[0036] In the following description, for the purpose of explanation, many specific details are set forth in order to provide a thorough understanding of various embodiments or implementations of the present disclosure. As used herein, "embodiment" and "implementation" are interchangeable words, which are non-limiting examples of the devices or methods disclosed herein. However, it is apparent that various embodiments can be practiced without these specific details or in the case of one or more equivalent arrangements. Here, various embodiments do not have to be exclusive, nor do they have to limit the present disclosure. For example, the specific shape, configuration, and characteristics of an embodiment can be used or implemented in another embodiment.

[0037] Unless otherwise specified, the embodiments shown should be understood to provide features of the present disclosure. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects of various embodiments, etc. (hereinafter referred to individually or collectively as "elements") may be combined, separated, interchanged and / or rearranged in other ways without departing from the present disclosure.

[0038] Reference will now be made in detail to the embodiments of which examples are shown in the accompanying drawings, in which like reference numerals refer to like elements throughout. In this regard, the embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the following merely explains various aspects of the description by describing the embodiments with reference to the drawings.

[0039] The technical terms used herein are for the purpose of describing specific embodiments and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" as used herein are also intended to include the plural forms. In addition, when the terms "comprise", "comprising", "include" and / or "including" are used in this specification, the existence of the stated features, integers, steps, operations, elements, parts and / or clusters thereof is explained, but the existence or addition of one or more other features, integers, steps, operations, elements, parts and / or clusters thereof is not excluded. It should also be noted that, as used herein, the terms "substantially", "about" and other similar terms are used as approximate terms and are not used as terms of degree, and thus, are utilized to take into account the inherent deviations of measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0040] Although the terms "first", "second", etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, without departing from the teachings of the present disclosure, the first element discussed below can be referred to as the second element.

[0041] When an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it may be directly on, directly connected to, or coupled to another element or layer, or there may be intervening elements or layers. However, when an element or layer is referred to as being "directly" "on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers. For this purpose, the term "connected" may refer to a physical, electrical, and / or fluid connection with or without intervening elements. In addition, the x-axis direction, the y-axis direction, and the z-axis direction are not limited to the three axes of a rectangular coordinate system, and may be interpreted in a broader sense. For example, the x-axis direction, the y-axis direction, and the z-axis direction may be perpendicular to each other, or may represent different directions that are not perpendicular to each other.

[0042] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "over" another element, the element can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements.

[0043] Spatially relative terms (such as "above", "on", "above" and the like) may be used herein for descriptive purposes, and thereby describe the relationship of one element to another element as shown in the accompanying drawings. In addition to the orientations depicted in the accompanying drawings, spatially relative terms are also intended to cover different orientations of the device in use, operation and / or manufacture. For example, if the device in the accompanying drawings is flipped, the element described as being "below" or "below" other elements or features will then be oriented "above" the other elements or features. Therefore, the exemplary term "below" can cover both the orientations of above and below. In addition, the device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations), and thus, the spatially relative descriptors used herein are interpreted accordingly.

[0044] When a component is described herein as being “connected” to another component or “connected to” another component, the components may be connected to each other as separate elements, or the components may be integral with each other.

[0045] Throughout the specification, when an element is referred to as being “connected” to another element, the element may be “directly connected” to the other element, or “electrically connected” to the other element with one or more intervening elements interposed therebetween. Also, when an element is referred to as being “in contact with” or the like with another element, the element may be “electrically in contact with” or “physically in contact with” the other element, or “indirectly in contact with” or “directly in contact with” the other element.

[0046] As used herein, the term "and / or" includes any and all combinations of at least one of the associated listed items. For example, "a and / or b" may be understood to mean "a, b, or a and b". The terms "and" and "or" may be used in conjunction or disjunction and may be understood to be equivalent to "and / or". Throughout the disclosure, the expression "at least one of a, b, and c" indicates 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 variations thereof. Furthermore, "at least two of x, y, and z" may be interpreted as two or more of x, y, and z, such as both x and y, both x and z, both y and z, all of x, y, and z.

[0047] Since various modifications and various embodiments of the present disclosure are possible, specific embodiments are shown in the drawings and described in detail in the detailed description. The effects and features of the present disclosure and methods for achieving them will be apparent with reference to the embodiments described in detail below in conjunction with the drawings. However, the present disclosure is not limited to the embodiments disclosed herein, but can be implemented in various forms.

[0048] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, and the same or corresponding components are denoted by the same reference numerals and assigned the same reference numerals and redundant explanations will be omitted.

[0049] In the following embodiments, when a part such as a layer, a film, a region, a plate or the like is on other parts, this is not only when the part is on other parts, but also when other elements are interposed therebetween. In the accompanying drawings, the size of the elements may be exaggerated or reduced for the convenience of explanation. For example, since the size and thickness of each component shown in the drawings are arbitrarily indicated for the convenience of explanation, the present disclosure is not necessarily limited to the drawings.

[0050] The use of cross hatching and / or shading in the drawings is generally provided to clarify the boundaries between adjacent elements. Thus, unless otherwise specified, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, ratio, commonality between the elements shown, and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the drawings, the size and relative size of the elements may be exaggerated for clarity and / or descriptive purposes. When the embodiment can be implemented differently, the specific process sequence can be performed differently from the described sequence. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described order. Moreover, similar reference numerals represent similar elements.

[0051] Various embodiments are described herein with reference to cross-sectional illustrations and / or exploded illustrations that are schematic illustrations of embodiments and / or intermediate structures. Thus, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are to be expected. Therefore, the embodiments disclosed herein should not necessarily be construed as limited to the shapes of the particular illustrated regions, but rather include deviations in shape due to, for example, manufacturing. In this way, the regions shown in the drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and thus, are not necessarily intended to be limiting.

[0052] The x-axis, y-axis, and z-axis are not limited to the three axes on the Cartesian coordinate system, and may include a broad interpretation thereof. For example, the x-axis, y-axis, and z-axis may not be perpendicular to each other, but may refer to different directions that are not orthogonal to each other.

[0053] The display surface may be parallel to the surface defined by the x-axis direction and the y-axis direction. The normal direction of the display surface (i.e., the thickness direction of the display device) may indicate the z-axis direction. In this specification, the expression "when viewed from the top or in a plan view" may represent the situation when viewed in the z-axis direction. In the following, the front surface (or top surface) and the rear surface (or bottom surface) of each of the multiple layers or multiple units may be distinguished by the z-axis direction. However, the directions indicated by the x-axis direction, the y-axis direction, and the z-axis direction may be relative concepts and may be converted relative to each other, for example, converted to the opposite direction.

[0054] Unless otherwise defined or implied herein, all terms (including technical and scientific terms) used have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. It will also be understood that, unless clearly defined in the specification, terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and should not be interpreted in an idealized or overly formal sense.

[0055] Hereinafter, a display device according to an embodiment will be described in detail based on the above description, as follows.

[0056] Figure 1 is a schematic plan view showing a display panel of a display device according to an embodiment.

[0057] like Figure 1 As shown in , a display device according to an embodiment may include a display panel 10. For example, the display device may be various devices such as a smart phone, a tablet computer, a laptop computer, a television, a billboard, or the like. A display device according to an embodiment may include a thin film transistor, a capacitor, and / or the like, and the thin film transistor, the capacitor, and / or the like may be implemented by a conductive layer and an insulating layer.

[0058] The display panel 10 may include a display area DA and a peripheral area PA disposed adjacent to the display area DA. For example, in a plan view, the peripheral area PA may surround the display area DA. Figure 1 The display area DA is shown to have a rectangular shape in a plan view. However, the present disclosure is not limited thereto. The display area DA may have various shapes in a plan view, such as a circular shape, an elliptical shape, another polygonal shape, a shape of a specific figure, and the like.

