[0049] Figure 1 This is a plan view of an exemplary embodiment of the display device 20. Figure 2 yes Figure 1 A cross-sectional view of the sub-pixel portion of the display device 20. Figure 3 By magnification Figure 1 Part X1 is used to illustrate a plan view of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 of the display device 20.

[0050] refer to Figures 1 to 3 In the display device 20, the display area DA and the non-display area NDA outside the display area DA can be defined on the substrate 21. A light emitter portion can be arranged in the display area DA, and power lines (not shown) can be arranged in the non-display area NDA. Additionally, a pad portion C can be arranged in the non-display area NDA.

[0051] In this case, the display area DA can have various shapes. For example, in an exemplary embodiment, the display area DA can have a rectangular, square, or circular shape. Additionally, the display area DA can have an irregular shape. However, for ease of description, the case where the display area DA has a rectangular shape will be described in detail below.

[0052] The display device 20 may include a display substrate D and a thin-film encapsulation layer E. The display substrate D may include a substrate 21, a thin-film transistor (TFT), a passivation layer 27, and a pixel electrode 28-1. In another exemplary embodiment, the display substrate D may include some of the substrate 21, the thin-film transistor (TFT), the passivation layer 27, the pixel electrode 28-1, and an intermediate layer 28-2.

[0053] In an exemplary embodiment, substrate 21 may comprise a plastic material or a metallic material such as stainless steel (“SUS”) or titanium (Ti). Alternatively, substrate 21 may comprise polyimide. Hereinafter, for ease of description, the case where substrate 21 comprises polyimide is described in detail.

[0054] A thin-film transistor (TFT) can be disposed on substrate 21, and a passivation layer 27 is disposed to cover the TFT. An organic light-emitting diode (“OLED”) 28 can be disposed on passivation layer 27.

[0055] A buffer layer 22, comprising organic and / or inorganic compounds, may be further disposed on the upper surface of the substrate 21. For example, in an exemplary embodiment, the buffer layer 22 may comprise SiO2. x (x≥1) or SiN x (x≥1).

[0056] An active layer 23 arranged in a predetermined pattern is provided on a buffer layer 22. The active layer 23 is then buried in a gate insulating layer 24. The active layer 23 includes a source region 23-1, a drain region 23-3, and a channel region 23-2 between the source region 23-1 and the drain region 23-3.

[0057] The active layer 23 can be provided to comprise various materials. For example, in an exemplary embodiment, the active layer 23 may comprise an inorganic semiconductor material such as amorphous silicon or crystalline silicon. In another exemplary embodiment, the active layer 23 may comprise an oxide semiconductor. In yet another exemplary embodiment, the active layer 23 may comprise an organic semiconductor material. However, for ease of description, the case where the active layer 23 comprises amorphous silicon will be described in detail below.

[0058] The active layer 23 can be provided by forming an amorphous silicon layer on the buffer layer 22, crystallizing the amorphous silicon layer to form a polycrystalline silicon layer, and then patterning the polycrystalline silicon layer. Depending on the type of thin-film transistor TFT, such as a driving thin-film transistor (not shown), a switching thin-film transistor (not shown), etc., the source region 23-1 and the drain region 23-3 in the active layer 23 are doped with impurities.

[0059] On the upper surface of the gate insulating layer 24, a gate electrode 25 corresponding to the active layer 23 and an interlayer insulating layer 26 in which the gate electrode 25 is buried are arranged.

[0060] Additionally, the contact hole H1 can be confined within the interlayer insulating layer 26 and the gate insulating layer 24. The source electrode 27-1 and the drain electrode 27-2 can be arranged on the interlayer insulating layer 26 to contact the source region 23-1 and the drain region 23-3, respectively.

[0061] Passivation layer 27 can be disposed on the upper portion of the thin-film transistor TFT, and pixel electrode 28-1 of OLED 28 can be disposed on passivation layer 27. Pixel electrode 28-1 contacts drain electrode 27-2 of thin-film transistor TFT through aperture H2 in passivation layer 27. Passivation layer 27 can comprise a single layer, two or more layers comprising inorganic and / or organic materials. Passivation layer 27 can include a planarization layer to have a flat upper surface regardless of curvature of the layer beneath the planarization layer. In an alternative exemplary embodiment, passivation layer 27 can be provided to be bent according to the curvature of the layer beneath it. Additionally, passivation layer 27 can include a transparent insulator to achieve a resonant effect.

