of the third subpixel F3 face each other, and the vertex of the second subpixel F2 and the vertex of the third subpixel F3 face each other. The profile R may be formed in a square shape such that the second subpixel F2 and the third subpixel F3 arranged at the first side S1 are arranged by rotating the second subpixel F2 and the third subpixel F3 arranged at the second side S2, and therefore, the arrangement of the second subpixel F2 and the third subpixel F3 arranged at the second side S2 corresponds to the arrangement of the second subpixel F2 and the third subpixel F3 facing the first side S1.

[0188] The first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C, which respectively form the first subpixel F1, the second subpixel F2, and the third subpixel F3, can be formed and arranged in the same or similar manner as the first subpixel F1, the second subpixel F2, and the third subpixel F3, respectively. In this case, the centers of the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C can be arranged at the same or different positions as the centers of the first subpixel F1, the second subpixel F2, and the third subpixel F3, respectively. Here, the above description of the first subpixel F1, the second subpixel F2, and the third subpixel F3 can be applied to the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C, respectively.

[0189] The spacer P may be arranged in at least one of a space between the first subpixel F1 and the second subpixel F2 and a space between the first subpixel F1 and the third subpixel F3. Hereinafter, for ease of description, one or more embodiments in which the spacer P is arranged between a first side S1 and the third subpixel F3 and between a second side S2 and the second subpixel F2 will be described in more detail.

[0190] The distances from the sub-pixels facing the edge of the spacer P to the edge of the spacer P may be the same. For example, a tenth distance L10 from one side of the first sub-pixel F1 facing the edge of the spacer P to the edge of the spacer P, an eleventh distance L11 from the short side of the second sub-pixel F2 facing the edge of the spacer P to the edge of the spacer P, and a twelfth distance L12 from the short side of the third sub-pixel F3 facing the edge of the spacer P to the edge of the spacer P may be the same.

[0191] The barrier layer 52 may be disposed on at least one of the first subpixel F1, the second subpixel F2, and the third subpixel F3. In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52, and the barrier layers 52 may be disposed to be spaced apart from each other.

[0192] In a plan view, each barrier layer 52 may be arranged to intersect a center line CL where the centers of some first sub-pixels F1 are arranged. In this case, in a plan view, at least one of the barrier layers 52 may overlap two sides of at least one of the first sub-pixels F1. For example, Figure 4B In a plan view, one of the barrier layers 52 may overlap the first side S1 and the second side S2 of the first sub-pixel F1.

[0193] The center line CL may be arranged in the first direction. In this case, in a plan view, a second angle θ2 may be formed between the center line CL and the barrier layer 52. The second angle θ2 may be a right angle.

[0194] The length direction of the barrier layer 52 may be parallel to one of the long side and the short side of the substrate 21. Figure 1B When the display device 1 is arranged as shown in FIG, the length direction of the barrier layer 52 may be parallel to the direction of the long side of the substrate 21. In one or more embodiments, when the display device 1 is arranged as shown in FIG. Figure 1C When the display device 1 is arranged as shown in FIG, the length direction of the barrier layer 52 can be parallel to the direction of the short side of the substrate 21. In other words, the length direction of the barrier layer 52 can be parallel to one surface of a window arranged in a vehicle. In addition, the length direction of the barrier layer 52 can be the same as the gaze direction of a user sitting in the width direction of the display device.

[0195] A predetermined or set angle may be formed between the length direction of the barrier layer 52 and one side of at least one of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3. Hereinafter, for ease of description, one or more embodiments of forming an angle between the length direction of the barrier layer 52 and one side of the first sub-pixel F1 will be described in more detail.

[0196] A first angle θ1 may be formed between the length direction of the barrier layer 52 and one side of the first subpixel F1. In this case, the first angle θ1 may be in a range of about 5° to about 85°. Specifically, when the first angle θ1 is less than 5° or greater than 85°, a moiré phenomenon visible in the display device due to the barrier layer 52 may not be eliminated.

[0197] The display panel 20 may be fixed to a device that transports a user, such as a vehicle, an airplane, or the like. In this case, the display device may be fixed to the device so that a predetermined or set angle other than 0° is formed between the user's gaze direction and the first direction or the second direction. For example, the display panel 20 may be arranged so that a 90° angle is formed between the user's gaze direction and the first direction or the second direction. In this case, as described above, each sub-pixel may be fixed relative to the user's gaze direction (e.g., Figure 4B The display panel 20 may be tilted in the Y-axis direction (in the Y-axis direction). For example, one side of each sub-pixel may be tilted relative to the first direction or the second direction. In this case, one side of each sub-pixel may be tilted relative to one of the barrier layer 52, the center line CL, the long side of the display device, and the short side of the display device. Hereinafter, for ease of description, one or more embodiments in which a 90° angle is formed between the gaze direction of a user viewing the display panel 20 and the first direction will be described in more detail.

[0198] In the above case, when the user views the display panel 20, the inclined portion of the pixel defining layer 29 and the gaze direction are not perpendicular or perpendicular to each other, and therefore, external light can be reflected by the inclined portion of the pixel defining layer 29 and prevented or substantially prevented from entering the user's eyes. In other words, the inclined portion of the pixel defining layer 29 can prevent or substantially prevent external light from being reflected into the user's eyes.

[0199] Thus, the display device can reduce glare for the user caused by external light. In one or more embodiments, the display device can remove moire caused by external light through the blocking layer 52. During operation, the display device can prevent or substantially prevent images, characters, etc. from being formed or reflected in the window of the vehicle.

In one or more embodiments, the device 100 for manufacturing a display device may be formed so that the above-mentioned devices are connected to each other in series. In another embodiment, the device 100 for manufacturing a display device may be formed so that only some of the above-mentioned devices are arranged in series, and the other devices are arranged to be spaced apart from the devices arranged in series. In another embodiment, the device 100 for manufacturing a display device may be formed so that each device is arranged separately. However, hereinafter, for the sake of convenience of description, one or more embodiments in which the device 100 for manufacturing a display device includes a loading device, a device for forming an intermediate layer and an unloading device will be described in more detail.

[0202] The apparatus 100 for manufacturing a display device may include a loader 110, a first deposition unit 120, a second deposition unit 130, a third deposition unit 140, and an unloader 150. In one or more embodiments, the apparatus 100 for manufacturing a display device may include a shielding unit 160 disposed between connected devices to disconnect or connect the spaces between the devices. In other words, the shielding unit 160 may serve as a partition between the loader 110, the first deposition unit 120, the second deposition unit 130, the third deposition unit 140, and / or the unloader 150.

[0203] The first intermediate layer, the second intermediate layer, and the third intermediate layer may be deposited on the substrate 21 in various suitable orders by the first deposition part 120, the second deposition part 130, and the third deposition part 140. For example, one of the first intermediate layer, the second intermediate layer, and the third intermediate layer may be deposited on the substrate 21 by the first deposition part 120, another one of the first intermediate layer, the second intermediate layer, and the third intermediate layer may be deposited on the substrate 21 by the second deposition part 130, and yet another one of the first intermediate layer, the second intermediate layer, and the third intermediate layer may be deposited on the substrate 21 by the third deposition part 140. However, hereinafter, for the convenience of description, one or more embodiments in which the first intermediate layer is deposited on the substrate 21 by the first deposition part 120, the second intermediate layer is deposited on the substrate 21 by the second deposition part 130, and the third intermediate layer is deposited on the substrate 21 by the third deposition part 140 will be described in more detail. Hereinafter, for the convenience of description, the first intermediate layer, the second intermediate layer, and the third intermediate layer, respectively, will be described in more detail. Figures 1A to 4B One or more embodiments of the described first sub-pixel, second sub-pixel, and third sub-pixel have the same shape and arrangement.

[0204] The substrate 21 may be inserted from the outside (e.g., the external environment) and temporarily stored in the loader 110. In this case, the loader 110 may store a plurality of substrates 21 or one substrate 21. The loader 110 may receive the substrate 21 from the outside (e.g., the external environment) by using a robotic arm or a movable shuttle disposed therein, and supply the substrate 21 to the first deposition unit 120. In this case, the pixel defining layer may be stacked on the substrate 21. Hereinafter, for ease of description, one or more embodiments in which the loader 110 supports the substrate 21 by using a robotic arm therein, and places the substrate 21 supplied by the robotic arm on the shuttle while supplying it to the first deposition unit 120 will be described in more detail.

[0205] The first intermediate layer can be deposited on the substrate 21 by the first deposition unit 120. In this case, the first deposition unit 120 can be provided as at least one first deposition unit 120. For example, in one or more embodiments, when the first deposition unit 120 is provided, at least one layer of the first intermediate layer can be formed by the first deposition unit 120. In this case, the first deposition unit 120 can include at least one first deposition source 122 to form a layer of the first intermediate layer on the substrate 21. Specifically, when the first deposition source 122 is provided as a plurality of first deposition sources 122 and the first deposition unit 120 forms a plurality of layers of the first intermediate layer, each first deposition source 122 can be replaceable (for example, replaced with another first deposition source in response to exhaustion of the deposition material of each first deposition source 122). In this case, each first deposition source 122 can accommodate different deposition materials. In another embodiment, when the first deposition unit 120 is provided as a plurality of first deposition units 120, each layer of the first intermediate layer can be deposited on the substrate 21 by each first deposition unit 120. In other words, each of the plurality of first deposition units 120 may deposit a corresponding layer of the plurality of layers of the first intermediate layer on the substrate 21. In one or more embodiments, a different deposition material may be deposited on the substrate 21 by each of the first deposition units 120. However, hereinafter, for ease of description, one or more embodiments in which only one first deposition source 122 is provided and the organic emission layer of the first intermediate layer is formed only by the first deposition source 122 will be described in more detail.

[0206] The first deposition part 120 may include a first chamber 121 , a first deposition source 122 , a first mask assembly 123 , a first substrate support 124 , a first mask support 125 , a first magnetic force generator 126 , and a first pressure controller 127 .