[0059] The display area DA may be a portion where an image is displayed, and a plurality of pixels PX may be arranged in the display area DA. Each of the pixels PX may include a display element such as an organic light emitting diode or the like. For example, each pixel PX may emit red light, green light, or blue light. The display element may be electrically connected to a pixel circuit including a thin film transistor (TFT), a storage capacitor, and the like. The pixel circuit may be electrically connected to a scan line SL that transmits a scan signal, a data line DL that intersects the scan line SL and transmits a data signal, and a drive voltage line PL that supplies a drive voltage. The scan line SL may extend in an x-axis direction (hereinafter, a second direction), and the data line DL and the drive voltage line PL may extend in a y-axis direction (hereinafter, a first direction).

[0060] The pixel PX may emit light having a brightness corresponding to an electrical signal from a pixel circuit electrically connected to the display element. In the display area DA, an image (e.g., a certain or selectable image) may be displayed by light emitted from the pixel PX. In an embodiment, as described above, the pixel PX may be a light emitting area that emits light of one color of red, green, and blue.

[0061] The peripheral area PA may be an area where pixels PX are not arranged and an area where no image is displayed. Power wiring for driving the pixels PX may be arranged in the peripheral area PA. A plurality of pads may be arranged in the peripheral area PA, and a printed circuit board or an integrated circuit (IC) element including a driving circuit portion (such as a driver IC or the like) may be arranged in the peripheral area PA and electrically connected to the pads.

[0062] The display panel 10 may include a substrate 100, and the substrate 100 may include a display area DA and a peripheral area PA. The substrate 100 will be described in detail below.

[0063] A plurality of transistors may be arranged in the display area DA. In the transistor, the first terminal of the transistor may be one of the source electrode and the drain electrode, and the second terminal of the transistor may be the other of the source electrode and the drain electrode, depending on the type (N-type or P-type) of the transistor and / or operating conditions. For example, in the case where the first terminal is a source electrode, the second terminal may be a drain electrode.

[0064] The plurality of transistors may include a driving transistor, a data writing transistor, a compensation transistor, an initialization transistor, an emission control transistor, or the like. The driving transistor may be electrically connected between a driving voltage line PL and an organic light emitting diode (see, for example, Figure 2 The data line DL and the driving transistor may be electrically connected between the data line DL and the organic light emitting diode OLED and may perform a switching operation for transmitting a data signal transmitted from the data line DL.

[0065] The compensation transistor may be turned on in response to a scan signal received through the scan line SL and diode-connect the driving transistor, thereby compensating for a threshold voltage of the driving transistor.

[0066] The initialization transistor may be turned on in response to a scan signal received through the scan line SL and transmit an initialization voltage to the gate electrode of the driving transistor, thereby initializing the gate electrode of the driving transistor. The scan line SL electrically connected to the initialization transistor and the scan line SL electrically connected to the compensation transistor may be different from each other.

[0067] The emission control transistor may be turned on in response to an emission control signal received through the emission control line, and as a result, a driving current may flow through the organic light emitting diode OLED.

[0068] The organic light emitting diode OLED may include a pixel electrode (anode) and an opposite electrode (cathode), and a second power supply voltage ELVSS (eg, reference Figure 2 ) may be applied to the opposing electrodes (see e.g. Figure 3 The organic light emitting diode OLED may receive a driving current from the driving transistor and emit light, thereby displaying an image.

[0069] In the following, an organic light-emitting display device is described as a display device according to an embodiment.

The switching thin film transistor Ts may be electrically connected to the scan line SL and the data line DL, and may transmit a data signal Dm input through the data line DL to the driving thin film transistor Td in response to a scan signal Sn input through the scan line SL.

[0074] The storage capacitor Cst may be electrically connected to the switching thin film transistor Ts and the driving voltage line PL, and may store a voltage corresponding to a difference between a voltage transferred from the switching thin film transistor Ts and a first power source voltage ELVDD supplied through the driving voltage line PL.

[0075] The second power voltage ELVSS may be lower than the first power voltage ELVDD. A level of the driving voltage supplied to each pixel PX may be a voltage difference between a level of the first power voltage ELVDD and a level of the second power voltage ELVSS.

[0076] The driving thin film transistor Td may be electrically connected to the driving voltage line PL and the storage capacitor Cst, and may control a driving current flowing from the driving voltage line PL to the organic light emitting diode OLED in response to a voltage value stored in the storage capacitor Cst. The organic light emitting diode OLED may emit light having a brightness (e.g., a certain or selectable brightness) according to the driving current.

The buffer layer 101 may prevent diffusion of impurity ions, may prevent penetration of moisture or external air, and may be used as a barrier layer and / or a blocking layer for planarizing a surface (e.g., a top surface of the buffer layer 101). The buffer layer 101 may include silicon oxide, silicon nitride, silicon oxynitride, the like, or a combination thereof.

The semiconductor layer 110 may include polysilicon or the like, and may include a channel region not doped with impurities, and a source region and a drain region each disposed at one side of the channel region and doped with impurities. The impurities may vary depending on the type of the thin film transistor, and may be N-type impurities or P-type impurities.

The gate insulating layer 102 may ensure the insulating properties between the semiconductor layer 110 and the gate layer 120 (e.g., the first gate layer 120a). The gate insulating layer 102 may include an inorganic material such as silicon oxide, silicon nitride, silicon oxynitride, the like, or a combination thereof, and may be arranged between the semiconductor layer 110 and the gate layer 120.

[0096] The spacer 80 may be arranged in the peripheral area PA, but may also be arranged in the display area DA. The spacer 80 may prevent the organic light emitting diode OLED from being damaged due to sagging of the mask during a manufacturing process using the mask. The spacer 80 may include an organic insulating material or the like, and may have a single-layer or multi-layer structure.

[0097] The intermediate layer 160 and the opposite electrode 170 may be arranged in the opening of the pixel defining layer 106. The intermediate layer 160 may include a low molecular weight material, a polymer material, or the like, and in the case where the intermediate layer 160 includes a low molecular weight material, the intermediate layer 160 may include a hole injection layer (HIL), a hole transport layer (HTL), an emission layer, an electron transport layer (ETL), an electron injection layer (EIL), the like, or a combination thereof.

In another embodiment, the polarity of the electrodes may be reversed. For example, the pixel electrode 150 may be a cathode, and the counter electrode 170 may be an anode.

[0099] The structure of the intermediate layer 160 is not limited to the above description, and may have various structures. For example, as in the opposite electrode 170, at least one of the layers forming the intermediate layer 160 may be integrally formed. In another embodiment, the intermediate layer 160 may include a patterned layer corresponding to each of the pixel electrodes 150.

[0100] The opposing electrode 170 may be arranged in the display area DA and may be arranged throughout the entire display area DA. For example, the opposing electrode 170 may be integrally formed and cover a plurality of pixels (see, for example, Figure 2 The opposing electrode 170 may electrically contact a common power line (not shown) arranged in the peripheral area PA. In an embodiment, the opposing electrode 170 may extend to the barrier rib 200. The thin film encapsulation layer TFE may cover the entirety of the display area DA, may extend to the peripheral area PA, and may cover at least a portion of the peripheral area PA.

[0101] The thin film encapsulation layer TFE may extend to the outside of the common power line (not shown). The thin film encapsulation layer TFE may include a first inorganic encapsulation layer 310, a second inorganic encapsulation layer 330, and an organic encapsulation layer 320 between the first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330. The first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330 may include at least one inorganic material of aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and silicon oxynitride.

[0102] The first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330 may have a single-layer or multi-layer structure. The first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330 may include the same material or different materials. The thickness of the first inorganic encapsulation layer 310 and the thickness of the second inorganic encapsulation layer 330 may be different from each other. The thickness of the first inorganic encapsulation layer 310 may be greater than the thickness of the second inorganic encapsulation layer 330. In another embodiment, the thickness of the second inorganic encapsulation layer 330 may be greater than the thickness of the first inorganic encapsulation layer 310, or the thickness of the first inorganic encapsulation layer 310 and the thickness of the second inorganic encapsulation layer 330 may be the same.