[0207] The first chamber 121 may have a space therein and may have one side open so that the substrate 21 can be taken out of or accommodated therein. In this case, a shielding portion 160 including a gate valve may be disposed in the opening portion of the first chamber 121 to selectively open and close the first chamber 121. In one or more embodiments, both sides (e.g., two opposing sides) of the first chamber 121 may be selectively opened and closed to allow the substrate 21 to be taken out of or accommodated by the first chamber 121.

[0208] The first deposition source 122 may contain a first deposition material forming at least one layer of the first intermediate layer. In this case, the first deposition source 122 may evaporate or sublime the first deposition material by applying energy (eg, heat energy, light energy, vibration energy, etc.) to the first deposition material.

[0209] The first deposition source 122 may be replaceable. In this case, when the accommodated first deposition material is exhausted, the first deposition source 122 may be replaced with a new first deposition source 122 .

[0210] The first mask assembly 123 may include a first mask frame 123 - 1 , a first mask sheet 123 - 2 , and a first supporting frame 123 - 3 .

[0211] The first mask frame 123-1 may have an opening at its center. In this case, the first mask frame 123-1 may be formed in a window frame shape. In another embodiment, the first mask frame 123-1 may have an opening at its center, and a separate frame may be arranged to divide the opening in a grid form. Hereinafter, for ease of description, one or more embodiments in which the first mask frame 123-1 has a single opening at its center will be described in more detail.

[0212] The first mask sheet 123-2 may be arranged on one surface of the first mask frame 123-1 while being stretched in at least one of the first and second directions, and may be fixed to the first mask frame 123-1 by welding or the like. In this case, a groove may be formed in the first mask frame 123-1 to accommodate the first mask sheet 123-2. The first mask sheet 123-2 may have a rectangular shape and may be arranged on one side of the first mask frame 123-1. In one or more embodiments, the first mask sheet 123-2 may have a slit shape.

[0213] The first mask sheet 123-2 may be provided as a plurality of first mask sheets 123-2. In this case, the first mask sheets 123-2 may be arranged in a row to be adjacent to each other in the first direction or the second direction. Specifically, in this case, the long sides of the first mask sheets 123-2 may be parallel to the long sides or short sides of the first mask frame 123-1. Hereinafter, for the convenience of description, the arrangement of the long sides of the first mask sheets 123-2 in the first direction will be described in more detail. Figure 6 One or more embodiments in the X-axis direction.

[0214] The first mask sheet 123-2 may include a plurality of first openings 123-4. In this case, the first openings 123-4 may be arranged spaced apart from each other in the first direction and the second direction. Specifically, each first opening 123-4 may have a rhombus shape with its vertices arranged in the stretching direction of the first mask sheet 123-2. Specifically, each first opening 123-4 may have a square shape in which the angle formed between two sides adjacent to each vertex is 90°. In this case, the centers of some of the first openings 123-4 may be arranged in a row in one of the stretching direction of the first mask sheet 123-2 and a direction perpendicular to or perpendicular to the stretching direction of the first mask sheet 123-2. In one or more embodiments, the centers of other openings in the first openings 123-4 may be arranged in a serpentine pattern in one of the stretching direction of the first mask sheet 123-2 and a direction perpendicular to or perpendicular to the stretching direction of the first mask sheet 123-2. In this case, the first opening 123-4 may be arranged to correspond to the reference Figure 4A and Figure 4B When the plurality of first openings 123-4 are formed as described above, even if the first mask sheet 123-2 is stretched, the stretched shape of the first mask sheet 123-2 can be predictable to a certain extent. In other words, in one or more embodiments, the arrangement and shape of the plurality of first openings 123-4 of the first mask sheet 123-2 make the shape of the first mask sheet 123-2 under tension more predictable (i.e., keep the shape within a predictable range).

[0215] The first support frames 123-3 may be arranged on the first mask frame 123-1 to support the first mask frame 123-1 and the first mask sheet 123-2. In this case, the first support frames 123-3 may be arranged in a grid pattern in the first mask frame 123-1 to define a display area of ​​a display device. In other words, the first support frames 123-3 may define multiple display areas by dividing the central opening of the first mask frame 123-1 into multiple areas.

[0216] The first substrate support 124 can support the substrate 21. In this case, the first substrate support 124 can support the substrate 21 when the substrate 21 is placed thereon, or can support the substrate 21 by being bonded or attached to one surface of the substrate 21. For example, the first substrate support 124 may include a frame, a rod, etc. fixed in the first chamber 121. In another embodiment, the first substrate support 124 may include a clamp that clamps the substrate 21. In another embodiment, the first substrate support 124 may include an adhesive chuck or an electrostatic chuck. In this case, the first substrate support 124 may be formed integrally with the first magnetic force generator 126. In another embodiment, the first substrate support 124 may include a shuttle that transfers the substrate 21 from the loader 110. However, hereinafter, for convenience of description, one or more embodiments in which the first substrate support 124 includes a shuttle will be described in more detail.

[0217] The first mask support 125 can support the first mask assembly 123. In this case, because the first mask support 125 can be the same as or similar to the first substrate support 124 described above, a more detailed description thereof is omitted for ease of description. Hereinafter, for ease of description, one or more embodiments will be described in more detail in which the first mask support 125 includes a frame fixed to the first chamber 121, and the first mask assembly 123 is placed on and supported by the frame.

[0218] The first magnetic force generator 126 may be positioned in the first chamber 121 to closely attach the first mask frame 123-1 to the substrate 21. In this case, the first magnetic force generator 126 may include an electromagnet.

[0219] The first pressure controller 127 may be connected to the first chamber 121 to adjust the internal pressure of the first chamber 121. The first pressure controller 127 may include a pipe connected to the first chamber 121 and a pump disposed in the pipe.

[0220] The second deposition part 130 may form a second intermediate layer by depositing a second deposition material on the substrate 21 on which the first intermediate layer is formed. The second deposition part 130 may be similar to the first deposition part 120 described above. In this case, the second deposition part 130 may include a second mask sheet 133-2. The second mask sheet 133-2 may be similar to the first mask sheet 123-2. In this case, the second mask sheet 133-2 may include a plurality of second openings 133-4. The second openings 133-4 may be arranged to be spaced apart from each other. In this case, some of the second openings 133-4 may be spaced apart from each other relative to the stretching direction of the second mask sheet 133-2 (e.g., Figure 7The second openings 133-4 are inclined in one direction (in the X-axis direction of the second mask sheet 133-2 or the length direction of the second mask sheet 133-2). In one or more embodiments, other second openings 133-4 among the second openings 133-4 may be inclined in a direction different from the direction of the second openings 133-4 relative to the stretching direction of the second mask sheet 133-2. For example, the second openings 133-4 may be inclined at an angle other than 0° relative to the stretching direction of the second mask sheet 133-2. Specifically, the second openings 133-4 may be arranged so as to form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet 133-2.

[0221] In one or more embodiments, a straight line can be formed in one direction by connecting or passing through the centers of the second openings 133-4. For example, a straight line can be formed by connecting or passing through the centers of some of the second openings 133-4, and no straight line may be formed by connecting the centers of other second openings 133-4. For example, a straight line can be formed by connecting or passing through the centers of the second openings 133-4 that are arranged in a row in one of the stretching direction of the second mask sheet 133-2 and a direction perpendicular to or perpendicular to the stretching direction of the second mask sheet 133-2. Conversely, the centers of the second openings 133-4 that are arranged in the other of the stretching direction of the second mask sheet 133-2 and a direction perpendicular to or perpendicular to the stretching direction of the second mask sheet 133-2 can be arranged in a serpentine form (or a zigzag form). However, hereinafter, for ease of description, one or more embodiments will be described in more detail in which the centers of some of the second openings 133-4 form a straight line (e.g., by passing through the center), and the centers of other second openings 133-4 do not form a straight line (e.g., forming a serpentine or zigzag shape). In one or more embodiments, the second openings 133-4 may have a rectangular shape.

[0222] As described above, the second mask sheet 133-2 can be secured to the second mask frame using a tensile force applied thereto. In this case, when the second mask sheet 133-2 deforms while all of the second openings 133-4 are tilted in the same direction as the direction of tension of the second mask sheet 133-2, the left and right sides, or the front and rear sides, of the second mask sheet 133-2 may deform to different degrees. Consequently, the deformation of the second mask sheet 133-2 may exceed a predictable range. Specifically, in this case, one side of the second mask sheet 133-2 may deform significantly, while the other side may not deform or may deform only slightly. This may cause the shapes of the second openings 133-4 to distort, or some of the second openings 133-4 may have different shapes from others of the second openings 133-4 under tension. In one or more embodiments, in this case, the centers of some of the second openings 133-4 may not be arranged in a row.

[0223] However, as described above, some of the second openings 133-4 and other second openings 133-4 can be tilted in different directions relative to the stretching direction of the second mask sheet 133-2 and then formed on the second mask sheet 133-2. Therefore, when the second mask sheet 133-2 is stretched, the degree of deformation can be maintained uniformly throughout the second mask sheet 133-2 to a certain extent. Specifically, by tilting adjacent second openings 133-4 in different directions relative to the stretching direction of the second mask sheet 133-2, uniform deformation can be induced throughout the second mask sheet 133-2. In one or more embodiments, each of the plurality of second openings 133-4 can be arranged to form an angle of 45 degrees or approximately 45 degrees relative to the stretching direction of the second mask sheet 133-2 and tilted in a direction different from the direction of another of the plurality of second openings 133-4 relative to the stretching direction of the second mask sheet 133-2.

[0224] The third deposition material may be deposited on the substrate 21 on which the first and second intermediate layers are formed by the third deposition unit 140 to form a third intermediate layer on the substrate 21. In this case, the first intermediate layer, the second intermediate layer, and the third intermediate layer may be arranged so as not to overlap one another in a plane. The third deposition unit 140 may be similar to the first deposition unit 120. Here, the third deposition unit 140 may include a third mask sheet 143-2 having a plurality of third openings 143-4. In this case, the third mask sheet 143-2 may be similar to the second mask sheet 133-2, and the third openings 143-4 may be arranged similarly to the second openings 133-4. However, when the second mask sheet 133-2 and the third mask sheet 143-2 are stacked on each other, the second mask sheet 133-2 and the third mask sheet 143-2 may be manufactured so that the second openings 133-4 and the third openings 143-4 do not overlap one another (e.g., do not overlap when viewed from a plan view).

[0225] The unloader 150 may store (e.g., temporarily store) the substrate 21 on which the first intermediate layer, the second intermediate layer, and the third intermediate layer are formed, and then carry (transfer) the substrate 21 to the outside (e.g., an external environment) or transfer the substrate 21 to another device. In this case, the unloader 150 may include a robot arm that transfers the substrate 21.

[0226] The substrate 21 having the first, second, and third intermediate layers formed thereon as described above may be manufactured as a display panel by forming a counter electrode on the first, second, and third intermediate layers and forming an encapsulation part.

[0227] The operation of the apparatus 100 for manufacturing a display device will be described. As described above, the apparatus 100 for manufacturing a display device can manufacture the first sub-pixel, the second sub-pixel, and the third sub-pixel in various suitable orders. However, hereinafter, for ease of description, the apparatus 100 for manufacturing a display device sequentially manufacturing the first sub-pixel, the second sub-pixel, and the third sub-pixel will be described in more detail. Figure 4A and Figure 4B One or more embodiments of the first sub-pixel, the second sub-pixel, and the third sub-pixel shown in .

[0228] After transferring the substrate 21 to the loader 110 , the loader 110 may transfer the substrate 21 to the first deposition part 120 .

[0229] The first deposition unit 120 supplies the first deposition material to the first deposition source 122 to form a first intermediate layer on the substrate 21. Here, the first deposition material may be deposited on the substrate 21 by passing through the first opening 123-4. In this case, the first intermediate layer may have a square shape that is tilted relative to the stretching direction of the first mask sheet 123-2.

[0230] When the above process is completed, the substrate 21 is transferred from the first deposition part 120 to the second deposition part 130, and then the second deposition material may be deposited on the substrate 21 by the second deposition part 130. In this case, the second deposition part 130 may form a plurality of pairs of second intermediate layers on the substrate 21 that are inclined in different directions relative to the stretching direction of the second mask sheet 133-2 and are adjacent to each other.

[0231] Afterwards, the substrate 21 may be transferred from the second deposition part 130 to the third deposition part 140. The third deposition part 140 may supply a third deposition material onto the substrate 21 and may deposit the third deposition material passing through the third opening 143-4 on the substrate 21. In this case, the third deposition part 140 may form a plurality of pairs of third intermediate layers on the substrate 21 that are inclined in different directions relative to the stretching direction of the third mask sheet 143-2 and are adjacent to each other.

[0232] The substrate 21 on which the first intermediate layer, the second intermediate layer, and the third intermediate layer are formed can be transported to the outside (e.g., the external environment) or supplied to a device (or equipment) for the next operation through the unloader 150. Thereafter, a counter electrode and a thin film encapsulation layer are formed on the substrate 21, completing the manufacture of the display panel.

[0233] Thereafter, an optical functional member is disposed on the display panel, and a barrier is disposed on the optical functional member, so that the manufacture of the display device can be completed.

[0234] Therefore, the apparatus 100 for manufacturing a display device and the method of manufacturing a display device may manufacture a display device having a precise deposition pattern.

[0235] In one or more embodiments, the apparatus 100 for manufacturing a display device and the method of manufacturing a display device may reduce an error between a designed pattern and an actual deposition pattern that may occur during a manufacturing process.

[0236] Figure 11A is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments. Figure 11B It shows Figure 11A FIG. 1 is a plan view of the arrangement of the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 and the barrier layer 52 shown in FIG. Figure 12 is shown for deposition Figure 11A and Figure 11B FIG. 1 is a plan view of a portion of a second mask sheet 133 - 2 of a second intermediate layer 28 - 2B shown in FIG. Figure 13 is shown for deposition Figure 11A and Figure 11BFIG. 1 is a plan view of a portion of a third mask sheet 143 - 2 of a third intermediate layer 28 - 2C shown in FIG.

[0237] Reference Figures 11A to 13 , the display device can be connected with Figure 2A and Figure 2B The same as shown in . In the display panel, a display area and a non-display area outside or around the display area can be defined throughout the substrate. In one or more embodiments, the non-display area surrounds the display area. Subpixels including the first subpixel F1, the second subpixel F2, and the third subpixel F3 can be arranged in the display area, and the power lines can be arranged in the non-display area. In one or more embodiments, the pad portion can be arranged in the non-display area.

[0238] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit light beams of different colors. For example, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit blue light, another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit red light, and yet another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit green light.

[0239] One of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a rectangular shape.

[0240] Hereinafter, for convenience of description, one or more embodiments in which the first subpixel F1 has a square shape and emits red light, the second subpixel F2 has a rectangular shape and emits green light, and the third subpixel F3 has a rectangular shape and emits blue light will be described in more detail.

[0241] The first sub-pixel F1 may include a first intermediate layer 28-2A, and the first intermediate layer 28-2A may correspond to the shape and position of the first sub-pixel F1. In this case, the planar area of ​​the first intermediate layer 28-2A may be greater than or equal to the planar area of ​​the first sub-pixel F1, and the region of the first sub-pixel F1 may be arranged in the region of the first intermediate layer 28-2A.

[0242] The second sub-pixel F2 may include a second intermediate layer 28-2B. In one or more embodiments, the second intermediate layer 28-2B may correspond to the shape and position of the second sub-pixel F2. In this case, the area of ​​the second sub-pixel F2 may be arranged in the area of ​​the second intermediate layer 28-2B.

[0243] The third sub-pixel F3 may include a third intermediate layer 28-2C. In one or more embodiments, the third intermediate layer 28-2C may correspond to the shape and position of the third sub-pixel F3. In this case, the area of ​​the third sub-pixel F3 may be arranged in the area of ​​the third intermediate layer 28-2C.

[0244] Each of the second sub-pixel F2 and the third sub-pixel F3 may have various suitable planar areas.

[0245] In one or more embodiments, the planar areas of some of the multiple second subpixels F2 may be different from the planar areas of other second subpixels F2 among the multiple second subpixels F2, and the planar areas of some of the multiple third subpixels F3 may be different from the planar areas of other third subpixels F3 among the multiple third subpixels F3.

[0246] In another embodiment, the second subpixel F2 may have the same planar area, and the third subpixel F3 may have the same planar area. In this case, the planar area of ​​the second subpixel F2 may be different from the planar area of ​​the third subpixel F3. For example, one of the planar area of ​​the second subpixel F2 and the planar area of ​​the third subpixel F3 may be smaller than the other of the planar area of ​​the second subpixel F2 and the planar area of ​​the third subpixel F3. In one or more embodiments, the planar area of ​​the second subpixel F2 may be smaller than the planar area of ​​the third subpixel F3. In another embodiment, the planar area of ​​the third subpixel F3 may be smaller than the planar area of ​​the second subpixel F2. Therefore, the aperture ratio of light emitted from each subpixel may be adjustable.

[0247] In the above case, the long side of the second subpixel F2 and the long side of the third subpixel F3 may have the same size. However, the short side of the second subpixel F2 and the short side of the third subpixel F3 may be different from each other.

[0248] As described above, the area of ​​at least one of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 can be adjusted by adjusting the area of ​​the exposed pixel electrode of the pixel defining layer. In this case, the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C formed by being deposited in the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, respectively, can have an area and shape corresponding to the area and shape of each sub-pixel to prevent or substantially prevent the sub-pixels from overlapping each other.

[0249] The second mask sheet 133-2 and the third mask sheet 143-2 can be used to form the second intermediate layer 28-2B and the third intermediate layer 28-2C. In this case, the second mask sheet 133-2 may include a plurality of second openings 133-4, and the third mask sheet 143-2 may include a plurality of third openings 143-4. In this case, the area of ​​each second opening 133-4 may be different from the area of ​​each third opening 143-4. Specifically, the area of ​​each second opening 133-4 and the area of ​​each third opening 143-4 may correspond to the area of ​​the second intermediate layer 28-2B and the area of ​​the third intermediate layer 28-2C, respectively. The relationship between each sub-pixel, each intermediate layer, and each opening as described above can be applied to all embodiments of the present disclosure.

[0250] Two adjacent second openings 133-4 among the second openings 133-4 may be tilted in opposite directions relative to the stretching direction of the second mask sheet 133-2. In one or more embodiments, two adjacent third openings 143-4 among the third openings 143-4 may be tilted in opposite directions relative to the stretching direction of the third mask sheet 143-2.

[0251] In the above case, even when the second mask sheet 133-2 and the third mask sheet 143-2 are stretched, the shapes of the second opening 133-4 and the third opening 143-4 can be maintained to be almost similar to their initial states. In one or more embodiments, when the positions of the second opening 133-4 and the third opening 143-4 are changed from their initial positions, the positions move within a certain predictable range, so that when the second deposition material and the third deposition material are later deposited on the display substrate, the pattern can be corrected to a certain extent.

[0252] In the above case, the spacer P may be arranged between some of the sub-pixels. In this case, the spacer P is aligned with the reference Figure 4A and Figure 4B In one or more embodiments, the arrangement of each sub-pixel, the distance from the edge of a sub-pixel to the edge of another sub-pixel, and the distance from the edge of the spacer P to the edge of each sub-pixel are the same as or similar to those described in the reference image. Figure 4A and Figure 4B Those described are the same, so a more detailed description thereof will be omitted.

[0253] The display device may be fixed to a device that transports a user, such as a vehicle. In this case, the display device may be fixed to the device so that a predetermined or set angle other than 0° is formed between the user's gaze direction and the first direction or the second direction. For example, the display device may be arranged so that a 90° angle is formed between the user's gaze direction when viewing the display device and the first direction or the second direction.