[0103] The organic encapsulation layer 320 may include a monomer-based material or a polymer-based material. The polymer-based material may include acryl-based resin, epoxy-based resin, polyimide, polyethylene, the like, or a combination thereof. In an embodiment, the organic encapsulation layer 320 may include acrylate or the like.

[0105] In an embodiment, the barrier 200 may include only a portion 230 of the second organic insulating layer 105 or a portion 220 of the pixel defining layer 106. The barrier 200 may surround the display area DA and may prevent the organic encapsulation layer 320 of the thin film encapsulation layer TFE from overflowing to the outside of the substrate 100. The organic encapsulation layer 320 may contact a surface (e.g., an inner surface) of the barrier 200 facing the display area DA. With reference to the organic encapsulation layer 320 contacting the inner surface of the barrier 200, it is understood that the first inorganic encapsulation layer 310 is arranged between the organic encapsulation layer 320 and the barrier 200, and the organic encapsulation layer 320 contacts the first inorganic encapsulation layer 310.

[0106] The first and second inorganic encapsulating layers 310 and 330 may be disposed on the barrier ribs 200 and may extend to the edge of the substrate 100. However, in an embodiment, a plurality of barrier ribs 200 may be included in the display panel 10.

[0107] Figure 4 It is shown Figure 1 Schematic plan view of a sub-pixel in region A.

[0108] For convenience of explanation, the description will focus on the sub-pixels arranged in region A, and description of other components will be omitted. Figure 4 are plan views and unless otherwise requested, Figure 4 The description can be understood as being based on a plan view.

[0109] like Figure 4 As shown in, a display device according to an embodiment may include a plurality of reference sub-pixels BX1 to BX6 and a plurality of sub-pixels SPX1 to SPX4 in a plan view. The display device may include a plurality of reference sub-pixels and a first sub-pixel SPX1 and a second sub-pixel SPX2. The plurality of reference sub-pixels BX1 to BX6 may include a first reference sub-pixel BX1, a second reference sub-pixel BX2, an nth reference sub-pixel, and similar reference sub-pixels. For the convenience of explanation, a description will be provided based on some reference sub-pixels.

[0110] As the plurality of sub-pixels, the display device may further include a third sub-pixel SPX3, a fourth sub-pixel SPX4, an nth sub-pixel, and the like. The first to fourth sub-pixels SPX1 to SPX4 may be arranged in a diamond form with the first reference sub-pixel BX1 as the center.

[0111] The plurality of reference subpixels BX1 to BX6 may emit light in the first wavelength band and may have a polygonal shape in a plan view. As described above, the plurality of reference subpixels BX1 to BX6 may include a first reference subpixel BX1, a second reference subpixel BX2, and similar reference subpixels.

[0112] The first reference sub-pixel BX1 may be a sub-pixel that emits light in a first wavelength band. For example, the first reference sub-pixel BX1 may be a sub-pixel that emits light in a wavelength band of green light. The first reference sub-pixel BX1 may have a polygonal shape including a plurality of lines in a plan view. For example, the polygonal shape of the first reference sub-pixel BX1 in a plan view may include at least one obtuse angle and may be a polygonal shape including a line having a first length and a line having a second length. The first length may be greater than the second length.

[0113] like Figure 4 As shown in , the first reference subpixel BX1 may have a polygonal shape including a major axis and a minor axis intersecting (e.g., substantially perpendicularly intersecting) the major axis in a plan view. In a plan view, the polygonal shape of the first reference subpixel BX1 may have a major axis and a minor axis intersecting the major axis, and may be a polygonal shape having at least one obtuse angle.

[0114] For example, the first reference subpixel BX1 may have an octagonal shape including a major axis and a minor axis in a plan view. In the first reference subpixel BX1, a plurality of corners constituting the octagonal shape may have obtuse angles. Figure 4 , for convenience of explanation, in the reference sub-pixel corresponding to the first reference sub-pixel BX1, the major axis Lx and the minor axis Sx are indicated. However, the description of the major axis Lx and the minor axis Sx may be similarly applied to the others of the reference sub-pixels BX1 to BX6.

[0115] The first sub-pixel SPX1 may be a sub-pixel that emits light in a second wavelength band. For example, the first sub-pixel SPX1 may be a sub-pixel that emits light in a wavelength band of blue light. The first sub-pixel SPX1 may include a plurality of corners and a plurality of lines that connect the corners in a plan view. In a display device according to an embodiment, the first sub-pixel SPX1 may be spaced apart from the first reference sub-pixel BX1 at equal intervals in a plan view. In a plan view, the first sub-pixel SPX1 may be spaced apart from the first reference sub-pixel BX1 at a distance (e.g., a certain or selectable distance) R evenly.

[0116] The second sub-pixel SPX2 may be a sub-pixel that emits light in the third wavelength band. For example, the second sub-pixel SPX2 may be a sub-pixel that emits light in a wavelength band having red light. However, the present disclosure is not limited thereto, and in an embodiment, the third wavelength band and the first wavelength band or the second wavelength band may have substantially the same or similar ranges.

[0117] The second sub-pixel SPX2 may include a plurality of corners and a plurality of lines connecting the corners in a plan view. In a display device according to an embodiment, the second sub-pixel SPX2 may be spaced apart from the first reference sub-pixel BX1 at an equal interval in a plan view. The second sub-pixel SPX2 may be spaced apart from the first reference sub-pixel BX1 at a distance (e.g., a certain or selectable distance) R in a plan view.

[0118] For an organic light emitting element that emits light in a wavelength band of blue light, a relatively short lifespan may be a problem, and generally, an area of ​​the first subpixel SPX1 may be larger than an area of ​​the second subpixel SPX2 in a plan view.

[0119] The display device may further include a display device based on a first imaginary axis (see, e.g. Figure 5 The second reference sub-pixel BX2 may be symmetrical to the first reference sub-pixel BX1 in a plan view, except that the second reference sub-pixel BX2 has a shape symmetrical to the first reference sub-pixel BX1 in a plan view. The first imaginary axis Vx1 will be described below. The second reference sub-pixel BX2 and the first reference sub-pixel BX1 may have the same features, except that the second reference sub-pixel BX2 has a shape symmetrical to the first reference sub-pixel BX1 in a plan view.

[0120] The third subpixel SPX3 may be symmetrical to the first subpixel SPX1 based on the major axis of the first reference subpixel BX1. The third subpixel SPX3 and the first subpixel SPX1 may have the same features except that the third subpixel SPX3 has a symmetrical shape to the first subpixel SPX1 in a plan view.

[0121] The fourth subpixel SPX4 may be symmetrical to the second subpixel SPX2 based on the short axis of the first reference subpixel BX1. The fourth subpixel SPX4 and the second subpixel SPX2 may have the same features except that the fourth subpixel SPX4 has a symmetrical shape to the second subpixel SPX2 in a plan view.

[0122] The first reference subpixel BX1 may be spaced apart from the first subpixel SPX1 and the second subpixel SPX2 by a distance (e.g., a certain or selectable distance) R. The other subpixels SPX3 and SPX4 except the first subpixel SPX1 and the second subpixel SPX2 may be spaced apart from the first reference subpixel BX1 by a distance (e.g., a certain or selectable distance) R. For example, at least four subpixels (e.g., subpixels SPX1 to SPX4) may be arranged around the first reference subpixel BX1 and spaced apart from the first reference subpixel BX1 by a distance (e.g., a certain or selectable distance) R. For example, at least four subpixels (e.g., subpixels SPX1 to SPX4) may be arranged around the first reference subpixel BX1 at equal intervals.

[0123] Figure 5 It is shown Figure 4Schematic plan view of a sub-pixel in area A1.

[0124] For convenience of explanation, the description will focus on the sub-pixels arranged in the area A1, and description of other components may be omitted. Figure 5 are plan views and unless otherwise requested, Figure 5 The description can be understood as being based on a plan view.