[0254] In the above case, when a user views the display device, the inclined portion of the pixel defining layer and the gaze direction are not perpendicular to each other, and therefore, external light may be reflected by the inclined portion of the pixel defining layer, and the external light may be prevented or substantially prevented from entering the user's eyes. In other words, the inclined portion may prevent or substantially prevent external light from being reflected into the user's eyes.

[0255] In one or more embodiments, the display device can achieve accurate images through each sub-pixel.

[0256] The display device may include a barrier portion having a barrier layer 52. In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52 and may be arranged to be spaced apart from each other. Figure 4A and Figure 4B As described, each barrier layer 52 may be disposed on the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 .

[0257] Thus, the display device can prevent or substantially prevent moire from occurring in the display device due to external light or operation of the display device. In one or more embodiments, the display device can be provided with a barrier layer 52 to prevent or substantially prevent images, characters, etc. from being formed or reflected in the window of the vehicle.

[0258] The display device may be manufactured by an apparatus for manufacturing a display device. In this case, the apparatus for manufacturing a display device may be Figure 5 and Figure 6 The apparatus for manufacturing a display device shown in FIG is similarly formed. In this case, the first deposition portion can be formed by using Figure 7 The first mask assembly 123 shown in FIG. 1 is used to form the first intermediate layer 28-2A, and the second deposition part and the third deposition part (not shown) can be formed by using Figure 12 and Figure 13 The second mask sheet 133 - 2 and the third mask sheet 143 - 2 shown in FIG. 1 form the second intermediate layer 28 - 2B and the third intermediate layer 28 - 2C on the display substrate by using a deposition material passing through the second opening 133 - 4 and the third opening 143 - 4 , respectively.

[0259] An apparatus for manufacturing a display device and a method of manufacturing the display device can manufacture a display device having a precise deposition pattern by minimizing deformation of each mask sheet.

[0260] In one or more embodiments, an apparatus for manufacturing a display device and a method of manufacturing a display device may reduce an error between a designed pattern and an actual deposition pattern that may occur during a manufacturing process.

[0261] Figure 14A is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments. Figure 14B It shows Figure 14A FIG. 1 is a plan view of the arrangement of the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 and the barrier layer 52 shown in FIG. Figure 15 is shown for deposition Figure 14A and Figure 14B FIG. 1 is a plan view of a portion of a first mask sheet 123 - 2 of a first intermediate layer 28 - 2A shown in FIG. Figure 16 is shown for deposition Figure 14A and Figure 14B FIG. 1 is a plan view of a portion of a second mask sheet 133 - 2 of a second intermediate layer 28 - 2B shown in FIG. Figure 17 is shown for deposition Figure 14A and Figure 14B FIG. 1 is a plan view of a portion of a third mask sheet 143 - 2 of a third intermediate layer 28 - 2C shown in FIG.

[0262] Reference Figures 14A to 17 , the display device can be connected with Figure 2A and Figure 2B The display device shown in is the same as that shown in . In the display panel, a display area and a non-display area outside or around the display area can be defined throughout the substrate. In one or more embodiments, the non-display area surrounds the display area. Subpixels including a first subpixel F1, a second subpixel F2, and a third subpixel F3 can be arranged in the display area, and the power lines can be arranged in the non-display area. In one or more embodiments, the pad portion can be arranged in the non-display area. The display device is the same as or similar to the above-mentioned display device, and therefore, a more detailed description thereof will be omitted.

[0263] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit light beams of different colors. For example, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit blue light, another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit red light, and yet another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit green light.

[0264] One of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a rectangular shape.

[0265] Hereinafter, for the convenience of description, one or more embodiments in which the first sub-pixel F1 has a square shape and emits red light, the second sub-pixel F2 has a rectangular shape and emits green light, and the third sub-pixel F3 has a rectangular shape and emits blue light will be described in more detail. In this case, the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may be the same as those in the reference Figures 1A to 4B Similar to those described above. However, the edge of each sub-pixel can be chamfered. That is, the edge portion of each sub-pixel can be rounded or inclined.

[0266] The first sub-pixel F1 may include a first intermediate layer 28-2A, and the first intermediate layer 28-2A may correspond to the shape and position of the first sub-pixel F1. In this case, the planar area of ​​the first intermediate layer 28-2A may be greater than or equal to the planar area of ​​the first sub-pixel F1, and the region of the first sub-pixel F1 may be arranged in the region of the first intermediate layer 28-2A.

[0267] The second sub-pixel F2 may include a second intermediate layer 28-2B. In one or more embodiments, the second intermediate layer 28-2B may correspond to the shape and position of the second sub-pixel F2. The region of the second sub-pixel F2 may be arranged in the region of the second intermediate layer 28-2B.

[0268] The third sub-pixel F3 may include a third intermediate layer 28-2C. In one or more embodiments, the third intermediate layer 28-2C may correspond to the shape and position of the third sub-pixel F3. In this case, the area of ​​the third sub-pixel F3 may be arranged in the area of ​​the third intermediate layer 28-2C.

[0269] The spacer P may be arranged between the sub-pixels. Figures 1A to 4B The described spacers P are the same or similar, and therefore, a more detailed description thereof will be omitted.

[0270] In order to manufacture the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, a substrate may be supplied to a reference Figure 5 and Figure 6 An apparatus for manufacturing a display device is described.

[0271] In this case, the first deposition part may supply the first deposition material to the substrate to form the first intermediate layer 28-2A, the second deposition part may supply the second deposition material to the substrate to form the second intermediate layer 28-2B, and the third deposition part may supply the third deposition material to the substrate to form the third intermediate layer 28-2C.

[0272] The first mask sheet 123-2 used by the first deposition unit may include a first opening 123-4 formed in a shape corresponding to the first sub-pixel F1. The planar area of ​​the first opening 123-4 may be greater than or equal to the planar area of ​​the first sub-pixel F1 corresponding to the first opening 123-4. In one or more embodiments, the planar area of ​​the first opening 123-4 may be less than or equal to the planar area of ​​the first intermediate layer 28-2A formed by depositing the first deposition material passing through the first opening 123-4 on the substrate. Here, the first opening 123-4, the first intermediate layer 28-2A, and the first sub-pixel F1 corresponding to each other may all have the same square shape.

[0273] The second opening 133-4 of the second mask sheet 133-2 used by the second deposition unit may also be formed to correspond to the shape of the second sub-pixel F2. Here, the second opening 133-4 may be arranged in the same manner as the second sub-pixel F2. In this case, the planar area of ​​the second opening 133-4 may be greater than or equal to the planar area of ​​the second sub-pixel F2, and may be less than or equal to the planar area of ​​the second intermediate layer 28-2B formed by depositing the second deposition material on the substrate.

[0274] The third opening 143-4 of the third mask sheet 143-2 used by the third deposition unit may also be formed to correspond to the shape of the third sub-pixel F3, and the planar area of ​​the third opening 143-4 may be greater than or equal to the planar area of ​​the third sub-pixel F3. In one or more embodiments, the planar area of ​​the third opening 143-4 may be less than or equal to the planar area of ​​the third intermediate layer 28-2C.

[0275] In this case, the relationship between the first sub-pixel F1, the second sub-pixel F2 and the third sub-pixel F3 can be the same as that of the reference Figure 4A and Figure 4B In one or more embodiments, the relationship among the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may be the same as the relationship among the first subpixel F1, the second subpixel F2, and the third subpixel F3.

[0276] For example, the centers of some of the second subpixels F2 may be arranged in a straight line in one direction, and the centers of other of the second subpixels F2 may be arranged in a serpentine form in another direction. In one or more embodiments, the centers of some of the third subpixels F3 may be arranged in a straight line in one direction, and the centers of other of the third subpixels F3 may be arranged in a serpentine form in another direction. The centers of the first subpixels F1 may be arranged in a straight line in a direction different from the one direction.

[0277] In one or more embodiments, one side of each of the second subpixel F2 and the third subpixel F3 may be tilted in opposite directions relative to the stretching direction of the second mask sheet 133-2 and the stretching direction of the third mask sheet 143-2, and the second subpixel F2 and the third subpixel F3 may face the same first subpixel F1. Specifically, in this case, the adjacent second subpixels F2 may form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet 133-2 in the opposite direction. In this case, one side of each of the second openings 133-4 may also form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet 133-2. The second openings 133-4 are formed in the second mask sheet 133-2 and are adjacent to each other. In one or more embodiments, an angle of 45° or approximately 45° may be formed between one side of each of the adjacent third subpixels F3 and the stretching direction of the third mask sheet 143-2 in the opposite direction. Furthermore, one side of each of the third openings 143-4 may also form an angle of 45° or approximately 45° relative to the stretching direction of the third mask sheet 143-2, and the third openings 143-4 may be formed in the third mask sheet 143-2 and adjacent to each other. In this case, the second intermediate layer 28-2B and the third intermediate layer 28-2C may be arranged on the substrate at positions corresponding to the second opening 133-4 and the third opening 143-4, respectively. The direction of one side of the first opening 123-4 to one side of the third opening 143-4 is not limited thereto and may vary depending on the positions of the first to third subpixels F1 to F3. That is, each of one side of the first opening 123-4 to one side of the third opening 143-4 may be inclined at an angle of 85° or less relative to the stretching direction of the first to third mask sheets 123-2.

[0278] The display device may include a barrier portion having a barrier layer 52. In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52 and may be arranged to be spaced apart from each other. Figure 4A and Figure 4BAs described, each barrier layer 52 may be disposed on the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 .

[0279] Thus, the display device can prevent or substantially prevent moire phenomena that occur due to external light or operation of the display device. In one or more embodiments, during operation, the display device can prevent or substantially prevent images, characters, etc. displayed on the display device from being formed or reflected in the window of the vehicle.

[0280] The display device may be fixed to a device that transports a user, such as a vehicle. In this case, the display device may be fixed to the device so that a predetermined or set angle other than 0° is formed between the user's gaze direction and the first direction or the second direction. For example, the display device may be arranged so that a 90° angle is formed between the user's gaze direction when viewing the display device and the first direction or the second direction.

[0281] In the above case, when a user views the display device, the inclined portion of the pixel defining layer and the gaze direction are not perpendicular to each other, and therefore, external light may be reflected by the inclined portion of the pixel defining layer, and the external light may be prevented or substantially prevented from entering the user's eyes. In other words, the inclined portion may prevent or substantially prevent external light from being reflected into the user's eyes.

[0282] In one or more embodiments, the display device can achieve accurate images through each sub-pixel.

[0283] The display device can prevent or substantially prevent a moire pattern from being formed on a surface thereof, which may occur during operation of the display device or due to external light.

[0284] An apparatus for manufacturing a display device and a method of manufacturing a display device can manufacture a display device having a precise deposition pattern.

[0285] In one or more embodiments, an apparatus for manufacturing a display device and a method of manufacturing a display device may reduce an error between a designed pattern and an actual deposition pattern that may occur during a manufacturing process.

[0286] Figure 18A is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments. Figure 18B It shows Figure 18A FIG. 1 is a plan view of the arrangement of the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 and the barrier layer 52 shown in FIG. Figure 19 is shown for deposition Figure 18A and Figure 18BFIG. 1 is a plan view of a portion of a second mask sheet 133 - 2 of a second intermediate layer 28 - 2B shown in FIG. Figure 20 is shown for deposition Figure 18A and Figure 18B FIG. 1 is a plan view of a portion of a third mask sheet 143 - 2 of a third intermediate layer 28 - 2C shown in FIG.

[0287] Reference 18A to 20 , the display device can be connected with Figure 2A and Figure 2B The display device shown in FIG. In the display panel, a display area and a non-display area outside or around the display area can be defined across the substrate. In one or more embodiments, the non-display area surrounds the display area. Subpixels including a first subpixel F1, a second subpixel F2, and a third subpixel F3 can be arranged in the display area, and the lines of force can be arranged in the non-display area. In one or more embodiments, the pad portion can be arranged in the non-display area.

[0288] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit light beams of different colors. For example, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit blue light, another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit red light, and yet another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit green light.

[0289] One of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a rectangular shape.

[0290] Hereinafter, for convenience of description, one or more embodiments in which the first subpixel F1 has a square shape and emits red light, the second subpixel F2 has a rectangular shape and emits green light, and the third subpixel F3 has a rectangular shape and emits blue light will be described in more detail.

[0291] The first sub-pixel F1 may include a first intermediate layer 28-2A, and the first intermediate layer 28-2A may correspond to the shape and position of the first sub-pixel F1. In this case, the planar area of ​​the first intermediate layer 28-2A may be greater than or equal to the planar area of ​​the first sub-pixel F1, and the region of the first sub-pixel F1 may be arranged in the region of the first intermediate layer 28-2A.

[0292] The second sub-pixel F2 may include a second intermediate layer 28-2B. In one or more embodiments, the second intermediate layer 28-2B may correspond to the shape and position of the second sub-pixel F2. In this case, the area of ​​the second sub-pixel F2 may be arranged in the area of ​​the second intermediate layer 28-2B.

[0293] The third sub-pixel F3 may include a third intermediate layer 28-2C. In one or more embodiments, the third intermediate layer 28-2C may correspond to the shape and position of the third sub-pixel F3. In this case, the area of ​​the third sub-pixel F3 may be arranged in the area of ​​the third intermediate layer 28-2C.

[0294] The first sub-pixel F1, the second sub-pixel F2 and the third sub-pixel F3 may be used in the same or similar manner. Figure 11A and Figure 11B The structure shown in FIG, and the first sub-pixel F1, the second sub-pixel F2 and the third sub-pixel F3 can be Figure 11A and Figure 11B Arranged in the same or similar manner as described.

[0295] Here, at least one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may have a chamfered edge. For example, in one or more embodiments, the vertices of one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may be chamfered, and the vertices of the other two of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may not be chamfered. In another embodiment, the vertices of two of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may be chamfered, and the vertices of another one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may not be chamfered. In another embodiment, the vertices of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may all be chamfered. Below, for ease of description, one or more embodiments in which the vertices of the first subpixel F1, the second subpixel F2, and the third subpixel F3 are all chamfered will be described in more detail.

[0296] In order to form the chamfered vertices of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, the vertices (or corners) of the first opening of the first mask sheet, the vertices (or corners) of the second opening 133-4 of the second mask sheet 133-2, and the vertices (or corners) of the third opening 143-4 of the third mask sheet 143-2 may be chamfered. In this case, the shape of each of the first opening, the second opening 133-4, and the third opening 143-4 may have a shape that is the same as or similar to an octagonal shape. Specifically, the chamfered portions of the first opening, the second opening 133-4, and the third opening 143-4 may be rounded, and the first opening may be as shown in FIG. Figure 15, and the second opening 133 - 4 and the third opening 143 - 4 may be formed as shown in FIG. Figure 19 and Figure 20 , it is shown to be formed to have an inclined shape.

[0297] As described above, in one or more embodiments in which the vertices of the first opening, the second opening 133-4, and the third opening 143-4 are chamfered, when each of the first mask sheet, the second mask sheet 133-2, and the third mask sheet 143-2 is stretched, stress is not concentrated on the vertices of the first opening, the second opening 133-4, and the third opening 143-4.

[0298] Therefore, when each of the first mask sheet, the second mask sheet 133-2, and the third mask sheet 143-2 is stretched, damage to the first mask sheet, the second mask sheet 133-2, and the third mask sheet 143-2 can be prevented or substantially prevented. In one or more embodiments, the first deposition material, the second deposition material, and the third deposition material are deposited on the vertices of the first opening, the second opening 133-4, and the third opening 143-4, respectively, so that the deposition materials do not block each other. As a result, the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C can be formed with precise shapes.

[0299] Can be achieved through Figure 5 and Figure 6 The display device is manufactured using an apparatus that is the same as or similar to an apparatus for manufacturing a display device.

[0300] In this case, the first deposition part may supply the first deposition material to the substrate to form the first intermediate layer 28-2A, the second deposition part may supply the second deposition material to the substrate to form the second intermediate layer 28-2B, and the third deposition part may supply the third deposition material to the substrate to form the third intermediate layer 28-2C.

[0301] The first mask sheet used by the first deposition unit may include a first opening formed in a shape corresponding to the first sub-pixel F1. The planar area of ​​the first opening may be greater than or equal to the planar area of ​​the first sub-pixel F1 corresponding to the first opening. In one or more embodiments, the planar area of ​​the first opening may be less than or equal to the planar area of ​​the first intermediate layer 28-2A formed by depositing the first deposition material passing through the first opening on the substrate. Here, the first opening, the first intermediate layer 28-2A, and the first sub-pixel F1, which correspond to each other, may all have corresponding shapes.

[0302] The second opening 133-4 of the second mask sheet 133-2 used by the second deposition unit may also be formed to correspond to the shape of the second sub-pixel F2. Here, the second opening 133-4 may be arranged in the same manner as the second sub-pixel F2. In this case, the planar area of ​​the second opening 133-4 may be greater than or equal to the planar area of ​​the second sub-pixel F2, and may be less than or equal to the planar area of ​​the second intermediate layer 28-2B formed by depositing the second deposition material on the substrate.

[0303] The third opening 143-4 of the third mask sheet 143-2 used by the third deposition unit may also be formed to correspond to the shape of the third sub-pixel F3, and the planar area of ​​the third opening 143-4 may be greater than or equal to the planar area of ​​the third sub-pixel F3. In one or more embodiments, the planar area of ​​the third opening 143-4 may be less than or equal to the planar area of ​​the third intermediate layer 28-2C.

[0304] In this case, the first sub-pixel F1, the second sub-pixel F2 and the third sub-pixel F3 may be aligned with the reference Figure 11A and Figure 11B In one or more embodiments, the relationship among the first intermediate layer 28 - 2A, the second intermediate layer 28 - 2B, and the third intermediate layer 28 - 2C may be the same as the relationship among the first subpixel F1, the second subpixel F2, and the third subpixel F3.

[0305] For example, the centers of some of the second subpixels F2 may be arranged in a straight line in one direction, and the centers of other of the second subpixels F2 may be arranged in a serpentine form in another direction. In one or more embodiments, the centers of some of the third subpixels F3 may be arranged in a straight line in one direction, and the centers of other of the third subpixels F3 may be arranged in a serpentine form in another direction. The centers of the first subpixels F1 may be arranged in a straight line in a direction different from the one direction.

[0306] In one or more embodiments, the second subpixel F2 and the third subpixel F3 facing the same first subpixel F1 may be tilted in opposite directions relative to the stretching direction of the second mask sheet 133-2 and the stretching direction of the third mask sheet 143-2. ​​Specifically, in this case, the adjacent second subpixels F2 may form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet 133-2. In addition, the second openings 133-4 formed in the second mask sheet 133-2 and adjacent to each other may also form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet 133-2. Each of the adjacent third subpixels F3 may form an angle of 45° or approximately 45° in the opposite direction relative to the stretching direction of the third mask sheet 143-2. In one or more embodiments, the third openings 143-4 may also form an angle of 45° or approximately 45° relative to the stretching direction of the third mask sheet 143-2, and the third openings 143-4 may be formed in the third mask sheet 143-2 and adjacent to each other. In this case, the second intermediate layer 28-2B and the third intermediate layer 28-2C may be arranged on the substrate at positions corresponding to the second opening 133-4 and the third opening 143-4, respectively.

[0307] The display device may be fixed to a device that transports a user, such as a vehicle. In this case, the display device may be fixed to the device so that a predetermined or set angle other than 0° is formed between the user's gaze direction and the first direction or the second direction. For example, the display device may be arranged so that a 90° angle is formed between the user's gaze direction when viewing the display device and the first direction or the second direction.

[0308] In the above case, when a user views the display device, the inclined portion of the pixel defining layer and the gaze direction are not perpendicular to each other, and therefore, external light may be reflected by the inclined portion of the pixel defining layer, and the external light may be prevented or substantially prevented from entering the user's eyes. In other words, the inclined portion may prevent or substantially prevent external light from being reflected into the user's eyes.