[0125] like Figure 5 As shown in , the polygonal shape of the first reference sub-pixel BX1 may include at least one obtuse angle, a 1-1 line segment b1, and a 1-2 line segment b2. The 1-1 line segment b1 may have a first length, the 1-2 line segment b2 may have a second length, and the first length may be greater than or equal to the second length. The second length may be less than the first length. The 1-1 line segment b1 may be parallel to the long axis of the first reference sub-pixel BX1 in a plan view, and the 1-2 line segment b2 may be parallel to the short axis of the first reference sub-pixel BX1 in a plan view.

[0126] The polygonal shape of the first reference subpixel BX1 in a plan view may include a 1-1 line segment b1, a 1-2 line segment b2, a 1-3 line segment b3, and a 1-4 line segment b4. The first reference subpixel BX1 may include a 1-1 hypotenuse segment b12 connecting the 1-1 line segment b1 and the 1-2 line segment b2 to each other, a 1-2 hypotenuse segment b23 connecting the 1-2 line segment b2 and the 1-3 line segment b3 to each other, a 1-3 hypotenuse segment b34 connecting the 1-3 line segment b3 and the 1-4 line segment b4 to each other, and a 1-4 hypotenuse segment b41 connecting the 1-4 line segment b4 and the 1-1 line segment b1 to each other.

[0127] However, the present disclosure is not limited thereto, and according to design, the first reference subpixel BX1 may include or omit at least one line segment, and may include or omit at least one oblique edge segment.

[0128] The extension line of the 1-1 line segment b1 and the extension line of the 1-2 line segment b2 may intersect each other (e.g., intersect approximately perpendicularly). The 1-1 line segment b1 and the 1-3 line segment b3 may be arranged parallel to each other in a plan view. The 1-2 line segment b2 and the 1-4 line segment b4 may be arranged parallel to each other in a plan view. The extension line of the 1-3 line segment b3 and the extension line of the 1-4 line segment b4 may also intersect each other (e.g., intersect approximately perpendicularly).

[0129] For example, the line segments arranged in parallel with the long axis in the first reference subpixel BX1 (e.g., the 1-1 line segment b1, the 1-3 line segment b3) may have the first length described above, and the line segments arranged in parallel with the short axis (e.g., the 1-2 line segment b2, the 1-4 line segment b4) may have the second length described above. The line segments having the first length and the line segments having the second length may be connected by a line segment having a third length (e.g., the 1-1 hypotenuse segment b12 to the 1-4 hypotenuse segment b41). The third length may be smaller than the first length. The third length and the second length may be the same, or the third length may be smaller than the second length.

[0130] However, the present disclosure is not limited thereto, and the shape of the first reference subpixel BX1 may vary according to design. The lengths of the 1-1st line segment b1 and the 1-3rd line segment b3 may be different from each other, the lengths of the 1-2nd line segment b2 and the 1-4th line segment b4 may be different from each other, and the lengths of the oblique side segments (e.g., the 1-1st oblique side segment b12 and the 1-3rd oblique side segment b34, the 1-2nd oblique side segment b23 and the 1-4th oblique side segment b41) may also be different from each other.

[0131] The second reference subpixel BX2 may be symmetrical to the first reference subpixel BX1 based on a first imaginary axis Vx1 extending in the y-axis direction. The first imaginary axis Vx1 may be an imaginary axis extending through the center of the first subpixel SPX1 and the center of the second subpixel SPX2. The second imaginary axis Vx2 may intersect the first imaginary axis Vx1. The second imaginary axis Vx2 may be an imaginary axis extending in the x-axis direction.

[0132] like Figure 5 As shown in , the polygonal shape of the second reference sub-pixel BX2 may include at least one obtuse angle, the 2-1 line segment b1' and the 2-2 line segment b2'. The 2-1 line segment b1' may have a first 'length, the 2-2 line segment b2' may have a second 'length, and the first 'length may be greater than or equal to the second 'length. The second 'length may be less than the first 'length. The 2-1 line segment b1' may be parallel to the long axis of the second reference sub-pixel BX2 in a plan view, and the 2-2 line segment b2' may be parallel to the short axis of the second reference sub-pixel BX2 in a plan view.

[0133] The polygonal shape of the second reference subpixel BX2 in a plan view may include a 2-1st line segment b1', a 2-2nd line segment b2', a 2-3rd line segment b3', and a 2-4th line segment b4'. The second reference subpixel BX2 may include a 2-1st hypotenuse segment b12' connecting the 2-1st line segment b1' and the 2-2nd line segment b2' to each other, a 2-2nd hypotenuse segment b23' connecting the 2-2nd line segment b2' and the 2-3rd line segment b3' to each other, a 2-3rd hypotenuse segment b34' connecting the 2-3rd line segment b3' and the 2-4th line segment b4' to each other, and a 2-4th hypotenuse segment b41' connecting the 2-4th line segment b4' and the 2-1st line segment b1' to each other.

[0134] However, according to design, the second reference sub-pixel BX2 may include or omit at least one other line segment, and may include or omit at least one other oblique edge segment.

[0135] The extension line of the 2-1st line segment b1' and the extension line of the 2-2nd line segment b2' may intersect each other (e.g., intersect approximately perpendicularly). The 2-1st line segment b1' and the 2-3rd line segment b3' may be arranged parallel to each other in a plan view. The 2-2nd line segment b2' and the 2-4th line segment b4' may be arranged parallel to each other in a plan view. The extension line of the 2-3rd line segment b3' and the extension line of the 2-4th line segment b4' may also intersect each other (e.g., intersect approximately perpendicularly).

[0136] For example, the line segments arranged in parallel with the major axis in the second reference subpixel BX2 (e.g., the 2-1st line segment b1', the 2-3rd line segment b3') may have the first 'length described above, and the line segments arranged in parallel with the minor axis (e.g., the 2-2nd line segment b2', the 2-4th line segment b4') may have the second 'length described above. The line segments having the first 'length and the line segments having the second 'length may be connected by line segments having the third 'length (e.g., the 2-1st hypotenuse segment b12' to the 2-4th hypotenuse segment b41'). The size of the third 'length may be smaller than the size of the first 'length. The size of the third 'length may be the same as the size of the second 'length, or the size of the third 'length may be smaller than the size of the second 'length.

[0137] However, the shape of the second reference subpixel BX2 may vary according to design. The lengths of the 2-1st line segment b1' and the 2-3rd line segment b3' may be different from each other, the lengths of the 2-2nd line segment b2' and the 2-4th line segment b4' may be different from each other, and the lengths of the oblique side segments (e.g., the 2-1st oblique side segment b12' and the 2-3rd oblique side segment b34', the 2-2nd oblique side segment b23' and the 2-4th oblique side segment b41') may also be different from each other.

[0138] like Figure 5As shown in , the first subpixel SPX1 may include a 1-1 line b1-1 corresponding to (or facing) the 1-1 line segment b1 of the first reference subpixel BX1. The first subpixel SPX1 may also include a 1-2 line b1-2, a 1-3 line b1-3, and a 1-4 line b1-4 corresponding to (or facing) the line segments extending in the long axis direction of other reference subpixels. For example, the 1-2 line b1-2 of the first subpixel SPX1 may correspond to (or face) the 2-1 line segment b1' of the second reference subpixel BX2.

[0139] An extension line of the 1-1 line b1-1 may intersect (eg, substantially perpendicularly intersect) extension lines of the 1-2 line b1-2 and the 1-3 line b1-3, and the 1-1 line b1-1 may be arranged substantially parallel to the 1-4 line b1-4.

[0140] The second subpixel SPX2 may include a 2-1 line b2-1 corresponding to (or facing) the 1-2 line segment b2 of the first reference subpixel BX1. The second subpixel SPX2 may also include a 2-2 line b2-2, a 2-3 line b2-3, and a 2-4 line b2-4 corresponding to (or facing) the line segments extending in the short axis direction of the other reference subpixels. For example, the 2-2 line b2-2 of the second subpixel SPX2 may correspond to (or face) the 2-2 line segment b2' of the second reference subpixel BX2.