[0309] In one or more embodiments, the display device can achieve accurate images through each sub-pixel.

[0310] The display device may include a barrier portion having a barrier layer 52. In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52 and may be arranged to be spaced apart from each other. Figure 4A and Figure 4B As described, each barrier layer 52 may be disposed on the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 .

[0311] Therefore, the display device can prevent or substantially prevent the moire phenomenon from being seen from outside the display device (eg, from an external environment) due to external light or operation of the display device.

[0312] An apparatus for manufacturing a display device and a method of manufacturing a display device can manufacture a display device having a precise deposition pattern.

[0313] In one or more embodiments, an apparatus for manufacturing a display device and a method of manufacturing a display device may reduce an error between a designed pattern and an actual deposition pattern that may occur during a manufacturing process.

[0314] Figure 21 is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments.

[0315] Reference Figure 21 , the display device can be connected with Figure 2A and Figure 2B In this case, the display panel may be formed identically or similarly to the above-described display panel. Here, the display device may include a display panel having a first sub-pixel F1, a second sub-pixel F2, and a third sub-pixel F3.

[0316] The subpixels may include a first subpixel F1, a second subpixel F2, and a third subpixel F3. In this case, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may have a rectangular shape. Hereinafter, for ease of description, one or more embodiments in which the first subpixel F1 has a square shape and the second subpixel F2 and the third subpixel F3 have a rectangular shape will be described in more detail.

[0317] One of the first, second, and third subpixels F1, F2, and F3 emits blue light, another of the first, second, and third subpixels F1, F2, and F3 emits red light, and yet another of the first, second, and third subpixels F1, F2, and F3 emits green light. In this case, depending on the shape of each of the first, second, and third subpixels F1, F2, and F3, one of the blue, red, and green lights may have a square shape, and the other of the blue, red, and green lights may have a rectangular shape. Below, for ease of description, one or more embodiments in which the first subpixel F1 emits blue light, the second subpixel F2 emits red light, and the third subpixel F3 emits green light will be described in more detail.

[0318] The areas of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may be configured differently. In this case, since the aperture ratio of each subpixel is adjustable, a display device having various suitable shapes and capable of performing various suitable operations can be realized.

[0319] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may include a first intermediate layer 28-2A, a second intermediate layer 28-2B, and a third intermediate layer 28-2C, respectively. In this case, the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may include materials (e.g., organic light-emitting layers) that emit different light beams when external power is applied thereto.

[0320] The first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may correspond to the shapes of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, respectively. For example, the first intermediate layer 28-2A may have a square shape to correspond to the square shape of the first sub-pixel F1. In one or more embodiments, the second intermediate layer 28-2B and the third intermediate layer 28-2C may have a rectangular shape to correspond to the rectangular shapes of the second sub-pixel F2 and the third sub-pixel F3, respectively. In this case, the planar area of ​​each intermediate layer may be the same as or different from the planar area of ​​each sub-pixel. For example, in one or more embodiments, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2, the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1, and the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, and the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1. In another embodiment, the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, and the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3. In another embodiment, the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, and the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2. In another embodiment, the planar area of ​​the first intermediate layer 28-2A may be different from the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be different from the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be different from the planar area of ​​the third sub-pixel F3.In another embodiment, the planar area of ​​the first intermediate layer 28-2A may be the same as the planar area of ​​the first sub-pixel F1, the planar area of ​​the second intermediate layer 28-2B may be the same as the planar area of ​​the second sub-pixel F2, and the planar area of ​​the third intermediate layer 28-2C may be the same as the planar area of ​​the third sub-pixel F3. In this case, the planar area may be the area of ​​the plane formed by the display area of ​​the display device. Alternatively, the planar area may be the area of ​​the plane on which the image is realized when the image is realized. Hereinafter, for ease of description, one or more embodiments in which the planar area of ​​each intermediate layer is different from the planar area of ​​each sub-pixel will be described in more detail.

[0321] The first sub-pixels F1, the second sub-pixels F2, and the third sub-pixels F3 may be provided as a plurality of first sub-pixels F1, a plurality of second sub-pixels F2, and a plurality of third sub-pixels F3, respectively. The first sub-pixels F1 may be spaced apart from each other in at least one of the first direction and the second direction. For example, some of the first sub-pixels F1 may be arranged in a first direction (e.g., Figure 21 , and the other first sub-pixels F1 in the first sub-pixels F1 may be arranged in a second direction (eg, Figure 21 The centers of the first subpixels F1 arranged in the first direction among the first subpixels F1 may be arranged in a straight line, and the straight line may be arranged in the same direction as the first direction. In one or more embodiments, the centers of the first subpixels F1 arranged in the second direction among the first subpixels F1 may be arranged in a straight line, and the straight line may be arranged in the same direction as the second direction.

[0322] A predetermined or set angle may be formed between the first side S1 and the second side S2 of each first subpixel F1. Specifically, the first side S1 and the second side S2 of the first subpixel F1 may be perpendicular to each other. In this case, the first side S1 and the second side S2 may be inclined in different directions relative to at least one of the first direction and the second direction. Therefore, each first subpixel F1 may be arranged in a diamond shape based on one of the first direction and the second direction, and the angle formed between the two sides (e.g., the first side S1 and the second side S2) adjacent to each vertex of each first subpixel F1 may be 90°.

[0323] In this case, one second subpixel F2 or one third subpixel F3 may be arranged to face the first subpixel F1 at the first side S1 or the second side S2 of one first subpixel F1. The second subpixel F2 and the third subpixel F3 may be tilted relative to one of the first direction and the second direction. Specifically, the second subpixel F2 and the third subpixel F3 may be tilted so as to form an angle of 45° or approximately 45° relative to one of the first direction and the second direction. For example, an angle of 45° or approximately 45° may be formed between at least one of the short side and the long side of at least one of the second subpixel F2 and the third subpixel F3 and a straight line connecting or passing through the center of the first subpixel F1 arranged in the first direction.

[0324] The second subpixel F2 and the third subpixel F3 may each have a rectangular shape. Here, the area of ​​at least one of the second subpixel F2 and the third subpixel F3 may be smaller than the area of ​​the first subpixel F1. In one or more embodiments, at least one of the second subpixel F2 and the third subpixel F3 facing the first subpixel F1 may be arranged to overlap with a side (e.g., the first side S1 or the second side S2) of the first subpixel F1 facing the second subpixel F2 and the third subpixel F3 (in a direction parallel to the plane defined by the X-axis and the Y-axis), and / or may be arranged to overlap with an extension line of the side of the first subpixel F1 (in a direction parallel to the plane defined by the X-axis and the Y-axis). For example, at least a side of the second subpixel F2 and at least a side of the third subpixel F3 adjacent to the second subpixel F2 may be arranged within the length range of one of the first side S1 and the second side S2. A short side or a long side of at least one of the second subpixel F2 and the third subpixel F3 facing one first subpixel F1 may be parallel to the first side S1 or the second side S2 .

[0325] For example, in one or more embodiments, the extension lines of the short sides of different second subpixels F2 facing the first side S1 and the second side S2, respectively, may intersect with each other, or the extension lines of the long sides of different second subpixels F2 facing the first side S1 and the second side S2, respectively, may intersect with each other. In another embodiment, the extension lines of the short sides of the third subpixel F3 facing the first side S1 and the second side S2, respectively, may intersect with each other, or the extension lines of the long sides of the third subpixel F3 facing the first side S1 and the second side S2, respectively, may intersect with each other. In another embodiment, the extension line of the short side of the second subpixel F2 facing the first side S1 may intersect with the extension line of the short side of the third subpixel F3 facing the second side S2, or the extension line of the long side of the second subpixel F2 facing the first side S1 may intersect with the extension line of the long side of the third subpixel F3 facing the second side S2. In another embodiment, the extension line of the long side of the second sub-pixel F2 facing the first side S1 may intersect with the extension line of the short side of the third sub-pixel F3 facing the second side S2, or the extension line of the short side of the second sub-pixel F2 facing the first side S1 may intersect with the extension line of the long side of the third sub-pixel F3 facing the second side S2.

[0326] The second sub-pixels F2 may be arranged to be spaced apart from each other in at least one of the first and second directions. In one or more embodiments, the centers of some of the second sub-pixels F2 arranged in the first or second direction in the second sub-pixels F2 may be positioned in a straight line. In another embodiment, the centers of some of the second sub-pixels F2 arranged in one of the first and second directions in the second sub-pixels F2 may be arranged in a straight line, and the centers of other second sub-pixels F2 arranged in the other of the first and second directions in the second sub-pixels F2 may be arranged in a serpentine (or zigzag) form in the other of the first and second directions. Hereinafter, for ease of description, one or more embodiments in which the centers of some of the second sub-pixels F2 arranged in the first direction in the second sub-pixels F2 are arranged in a straight line, and the centers of other second sub-pixels F2 arranged in the second direction in the second sub-pixels F2 are arranged in a serpentine form will be described in more detail.

[0327] Similar to the second sub-pixels F2, the third sub-pixels F3 may be arranged to be spaced apart from each other in at least one of the first and second directions. In this case, the third sub-pixels F3 may be arranged in a manner similar to the second sub-pixels F2. Hereinafter, for ease of description, one or more embodiments will be described in more detail in which the centers of some of the third sub-pixels F3 arranged in the first direction are arranged in a straight line, while the centers of other third sub-pixels F3 arranged in the second direction are arranged in a serpentine form.