[0141] An extension line of the 2-1st line b2-1 may intersect (eg, substantially perpendicularly intersect) an extension line of the 2-2nd line b2-2 and an extension line of the 2-3rd line b2-3, and the 2-1st line b2-1 may be arranged substantially parallel to the 2-4th line b2-4.

[0142] The length of the 1-1 line segment b1 may be substantially the same as the length of the 1-1 line b1-1. The length of the 1-1 line segment b1 may be substantially the same as the length of the 1-4 line b1-4.

[0143] The third reference sub-pixel BX3 and the first reference sub-pixel BX1 may have the same specifications, and the third reference sub-pixel BX3 may be arranged in the area A1. The third reference sub-pixel BX3 may be symmetrical with the first reference sub-pixel BX1 based on an imaginary axis (e.g., the second imaginary axis Vx2) that passes through the center of the first sub-pixel SPX1 and extends in the x-axis direction. The symmetry may also be applied to the fourth reference sub-pixel BX4 that is positioned symmetrical with the first reference sub-pixel BX1 about the first sub-pixel SPX1 or an imaginary axis that passes through the center of the first sub-pixel SPX1 and extends between the x-axis direction and the y-axis direction.

[0144] According to the symmetry described above, the length of the 1-1 line segment b1 and the length of the 1-2 line b1-2 may be substantially the same, and the length of the 1-1 line segment b1 and the 1-3 line b1-3 may be substantially the same.

[0145] The equality or similarity of the lengths may be because the 1-1 line b1-1 is defined as being tangent to an imaginary circle having each of the points constituting the 1-1 line segment b1 as an origin and having a distance (e.g., a certain or selectable distance) R as a radius. In an embodiment, the 1-1 line b1-1 may be tangent to all of the imaginary circles having a distance (e.g., a certain or selectable distance) R as a radius based on the origin on the 1-1 line segment b1 with each of the points constituting the 1-1 line segment b1 as an origin. As a result, the 1-1 line b1-1 and the 1-1 line segment b1 may always be spaced apart from each other by a distance (e.g., a certain or selectable distance) R.

[0146] Similarly, the 1-2 line b1-2 may be defined by an imaginary circle drawn based on a line segment of the second reference subpixel BX2 positioned closest to the 1-2 line b1-2 (e.g., the 2-1 line segment b1′). The 1-3 line b1-3 may be defined by an imaginary circle drawn based on a line segment of the third reference subpixel BX3 positioned closest to the 1-3 line b1-3. The 1-4 line b1-4 may be defined by an imaginary circle drawn based on a line segment of the fourth reference subpixel (e.g., the 2-1 line segment b1′). Figure 4 The fourth reference sub-pixel BX4 of the first sub-pixel SPX1 is positioned closest to the imaginary circle drawn by the line segment of the 1-4th line b1-4. The imaginary circle has a radius equal to the distance (e.g., a certain or selectable distance) R, and the line included in the first sub-pixel SPX1 may be evenly spaced apart from all of the adjacent reference sub-pixels BX1, BX2, BX3, and BX4 by the distance (e.g., a certain or selectable distance) R. For example, the line included in the first sub-pixel SPX1 may be spaced apart from all of the adjacent reference sub-pixels BX1, BX2, BX3, and BX4 by an equal interval.

[0147] The length of the 1-2 line segment b2 and the length of the 2-1 line b2-1 may be substantially the same. The length of the 1-2 line segment b2 and the length of the 2-4 line b2-4 may be substantially the same.

[0148] The fifth reference subpixel BX5 and the second reference subpixel BX2 may have the same specifications, and the fifth reference subpixel BX5 may be arranged in the area A1. The fifth reference subpixel BX5 may be symmetrical with the second reference subpixel BX2 based on the second subpixel SPX2. The symmetry may also apply to the sixth reference subpixel BX6 positioned symmetrically with the first reference subpixel BX1 based on the second subpixel SPX2.

[0149] According to the symmetry described above, the length of the 1-2 line segment b2 and the length of the 2-2 line b2-2 may be substantially the same, and the length of the 1-2 line segment b2 and the 2-3 line b2-3 may be substantially the same.

[0150] The equality or similarity of the lengths may be because the 2-1st line b2-1 is defined as being tangent to an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R from the origin of each of the points constituting the 1-2nd line segment b2 (or a radius of a distance (e.g., a certain or selectable distance) R from the origin on the 1-2nd line segment b2). In an embodiment, the 2-1st line b2-1 may be tangent to all of the imaginary circles having an origin at each of the points constituting the 1-2nd line segment b2 and having a radius of a distance (e.g., a certain or selectable distance) R. As a result, the 2-1st line b2-1 and the 1-2nd line segment b2 may always be spaced apart from each other by a distance (e.g., a certain or selectable distance) R.

[0151] Similarly, the 2-2nd line b2-2 may be defined by an imaginary circle drawn based on a line segment (eg, 2-2nd line segment b2′) of the second reference subpixel BX2 positioned closest to the 2-2nd line b2-2. The 2-4th line b2-4 may be defined by an imaginary circle drawn based on a sixth reference subpixel (eg, Figure 4 The 2-3 line b2-3 may be defined by an imaginary circle drawn based on a line segment of the fifth reference subpixel BX5 that is positioned closest to the 2-3 line b2-3. The imaginary circles all have a radius equal to a distance (e.g., a certain or selectable distance) R, and the lines included in the second subpixel SPX2 may be evenly spaced apart from all of the adjacent reference subpixels BX1, BX2, BX5, and BX6 by a distance (e.g., a certain or selectable distance) R. For example, the lines included in the second subpixel SPX2 may be spaced apart from all of the adjacent reference subpixels BX1, BX2, BX5, and BX6 by equal spacing.

[0152] The 1-1 angle a° formed by the intersection of the 1-1 line segment b1 and the 1-1 oblique side segment b12 of the first reference subpixel BX1 may be an obtuse angle. The 1-1 angle a° may be the smaller of the two angles formed by the intersection of the 1-1 line segment b1 and the 1-1 oblique side segment b12 (for example, the sum of the two angles is about 360°).

[0153] The 1-2 angle b° formed by the intersection of the 1-2 line segment b2 and the 1-1 oblique side segment b12 of the first reference subpixel BX1 may be an obtuse angle. The 1-2 angle b° may be the smaller of the two angles formed by the intersection of the 1-2 line segment b2 and the 1-1 oblique side segment b12 (for example, the sum of the two angles is about 360°).

[0154] The 1-3rd angle c° formed by the intersection of the 1-3rd line segment b2 and the 1-2nd oblique side segment b23 of the first reference subpixel BX1 may be an obtuse angle. The 1-3rd angle c° may be the smaller of the two angles formed by the intersection of the 1-2nd line segment b2 and the 1-2nd oblique side segment b23 (for example, the sum of the two angles is about 360°).

[0155] The first reference subpixel BX1 may have other angles (for example, in the case where the first reference subpixel BX1 is an octagon, it may have other angles, such as angles 1-4 to 1-8 and the like), and for the convenience of explanation, the contents of angles 1-4 to 1-8 and the like may be replaced by the contents described above.

[0156] like Figure 5 As shown in FIG. 1 , the angle formed by the intersection of the extension line of the 1-1 line b1-1 and the first imaginary axis Vx1 may be substantially equal to the 1-1 angle a°. This is because the 1-1 oblique side segment b12 and the first imaginary axis Vx1 are arranged substantially parallel to each other.

[0157] The angle formed by the intersection of the extension line of the 2-1st line b2-1 and the first imaginary axis Vx1 may be substantially equal to the 1-2nd angle b°. This is also because the 1-1st oblique side segment b12 and the first imaginary axis Vx1 are arranged substantially parallel to each other.