[0328] In the above case, one of the second subpixel F2 and the third subpixel F3 facing the first side S1 of the first subpixel F1 can be arranged symmetrically with one of the second subpixel F2 and the third subpixel F3 facing the second side S2 of the first subpixel F1 relative to or about a straight line connecting or passing through the center of the first subpixel F1 arranged in the first direction (or a straight line passing through the centers of two adjacent subpixels and parallel to the first direction). For example, the second subpixel F2 facing the first side S1 can be symmetrical with the third subpixel F3 facing the second side S2 relative to or about the straight line. In one or more embodiments, the third subpixel F3 facing the first side S1 can be symmetrical with the second subpixel F2 facing the second side S2 relative to or about the straight line. In this case, the distance between the centers of the adjacent second subpixels F2 can be the same as the distance between the centers of the adjacent third subpixels F3. In another embodiment, the second subpixel F2 and the third subpixel F3 facing the first side S1 can be symmetrical with the second subpixel F2 and the third subpixel F3 facing the second side S2 relative to or about the straight line. In this case, the distance between the centers of one of the pair of second subpixels F2 and the pair of third subpixels F3 arranged symmetrically with each other can be smaller than the distance between the centers of the other pair of second subpixels F2 and the pair of third subpixels F3 arranged symmetrically with each other. In this case, the adjacent pair of second subpixels F2 can be positioned between the adjacent pair of third subpixels F3, or the adjacent pair of third subpixels F3 can be positioned between the adjacent pair of second subpixels F2. However, hereinafter, for ease of description, one or more embodiments in which the second subpixels F2 are arranged symmetrically with respect to or about a straight line connecting or passing through the centers of the first subpixels F1 arranged in the first direction will be described in more detail.

[0329] When arranged as described above, the first distance L1, which is the shortest distance from the edge of the first subpixel F1 to the second subpixel F2, may be the same as the second distance L2, which is the shortest distance from the edge of the first subpixel F1 to the third subpixel F3. In this case, the shortest distance may be measured from the first side S1 or the second side S2 to an edge of the second subpixel F2 or an edge of the third subpixel F3 in a direction perpendicular to or perpendicular to one of the first and second sides S1 and S2. Alternatively, in another embodiment, the shortest distance may be measured from the first side S1 (or the extension of the first side S1) or the second side S2 (or the extension of the second side S2) to an edge of the second subpixel F2 or an edge of the third subpixel F3 in a direction perpendicular to or perpendicular to an extension of one of the first and second sides S1 and S2. However, hereinafter, for ease of description, one or more embodiments in which the shortest distance is the distance measured between the first side S1 or an extension of the first side S1 and the second subpixel F2 and the third subpixel F3 facing the first side S1 will be described in more detail. In another embodiment, the shortest distance may be measured as the distance from the center of the first subpixel F1 to the center of the second subpixel F2 or the distance from the center of the first subpixel F1 to the center of the third subpixel F3. In another embodiment, the shortest distance may be measured as the distance from the first side S1 of the first subpixel F1 or an extension of the first side S1 to the center of the second subpixel F2 or the distance from the first side S1 of the first subpixel F1 or an extension of the first side S1 to the center of the third subpixel F3.

[0330] The first distance L1 and the second distance L2 measured from the first side S1 or the extension line of the first side S1 may be the same. In this case, the first distance L1 may be the distance from one of the first side S1 and the extension line of the first side S1 to the short side of the second subpixel F2, and the second distance L2 may be the distance from one of the first side S1 and the extension line of the first side S1 to the short side of the third subpixel F3.

[0331] An outline R connecting a portion of an edge of the second subpixel F2 to a portion of an edge of the third subpixel F3 may have a square shape, with the second subpixel F2 and the third subpixel F3 facing one edge of the first subpixel F1. For example, outline R may be drawn by connecting the remaining edges of the second subpixel F2, excluding one edge of the second subpixel F2 and one edge of the third subpixel F3, to the remaining edges of the third subpixel F3 at a portion where the second subpixel F2 and the third subpixel F3 are spaced apart from each other, and by connecting a vertex of the second subpixel F2 to a vertex of the third subpixel F3, wherein the one edge of the second subpixel F2 and the one edge of the third subpixel F3 face each other, and the vertex of the second subpixel F2 and the vertex of the third subpixel F3 face each other. Outline R may be formed into a square shape such that the second subpixel F2 and the third subpixel F3 are arranged at the second side S2 in a mirror-image manner corresponding to the arrangement of the second subpixel F2 and the third subpixel F3 facing the first side S1.

[0332] The first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C, which respectively form the first subpixel F1, the second subpixel F2, and the third subpixel F3, can be formed and arranged in the same or similar manner as the first subpixel F1, the second subpixel F2, and the third subpixel F3, respectively. In this case, the centers of the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C can be arranged at the same or different positions as the centers of the first subpixel F1, the second subpixel F2, and the third subpixel F3, respectively. Here, the above description of the first subpixel F1, the second subpixel F2, and the third subpixel F3 can be applied to the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C, respectively.

[0333] The display device may include a barrier portion having a barrier layer 52. In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52 and may be arranged to be spaced apart from each other. Figure 4A and Figure 4B As described, each barrier layer 52 may be disposed on the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 .

[0334] Therefore, the display device can prevent or substantially prevent the moire phenomenon from being seen from outside the display device (eg, from an external environment) due to external light or operation of the display device.

[0335] The display device can be manufactured by an apparatus for manufacturing a display device. Here, the apparatus for manufacturing a display device can be manufactured with Figure 5 and Figure 6In this case, the first to third intermediate layers 28-2A to 28-2C can be formed by using masks having shapes similar to those of the first to third masks described above. The openings of each mask used in forming the first to third intermediate layers 28-2A to 28-2C can be formed to correspond to the shape of each intermediate layer.

[0336] Figure 22 is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments.

[0337] Reference Figure 22 , the display device can be connected with Figure 2A and Figure 2B The same as the display device shown in . In the display panel, a display area and a non-display area outside or around the display area can be defined throughout the substrate. In one or more embodiments, the non-display area surrounds the display area. Subpixels including a first subpixel F1, a second subpixel F2, and a third subpixel F3 can be arranged in the display area, and the power lines can be arranged in the non-display area. In one or more embodiments, the pad portion can be arranged in the non-display area. The display device may include a display substrate, an intermediate layer arranged in the display area, a counter electrode, and a thin film encapsulation layer.

[0338] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit light beams of different colors. For example, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit blue light, another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit red light, and yet another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit green light.

[0339] One of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a rectangular shape.

[0340] Hereinafter, for convenience of description, one or more embodiments in which the first subpixel F1 has a square shape and emits red light, the second subpixel F2 has a rectangular shape and emits green light, and the third subpixel F3 has a rectangular shape and emits blue light will be described in more detail.

[0341] The first sub-pixel F1 may include a first intermediate layer 28-2A, and the first intermediate layer 28-2A may correspond to the shape and position of the first sub-pixel F1. In this case, the planar area of ​​the first intermediate layer 28-2A may be greater than or equal to the planar area of ​​the first sub-pixel F1, and the region of the first sub-pixel F1 may be arranged in the region of the first intermediate layer 28-2A.

[0342] The second sub-pixel F2 may include a second intermediate layer 28-2B. In one or more embodiments, the second intermediate layer 28-2B may correspond to the shape and position of the second sub-pixel F2. In this case, the area of ​​the second sub-pixel F2 may be arranged in the area of ​​the second intermediate layer 28-2B.

[0343] The third sub-pixel F3 may include a third intermediate layer 28-2C. In one or more embodiments, the third intermediate layer 28-2C may correspond to the shape and position of the third sub-pixel F3. In this case, the area of ​​the third sub-pixel F3 may be arranged in the area of ​​the third intermediate layer 28-2C.

[0344] The planar area of ​​the second subpixel F2 may be different from the planar area of ​​the third subpixel F3. For example, one of the planar area of ​​the second subpixel F2 and the planar area of ​​the third subpixel F3 may be smaller than the other of the planar area of ​​the second subpixel F2 and the planar area of ​​the third subpixel F3. In one or more embodiments, the planar area of ​​the second subpixel F2 may be smaller than the planar area of ​​the third subpixel F3. In another embodiment, the planar area of ​​the third subpixel F3 may be smaller than the planar area of ​​the second subpixel F2. Therefore, the aperture ratio of light emitted from each subpixel may be adjustable.

[0345] As described above, the area of ​​at least one of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 can be adjusted by adjusting the area of ​​the exposed pixel electrode of the pixel defining layer. In this case, the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C formed by being deposited in the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, respectively, can have an area and shape corresponding to the area and shape of each sub-pixel to prevent or substantially prevent the sub-pixels from overlapping each other.

[0346] The display device may include a barrier portion having a barrier layer 52. In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52 and may be arranged to be spaced apart from each other. Figure 4A and Figure 4B As described, each barrier layer 52 may be disposed on the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 .

[0347] Therefore, the display device can prevent or substantially prevent the moire phenomenon from being seen from outside the display device (eg, from an external environment) due to external light or operation of the display device.

[0348] The display device can be manufactured by an apparatus for manufacturing a display device. Here, the apparatus for manufacturing a display device can be manufactured with Figure 5 and Figure 6 The display device can be formed similarly to the device for manufacturing a display device shown in . In this case, the first intermediate layer 28-2A to the third intermediate layer 28-2C can be formed by using a mask sheet having a shape similar to the shape of the first mask sheet to the third mask sheet described above. The opening of each mask sheet used in forming the first intermediate layer 28-2A to the third intermediate layer 28-2C can be formed to correspond to the shape of each intermediate layer. The display device can be fixed to a device for transporting a user, such as a vehicle. In this case, the display device can be fixed to the device so that a predetermined or set angle other than 0° is formed between the user's gaze direction and the first direction or the second direction. For example, the display device can be arranged so that a 90° angle is formed between the gaze direction of the user viewing the display device and the first direction or the second direction.

[0349] In the above case, when a user views the display device, the inclined portion of the pixel defining layer and the gaze direction are not perpendicular to each other, and therefore, external light may be reflected by the inclined portion of the pixel defining layer, and the external light may be prevented or substantially prevented from entering the user's eyes. In other words, the inclined portion may prevent or substantially prevent external light from being reflected into the user's eyes.

[0350] In one or more embodiments, the display device can achieve accurate images through each sub-pixel.

[0351] Figure 23 is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments.