[0158] The angle formed by the intersection of the extension line of the 2-1st line b2-1 and the second imaginary axis Vx2 may be substantially equal to the 1-3rd angle c°. This is because the 1-2nd hypotenuse segment b23 and the second imaginary axis Vx2 are arranged substantially parallel to each other. The second imaginary axis Vx2, which is an imaginary axis extending in the x-axis direction, may intersect (e.g., substantially perpendicularly intersect) the first imaginary axis Vx1.

[0159] Each of the other angles of the first reference subpixel BX1 may also be equal to a corresponding one of the other angles between the line of other adjacent subpixels SPX1, SPX2, SPX3 or SPX4 and the imaginary axis Vx1 and / or Vx2, which will be omitted for convenience of explanation.

[0160] Figure 6 and Figure 7 It is shown that the arrangement Figure 5 Schematic plan view of a sub-pixel in area A1-1 of FIG.

[0161] For convenience of explanation, the description will focus on the sub-pixels arranged in the area A1 - 1 , and descriptions of other components may be omitted. Figure 6 and Figure 7 are plan views and unless otherwise requested, Figure 6 and Figure 7 The description can be understood as being based on a plan view.

[0162] like Figure 6 and Figure 7 As shown in , the first reference subpixel BX1 may have a plurality of vertices P1 to P8. For example, in the case where the first reference subpixel BX1 is a polygon, the number of vertices may be equal to the number of corners of the polygon in the first reference subpixel BX1. For example, the first reference subpixel BX1 having an octagonal shape in a plan view may include a 1-1 th vertex P1 to a 1-8 th vertex P8.

[0163] For example, the second reference subpixel BX2 having an octagonal shape in a plan view may be symmetrical to the first reference subpixel BX1 based on the first imaginary axis Vx1, and the second reference subpixel BX2 may also include 2-1st to 2-8th vertices P1′ to P8′ symmetrical to the 1-1st to 1-8th vertices P1 to P8, respectively.

[0164] In an embodiment, the first subpixel SPX1 may include a 1-1th angle E1-1, a 1-2th angle E1-2, a 1-3th angle E1-3, and a 1-4th angle E1-4. The 1-1th angle E1-1 and the 1-2th angle E1-2 may be connected to each other through a 1-1th line b1-1, the 1-1th angle E1-1 and the 1-3th angle E1-3 may be connected to each other through a 1-2th line b1-2, the 1-2th angle E1-2 and the 1-4th angle E1-4 may be connected to each other through a 1-3th line b1-3, and the 1-3rd angle E1-3 and the 1-4th angle E1-4 may be connected to each other through a 1-4th line b1-4.

[0165] In an embodiment, the shape of the first subpixel SPX1 may include a 1-1 line b1-1 corresponding to (or facing) the 1-1 line segment b1 and a 1-1 angle E1-1 connected to the 1-1 line b1-1 and protruding toward the second subpixel SPX2 on the first imaginary axis Vx1 in a plan view. For example, a length D1 of the 1-1 line b1-1 may correspond to a length D10 of the 1-1 line segment b1.

[0166] In an embodiment, the 1-1 line b1-1 may be tangent to an imaginary circle with a radius of a distance (e.g., a certain or selectable distance) R based on the origin on the 1-1 line segment b1 (or centered on the origin on the 1-1 line segment b1) within an imaginary circle with a radius of a distance (e.g., a certain or selectable distance) R based on the origin on one side of the reference sub-pixels BX1 and BX2.

[0167] As described above, the first subpixel SPX1 may be spaced apart from the first reference subpixel BX1 by a distance (eg, a certain or selectable distance) R. In a plan view, the 1-1th to 1-4th angles E1-1 to E1-4 may include curves that are substantially bent inward.

[0168] For example, the 1-1st angle E1-1 may include a 1-1a curve C1-1a and a 1-1b curve C1-1b that is substantially symmetrical to the 1-1a curve C1-1a based on the first imaginary axis Vx1. For example, the 1-1st angle E1-1 may be defined by a 1-1a curve C1-1a that is substantially bent inward, a 1-1b curve C1-1b, and a 1-1c curve C1-1c that connects the 1-1a curve C1-1a and the 1-1b curve C1-1b and protrudes toward the second sub-pixel SPX2.

[0169] The 1-1a-th curve C1-1a may have the 1-1th vertex P1 of the first reference subpixel BX1 as an origin, and may extend along the 1-1th imaginary circle VC1-1 having a distance (e.g., a certain or selectable distance) R as a radius. The 1-1a-th curve C1-1a may be a curve curved along the circumference of the 1-1th imaginary circle VC1-1.

[0170] For example, the length of the 1-1a curve C1-1a may have the 1-1 vertex P1 of the first reference subpixel BX1 as the origin and may be substantially equal to the length of the 1-1 arc L1 of the fan shape defined by the 1-1 arc of the circumference of the 1-1 imaginary circle VC1-1 having the distance R as the radius.

[0171] For example, the 1-1a curve C1-1a may be a 1-1 arc L1 in the shape of a fan, which is rotated by a 1-1 arc (angle k1°) from an imaginary baseline extending perpendicular to the 1-1 line segment b1 at the 1-1 vertex P1 in the circumference of the 1-1 imaginary circle VC1-1 having the 1-1 vertex P1 as the origin and a distance (for example, a certain or selectable distance) R as a radius.

[0172] In an embodiment, the 1-1th angle E1-1 may be partially defined by a 1-1a curve C1-1a curved with the curvature of the circumference of an imaginary circle. The imaginary circle may be an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on the 1-1 vertex P1 of the first reference subpixel BX1 (or centered on the 1-1 vertex P1 of the first reference subpixel BX1) among an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on an origin on one side of the reference subpixels BX1 and BX2. The 1-1 vertex P1 may be the vertex closest to the 1-1th angle E1-1 among the vertices constituting the polygonal shape of the first reference subpixel BX1 in a plan view.

[0173] The 1-1b-th curve C1-1b may have the 2-1st vertex P1' of the second reference subpixel BX2 as an origin, and may extend along the 2-1st imaginary circle VC2-1 having a distance (e.g., a certain or selectable distance) R as a radius. The 1-1b-th curve C1-1b may be a curve curved along the circumference of the 2-1st imaginary circle VC2-1.

[0174] For example, the length of the 1-1b curve C1-1b may have the 2-1st vertex P1' of the second reference subpixel BX2 as an origin and may be substantially equal to the length of the 2-1st arc of the fan shape defined by the 2-1st arc of the circumference of the 2-1st imaginary circle VC2-1 having the distance R as a radius.

[0175] For example, the 1-1b curve C1-1b may be a 2-1 arc fanned by a 2-1 arc from an imaginary baseline extending perpendicular to the 2-1 line segment b1' at the 2-1 vertex P1' in the circumference of the 2-1 imaginary circle VC2-1 having the 2-1 vertex P1' as the origin and a distance (e.g., a certain or selectable distance) R as the radius. The 2-1 arc and the 1-1 arc may be substantially the same angle k1°.

[0176] In an embodiment, the 1-1st angle E1-1 may be partially defined by a 1-1b curve C1-1b curved with a curvature of the circumference of an imaginary circle. The imaginary circle may be an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on the 2-1st vertex P1' of the second reference sub-pixel BX2 among an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on an origin on one side of the reference sub-pixels BX1 and BX2. The 2-1st vertex P1' may be a vertex closest to the 1-1st angle E1-1 among the vertices of the polygonal shape constituting the second reference sub-pixel BX2 in a plan view.

[0177] The 1-1c curve C1-1c, which is a curve connecting the 1-1a curve C1-1a and the 1-1b curve C1-1b to each other, may be a convex line protruding from the center of the first sub-pixel SPX1 toward the center of the second sub-pixel SPX2. In another embodiment, the 1-1c curve C1-1c, which is a curve connecting the 1-1a curve C1-1a and the 1-1b curve C1-1b to each other, may be a convex line protruding in the -y axis direction from the center of the first sub-pixel SPX1.

[0178] The 1-1c curve C1-1c may vary due to the distance between the first reference sub-pixel BX1 and the second reference sub-pixel BX2 (e.g., the distance between the closest vertices or similar parameters) and the distance between the first sub-pixel SPX1 and the second sub-pixel SPX2 (e.g., the distance between the center point or reference point of each sub-pixel or similar parameters).

[0179] Similarly, the first subpixel SPX1 may further include a 1-2 angle E1-2 including a 1-2a curve C1-2a, a 1-2b curve C1-2b, and a 1-2c curve C1-2c connecting the 1-2a curve C1-2a and the 1-2b curve C1-2b to each other. Features of each of the curves C1-2a, C1-2b, and C1-2c constituting the 1-2 angle E1-2 and features of each of the curves C1-1a, C1-1b, and C1-1c constituting the 1-1 angle E1-1 symmetrical to the 1-2 angle E1-2 based on the 1-1 line b1-1 may be substantially the same or similar. However, the present disclosure is not limited thereto, and the vertex of the imaginary circle used to define the 1-2a curve C1-2a may be the 1-8 vertex P8, and the vertex of the imaginary circle used to define the 1-2b curve C1-2b may be Figure 5 The vertex of the third reference sub-pixel BX3 located closest to the 1-2b-th curve C1-2b among the vertices of the third reference sub-pixel BX3. In addition, a criterion for defining the 1-2c-th curve C1-2c may be a convex line protruding from the center of the first sub-pixel SPX1 in the x-axis direction.

[0180] Some of the curves constituting the angles E1-1 to E1-4 included in the first subpixel SPX1 may be defined by an imaginary circle based on the adjacent reference subpixels BX1 and BX2, and other of the curves constituting the edges included in the first subpixel SPX1 may be defined by a line protruding in a direction (e.g., a specific direction) from the center of the first subpixel SPX1. The angles E1-1 to E1-4 included in the first subpixel SPX1 may be substantially symmetrical with respect to the center of the first subpixel SPX1, and the overall features may be self-evident to those skilled in the art only through the above description and the accompanying drawings.

[0181] As described above, the second subpixel SPX2 may be spaced apart from the first reference subpixel BX1 by a distance (eg, a certain or selectable distance) R. In a plan view, the 2-1st to 2-4th angles E2-1 to E2-4 may include curves that are substantially bent inward.

[0182] In an embodiment, the second subpixel SPX2 may include a 2-1st corner E2-1, a 2-2nd corner E2-2, a 2-3rd corner E2-3, and a 2-4th corner E2-4. The 2-1st corner E2-1 and the 2-2nd corner E2-2 may be connected to each other through a 2-1st line b2-1, the 2-1st corner E2-1 and the 2-3rd corner E2-3 may be connected to each other through a 2-2nd line b2-2, the 2-2nd corner E2-2 and the 2-4th corner E2-4 may be connected to each other through a 2-3rd line b2-3, and the 2-3rd corner E2-3 and the 2-4th corner E2-4 may be connected to each other through a 2-4th line b2-4.

[0183] In an embodiment, the shape of the second subpixel SPX2 may include a 2-1st line b2-1 corresponding to (or facing) the 1-2nd line segment b2 and a 2-1st angle E2-1 connected to the 2-1st line b2-1 and protruding toward the first subpixel SPX1 on the first imaginary axis Vx1 in a plan view. For example, the length D2 of the 2-1st line b2-1 may correspond to the length D20 of the 1-2nd line segment b2.

[0184] In an embodiment, the 2-1st line b2-1 may be tangent to all of an imaginary circle having an origin at each of the points constituting the 1-2nd line segment b2 and having a radius of a distance (e.g., a certain or selectable distance) R. The imaginary circle may be a different portion of an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on an origin on one side of the reference subpixels BX1 and BX2.

[0185] For example, the 2-1st angle E2-1 may include a 2-1a curve C2-1a and a 2-1b curve C2-1b that is substantially symmetrical to the 2-1a curve C2-1a based on the first imaginary axis Vx1. For example, the 2-1st angle E2-1 may be defined by a 2-1a curve C2-1a that is substantially bent inward, a 2-1b curve C2-1b, and a 2-1c curve C2-1c that connects the 2-1a curve C2-1a and the 2-1b curve C2-1b and protrudes toward the first sub-pixel SPX1.

[0186] The 2-1a curve C2-1a may have the 1-2 vertex P2 of the first reference subpixel BX1 as an origin, and may extend along the 1-2 imaginary circle VC1-2 having a distance (e.g., a certain or selectable distance) R as a radius. The 2-1a curve C2-1a may have the 1-2 vertex P2 of the first reference subpixel BX1 as an origin, and may be a curve curved along the circumference of the 1-2 imaginary circle VC1-2 having a distance (e.g., a certain or selectable distance) R as a radius.

[0187] In an embodiment, the 2-1st angle E2-1 may be partially defined by a 2-1a curve C2-1a curved with a curvature of the circumference of an imaginary circle. The imaginary circle may be an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on the 1-2 vertex P2 of the first reference subpixel BX1 among an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on an origin on one side of the reference subpixels BX1 and BX2. The 1-2 vertex P2 may be a vertex closest to the 2-1st angle E2-1 among the vertices of the polygonal shape constituting the first reference subpixel BX1 in a plan view.

[0188] For example, the length of the 2-1a curve C2-1a may have the 1-2 vertex P2 of the first reference subpixel BX1 as the origin and may be substantially equal to the length of the 1-2 arc L2 of the fan shape defined by the 1-2 arc of the circumference of the 1-2 imaginary circle VC1-2 having the distance R as the radius.

[0189] For example, the 2-1a curve C2-1a may be a 1-2 arc L2 in the shape of a fan rotated by the 1-2 arc from an imaginary baseline extending perpendicular to the 1-2 line segment b2 at the 1-2 vertex P2 in the circumference of the 1-2 imaginary circle VC1-2 having the 1-2 vertex P2 as the origin and the distance (for example, a certain or selectable distance) R as the radius.

[0190] The 2-1b-th curve C2-1b may have the 2-2nd vertex P2' of the second reference sub-pixel BX2 as an origin, and may extend along the 2-2nd imaginary circle VC2-2 having a distance (e.g., a certain or selectable distance) R as a radius. The 2-1b-th curve C2-1b may have the 2-2nd vertex P2' of the second reference sub-pixel BX2 as an origin, and may be a curve curved along the circumference of the 2-2nd imaginary circle VC2-2 having a distance (e.g., a certain or selectable distance) R as a radius.

[0191] For example, the length of the 2-1b curve C2-1b may have the 2-2nd vertex P2' of the second reference subpixel BX2 as an origin and may be substantially equal to the length of the 2-2nd arc of the fan shape defined by the 2-2nd arc of the circumference of the 2-2nd imaginary circle VC2-2 having the distance R as a radius.

[0192] For example, the 2-1b curve C2-1b may be a 2-2nd arc fanned by a 2-2nd arc from an imaginary baseline extending perpendicular to the 2-2nd line segment b2' at the 2-2nd vertex P2' in the circumference of the 2-2nd imaginary circle VC2-2 having the 2-2nd vertex P2' as the origin and a distance (e.g., a certain or selectable distance) R as the radius. The 2-2nd arc may be an angle k2° substantially the same as the 1-2nd arc.

[0193] In an embodiment, the 2-1st angle E2-1 may be partially defined by a 2-1b curve C2-1b curved with a curvature of the circumference of an imaginary circle. The imaginary circle may refer to an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R from a 2-2nd vertex P2' based on the second reference sub-pixel BX2 among an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R from an origin on one side of the reference sub-pixels BX1 and BX2. The 2-2nd vertex P2' may be a vertex closest to the 2-1st angle E2-1 among the vertices of the polygonal shape constituting the second reference sub-pixel BX2 in a plan view.

[0194] The 2-1c curve C2-1c, which is a curve connecting the 2-1a curve C2-1a and the 2-1b curve C2-1b to each other, may be a convex line protruding from the center of the second sub-pixel SPX2 toward the center of the first sub-pixel SPX1. In another embodiment, the 2-1c curve C2-1c, which is a curve connecting the 2-1a curve C2-1a and the 2-1b curve C2-1b to each other, may be a convex line protruding in the +y-axis direction from the center of the second sub-pixel SPX2.