[0352] Reference Figure 23 , the display device can be connected with Figure 2A and Figure 2B The same as the display device shown in . In the display panel, a display area and a non-display area outside or around the display area can be defined throughout the substrate. In one or more embodiments, the non-display area surrounds the display area. Subpixels including a first subpixel F1, a second subpixel F2, and a third subpixel F3 can be arranged in the display area, and the power lines can be arranged in the non-display area. In one or more embodiments, the pad portion can be arranged in the non-display area. The display device may include a display substrate, an intermediate layer arranged in the display area, a counter electrode, and a thin film encapsulation layer.

[0353] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit light beams of different colors. For example, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit blue light, another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit red light, and yet another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit green light.

[0354] One of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a rectangular shape.

[0355] Hereinafter, for convenience of description, one or more embodiments in which the first subpixel F1 has a square shape and emits red light, the second subpixel F2 has a rectangular shape and emits green light, and the third subpixel F3 has a rectangular shape and emits blue light will be described in more detail.

[0356] The first sub-pixel F1 may include a first intermediate layer 28-2A, and the first intermediate layer 28-2A may correspond to the shape and position of the first sub-pixel F1. In this case, the planar area of ​​the first intermediate layer 28-2A may be greater than or equal to the planar area of ​​the first sub-pixel F1, and the region of the first sub-pixel F1 may be arranged in the region of the first intermediate layer 28-2A.

[0357] The second sub-pixel F2 may include a second intermediate layer 28-2B. In one or more embodiments, the second intermediate layer 28-2B may correspond to the shape and position of the second sub-pixel F2. In this case, the area of ​​the second sub-pixel F2 may be arranged in the area of ​​the second intermediate layer 28-2B.

[0358] The third sub-pixel F3 may include a third intermediate layer 28-2C. In one or more embodiments, the third intermediate layer 28-2C may correspond to the shape and position of the third sub-pixel F3. In this case, the area of ​​the third sub-pixel F3 may be arranged in the area of ​​the third intermediate layer 28-2C.

[0359] In the above case, each of the second sub-pixel F2 and the third sub-pixel F3 may have various suitable planar areas.

[0360] In one or more embodiments, the planar areas of the second subpixels F2 may be different from each other. For example, the planar areas of some of the second subpixels F2 may be different from the planar areas of other second subpixels F2. Specifically, a pair of second subpixels F2 that face one first subpixel F1 and are adjacent to each other may have different planar areas.

[0361] In one or more embodiments, the planar areas of the third subpixels F3 may be different from each other. For example, the planar areas of some of the third subpixels F3 may be different from the planar areas of other third subpixels F3. Specifically, third subpixels F3 that face one first subpixel F1 and are adjacent to each other may have different planar areas.

[0362] In the above case, the distances from one of the first side S1 and the second side S2 of the first subpixel F1 or from the extension line of the first side S1 or the second side S2 of the first subpixel F1 to the second subpixel F2 and the third subpixel F3 facing one of the first side S1 and the second side S2 may be different from each other.

[0363] For example, with respect to the second subpixel F2 and the third subpixel F3 facing the first side S1 or the extension line of the first side S1, the first distance L1, which is the shortest distance from the first side S1 or the extension line of the first side S1 to the short side of the second subpixel F2 (or one side of the second subpixel F2 or the center of the second subpixel F2), may be different from the second distance L2, which is the shortest distance from the first side S1 or the extension line of the first side S1 to the short side of the third subpixel F3 (or one side of the third subpixel F3 or the center of the third subpixel F3). Specifically, the first distance L1 may be longer than the second distance L2.

[0364] For example, with respect to the second subpixel F2 and the third subpixel F3 facing the second side S2 or the extension line of the second side S2, the third distance L3, which is the shortest distance from the second side S2 or the extension line of the second side S2 to the short side of the second subpixel F2 (or one side of the second subpixel F2 or the center of the second subpixel F2), may be different from the fourth distance L4, which is the shortest distance from the second side S2 or the extension line of the second side S2 to the short side of the third subpixel F3 (or one side of the third subpixel F3 or the center of the third subpixel F3). Specifically, the third distance L3 may be shorter than the fourth distance L4.

[0365] In another embodiment, the planar areas of the second subpixels F2 may be the same, and the planar areas of the third subpixels F3 may be the same. In this case, the planar area of ​​each second subpixel F2 may be greater than or less than the planar area of ​​each third subpixel F3. In the above case, in one or more embodiments, a pair of third subpixels F3 may be arranged between a pair of second subpixels F2 arranged to face the first side S1 and the second side S2, respectively, so as to face the first side S1 and the second side S2, respectively. In this case, the shortest distance from the first side S1 or the second side S2 to the short side of the second subpixel F2 (or one side of the second subpixel F2 or the center of the second subpixel F2) may be less than the shortest distance from the first side S1 or the second side S2 to the short side of the third subpixel F3 (or one side of the third subpixel F3 or the center of the third subpixel F3). In another embodiment, a pair of second subpixels F2 may be arranged between a pair of third subpixels F3 arranged to face the first side S1 and the second side S2, respectively, so as to face the first side S1 and the second side S2, respectively. In this case, the shortest distance from the first side S1 or the second side S2 to the short side of the second subpixel F2 (or one side of the second subpixel F2 or the center of the second subpixel F2) can be greater than the shortest distance from the first side S1 or the second side S2 to the short side of the third subpixel F3 (or one side of the third subpixel F3 or the center of the third subpixel F3).

[0366] Hereinafter, for the convenience of description, one or more embodiments in which the planar areas of some of the second sub-pixels F2 in the second sub-pixels F2 are different from the planar areas of other second sub-pixels F2 in the second sub-pixels F2, the planar areas of some of the third sub-pixels F3 in the third sub-pixels F3 are different from the planar areas of other third sub-pixels F3 in the third sub-pixels F3, the first distance L1 is different from the second distance L2, and the third distance L3 is different from the fourth distance L4 will be described in more detail.

[0367] The spacer P may be arranged between the sub-pixels. Figure 3 The spacers P shown in FIG. 1 are the same or similar.

[0368] The first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may be arranged in the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, respectively, to correspond to the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, respectively. In this case, the relationship between the first intermediate layer 28-2A, the second intermediate layer 28-2B, and the third intermediate layer 28-2C may be the same as the relationship between the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3.

[0369] For example, the centers of some of the second subpixels F2 may be arranged in a straight line in one direction, and the centers of other of the second subpixels F2 may be arranged in a serpentine form in another direction. In one or more embodiments, the centers of some of the third subpixels F3 may be arranged in a straight line in one direction, and the centers of other of the third subpixels F3 may be arranged in a serpentine form in another direction. The centers of the first subpixels F1 may be arranged in a straight line in a direction different from the one direction.

[0370] In one or more embodiments, the second subpixel F2 and the third subpixel F3 facing the same first subpixel F1 can be tilted in opposite directions relative to the stretching direction of the second mask sheet and the stretching direction of the third mask sheet. Specifically, in this case, the adjacent second subpixels F2 can form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet in the opposite directions. Furthermore, the second openings formed in the second mask sheet and adjacent to each other can also form an angle of 45° or approximately 45° relative to the stretching direction of the second mask sheet. Adjacent third subpixels F3 can also form an angle of 45° or approximately 45° relative to the stretching direction of the third mask sheet in the opposite directions. Furthermore, the third openings formed in the third mask sheet and adjacent to each other can also form an angle of 45° or approximately 45° relative to the stretching direction of the third mask sheet. In this case, the second intermediate layer 28-2B and the third intermediate layer 28-2C can be arranged on the substrate to correspond to the positions corresponding to the second openings and the third openings, respectively.

[0371] The display device may include a device having ( Figure 1C or Figure 1B In this case, the barrier layer 52 may be provided as a plurality of barrier layers 52 and may be arranged to be spaced apart from each other. Figure 4A and Figure 4B As described, each barrier layer 52 may be disposed on the first sub-pixel F1 , the second sub-pixel F2 , and the third sub-pixel F3 .

[0372] Therefore, the display device can prevent or substantially prevent the moire phenomenon from being seen from outside the display device (eg, from an external environment) due to external light or operation of the display device.

[0373] The display device can be manufactured by an apparatus for manufacturing a display device. Here, the apparatus for manufacturing a display device can be manufactured with Figure 5 and Figure 6In this case, the first to third intermediate layers 28-2A to 28-2C can be formed by using masks having shapes similar to those of the first to third masks described above. The openings of each mask used in forming the first to third intermediate layers 28-2A to 28-2C can be formed to correspond to the shape of each intermediate layer.

[0374] Figure 24 is a plan view illustrating a first subpixel F1, a second subpixel F2, and a third subpixel F3 of a display device according to one or more embodiments.

[0375] Reference Figure 24 , the display device can be connected with Figure 2A and Figure 2B The same as the display device shown in . In the display panel, a display area and a non-display area outside or around the display area can be defined throughout the substrate. In one or more embodiments, the non-display area surrounds the display area. Subpixels including a first subpixel F1, a second subpixel F2, and a third subpixel F3 can be arranged in the display area, and the power lines can be arranged in the non-display area. In one or more embodiments, the pad portion can be arranged in the non-display area. The display device may include a display substrate, an intermediate layer arranged in the display area, a counter electrode, and a thin film encapsulation layer.

[0376] The first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit light beams of different colors. For example, one of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit blue light, another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit red light, and yet another of the first subpixel F1, the second subpixel F2, and the third subpixel F3 may emit green light.

[0377] One of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a square shape, and the other two of the first subpixel F1 , the second subpixel F2 , and the third subpixel F3 may have a rectangular shape.

[0379] The first sub-pixel F1 may include a first intermediate layer 28-2A, and the first intermediate layer 28-2A may correspond to the shape and position of the first sub-pixel F1. In this case, the planar area of ​​the first intermediate layer 28-2A may be larger than the planar area of ​​the first sub-pixel F1, and the region of the first sub-pixel F1 may be arranged in the region of the first intermediate layer 28-2A.