[0195] The 2-1c curve C2-1c may vary due to the distance between the first reference sub-pixel BX1 and the second reference sub-pixel BX2 (e.g., the distance between the closest vertices or similar parameters) and the distance between the first sub-pixel SPX1 and the second sub-pixel SPX2 (e.g., the distance between the center point or reference point of each sub-pixel or similar parameters).

[0196] Similarly, the second subpixel SPX2 may further include a 2-2 angle E2-2 including a 2-2a curve C2-2a, a 2-2b curve C2-2b, and a 2-2c curve C2-2c connecting the 2-2a curve C2-2a and the 2-2b curve C2-2b to each other. Features of each of the curves C2-2a, C2-2b, and C2-2c constituting the 2-2 angle E2-2 and features of each of the curves C2-1a, C2-1b, and C2-1c constituting the 2-1 angle E2-1 symmetrical to the 2-2 angle E2-2 based on the 2-1 line b2-1 may be substantially the same or similar. However, the present disclosure is not limited thereto, and the vertex of the imaginary circle used to define the 2-2a curve C2-2a may be the 1-3 vertex P3, and the vertex of the imaginary circle used to define the 2-2b curve C2-2b may be the vertex located closest to the 2-2b curve C2-2b among the vertices of other reference sub-pixels (not shown) symmetrical with the second reference sub-pixel BX2 based on the second sub-pixel SPX2. In addition, the standard used to define the 2-2c curve C2-2c may be a convex line protruding from the center of the second sub-pixel SPX2 in the +x-axis direction.

[0197] Some of the curves constituting the angles E2-1 to E2-4 included in the second subpixel SPX2 may be defined by an imaginary circle based on the adjacent reference subpixels BX1 and BX2, and others of the curves including edges included in the second subpixel SPX2 may be defined by a line protruding in a direction (e.g., a specific direction) from the center of the second subpixel SPX2. The angles E2-1 to E2-4 included in the second subpixel SPX2 may be substantially symmetrical with respect to the center of the second subpixel SPX2, and the overall features may be self-evident to those skilled in the art only through the above description and the accompanying drawings.

[0198] In addition, the standard for defining the angles E1-1 to E1-4 included in the first subpixel SPX1 may define edges included in other subpixels that are symmetrical to the first subpixel SPX1, or the other subpixels and the first subpixel SPX1 have approximately the same shape in a plan view, and such application is self-evident to those skilled in the art only through the above description and drawings of the present specification.

[0199] In addition, the standard for defining the angles E2-1 to E2-4 included in the second subpixel SPX2 may define the angles included in other subpixels that are symmetrical to the second subpixel SPX2, or the other subpixels and the second subpixel SPX2 may have approximately the same shape in a plan view, and such application is self-evident to those skilled in the art only through the above description and drawings of the present specification.

[0200] like Figure 6 and Figure 7 As shown in , the overall shape of the 1-1a curve C1-1a of the 1-1 angle E1-1, the 1-2a curve C1-2a of the 1-2 angle E1-2, and the 1-1 line b1-1 connecting the 1-1a curve C1-1a and the 1-2a curve C1-2a to each other may correspond to a partial shape of the first reference subpixel BX1. The overall shape of the 1-1a curve C1-1a of the 1-1 corner E1-1, the 1-2a curve C1-2a of the 1-2 corner E1-2, and the 1-1 line b1-1 connecting the 1-1a curve C1-1a and the 1-2a curve C1-2a to each other may correspond to the shapes of the 1-1 line segment b1 of the first reference subpixel BX1, a portion of the circumference of the 1-1 imaginary circle VC1-1 with a radius of a distance (e.g., a certain or selectable distance) R based on the 1-1 vertex P1, and a portion of the circumference of the 1-8 imaginary circle VC1-8 with a radius of a distance (e.g., a certain or selectable distance) R based on the 1-8 vertex P8.

[0201] In summary, the shape of the 1-1 line b1-1 connecting a portion of the 1-1 angle E1-1 (e.g., the 1-1a curve C1-1a) and a portion of the 1-2 angle E1-2 (e.g., the 1-2a curve C1-2a) may be defined by the 1-1 line segment b1 of the first reference subpixel BX1, a portion of the circumference of the 1-1 imaginary circle VC1-1 having a radius of a distance (e.g., a certain or selectable distance) R based on the 1-1 vertex P1, and a portion of the circumference of the 1-8 imaginary circle VC1-8 having a radius of a distance (e.g., a certain or selectable distance) R based on the 1-8 vertex P8. The 1-1 vertex P1 and the 1-8 vertex P8 may correspond to two endpoints of the 1-1 line b1-1.

[0202] The display device according to the embodiment may include a first reference sub-pixel BX1, a second reference sub-pixel BX2, a first sub-pixel SPX1, and a second sub-pixel SPX2. Some parts of the 1-1st corner E1-1 of the first sub-pixel SPX1 may be a curve defined by an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on the vertices of the first reference sub-pixel BX1 and an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on the vertices of the second reference sub-pixel BX2. Other parts of the 1-1st corner E1-1 of the first sub-pixel SPX1 may be a curve that connects the curves defined by the imaginary circles described above and bulges (or protrudes) in the outward direction of the first sub-pixel SPX1.

[0203] A portion of one side of the first subpixel SPX1 arranged around the first reference subpixel BX1 may be spaced apart from the first reference subpixel BX1 at an equal interval. The first subpixel SPX1 may be spaced apart from the first reference subpixel BX1 at an equal interval. The first subpixel SPX1 may be uniformly spaced apart from the first reference subpixel BX1 at a distance (e.g., a certain or selectable distance) R.

[0204] The "distance R" in this specification is a certain, predetermined or selectable distance, which may be changed according to design or resolution or similar features. As used herein, the "distance R" is a preset distance, which may mean the same distance.

[0205] The sub-pixel in this specification may have a shape defined by a combination of straight lines and curves in a plan view. The straight lines and curves of the sub-pixel may be defined by an imaginary circle having a radius of a distance (e.g., a certain or selectable distance) R based on points constituting the sides of adjacent reference sub-pixels.

[0206] As in the present disclosure, with the reference sub-pixel arranged centrally (see e.g. Figure 4 Sub-pixels (see, for example, the first sub-pixel SPX1 to the fourth sub-pixel SPX4) spaced at equal intervals from the first reference sub-pixel BX1) may have a beneficial effect on ensuring the aperture ratio. In the case where the sub-pixels and the reference sub-pixels are not spaced at equal intervals from each other, uniform light emission through the light emitting element may be adversely affected.

[0207] Furthermore, the curved lines constituting the angles included in the sub-pixels are spaced apart from the vertices of the reference sub-pixels at equal intervals, and the present disclosure may have an advantage of securing an aperture ratio as described above.

[0208] Pixel defining layer (see e.g. Figure 3The pixel defining layer 106 may be arranged between the sub-pixel and the reference sub-pixel. The pixel defining layer may have a pixel defining layer gap (hereinafter, a PDL gap), the corners of the sub-pixels may extend beyond the PDL gap required to maintain equal spacing, and the light emitting area of ​​the sub-pixels may be maximized. For example, the present disclosure may have the effect of utilizing the space between sub-pixels as effectively as possible according to the design of the corners included in each sub-pixel. In addition, as the recently developed fine processes expand the diversity of pixel designs, it may be important to have a pixel design such as the present disclosure that utilizes the fine processes and makes the most effective use of the space between sub-pixels.

[0209] For this reason, maintaining equal spacing between sub-pixels can be very important. Maintaining equal spacing between sub-pixels is possible when the sub-pixels are set as references in the pixel design (e.g., first reference sub-pixels) and an imaginary circle with the same radius is used that passes through the sides of the reference sub-pixels.