[0062] Pixel defining layer 29 is arranged to cover pixel electrode 28-1 and passivation layer 27, and includes organic and / or inorganic materials, with an opening OP for exposing pixel electrode 28-1 defined in pixel defining layer 29. In some exemplary embodiments, pixel defining layer 29 may include a black material or a material having an optical density (“OD”) of 1. Pixel defining layer 29 including a black material or a material having an OD of 1 can reduce external light reflection from display device 20.

[0063] Additionally, the intermediate layer 28-2 and the counter electrode 28-3 are disposed at least on the pixel electrode 28-1. In another exemplary embodiment, the counter electrode 28-3 may be disposed on the entire surface of the display area DA. In this case, the counter electrode 28-3 may be disposed on the intermediate layer 28-2 and the pixel defining layer 29. Hereinafter, for ease of description, the case where the counter electrode 28-3 is disposed on the intermediate layer 28-2 and the pixel defining layer 29 will be described in detail.

[0064] Pixel electrode 28-1 serves as the anode electrode. Counter electrode 28-3 serves as the cathode electrode. However, the polarities of pixel electrode 28-1 and counter electrode 28-3 are not limited thereto, and may be reversed in another exemplary embodiment.

[0065] The pixel electrode 28-1 and the counter electrode 28-3 are insulated from each other through the intermediate layer 28-2, and voltages of different polarities are applied to the intermediate layer 28-2, causing the organic emitting layer to emit light.

[0066] Intermediate layer 28-2 may include an organic emission layer. As another optional example, intermediate layer 28-2 may include an organic emission layer, and 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 invention is not limited thereto. Intermediate layer 28-2 may include an organic emission layer, and further include various functional layers (not shown).

[0067] Multiple intermediate layers 28-2 can be provided, and the multiple intermediate layers 28-2 can form a display area DA. In this case, the multiple intermediate layers 28-2 can be arranged in the display area DA in a way that is spaced apart from each other.

[0068] A unit pixel may include multiple sub-pixels. Multiple sub-pixels may emit light of various colors. In an exemplary embodiment, a sub-pixel may be defined as a region therein that emits light of one color. In another exemplary embodiment, a sub-pixel may be defined as the portion of pixel electrode 28-1 exposed to the outside through an opening OP in pixel defining layer 29. In this case, the size of the sub-pixel can be adjusted by adjusting the size of the portion of pixel electrode 28-1 exposed to the outside, thereby adjusting the size of the opening OP in pixel defining layer 29. However, for ease of description, the case where the sub-pixel is a region therein that emits light of one color will be described in detail below.

[0069] For example, the plurality of sub-pixels described above may each include sub-pixels emitting red, green, and blue light. For example, in another exemplary embodiment, the plurality of sub-pixels may include sub-pixels emitting red, green, blue, and white light. For example, in another exemplary embodiment, the plurality of sub-pixels may include sub-pixels emitting red, yellow, and blue light. In this case, the plurality of sub-pixels is not limited to these. All cases in which sub-pixels emitting different colors of light can be included. However, for ease of description, the case where the plurality of sub-pixels includes sub-pixels emitting blue, red, and green light is described in detail below.

[0070] Multiple sub-pixels F may include a first sub-pixel F1, a second sub-pixel F2, and a third sub-pixel F3. In this case, one of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 may have a square 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 rectangular shape. In the following description, for ease of description, the case where the first sub-pixel F1 has a square shape and the second sub-pixel F2 and the third sub-pixel F3 have rectangular shapes is described in detail.

[0071] One of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 described above emits blue light. Another of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 emits green light. Yet another of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 can emit red light. In this case, depending on the respective shapes of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3, one of the blue, green, and red light can have a square shape, and the other of the blue, green, and red light can have a rectangular shape. In the following text, for ease of description, the case where the first sub-pixel F1 emits blue light, the second sub-pixel F2 emits green light, and the third sub-pixel F3 emits red light is described in detail.

[0072] The sizes of the first sub-pixel F1, the second sub-pixel F2, and the third sub-pixel F3 can be configured in various ways. In this case, since the aperture ratio of each sub-pixel F can be adjusted, a display device 20 with various forms and performing various operations can be realized.

[0073] A plurality of first sub-pixels F1, a plurality of second sub-pixels F2, and a plurality of third sub-pixels F3 may be provided separately. The plurality of first sub-pixels F1 may be arranged to be spaced apart from each other in at least one of a first direction and a second direction. In an exemplary embodiment, some of the plurality of first sub-pixels F1 may be in the first direction (e.g., ... Figure 3 The pixels are arranged spaced apart from each other in one of the X-axis and Y-axis directions, and other pixels in the plurality of first sub-pixels F1 can be arranged in a second direction (e.g., Figure 3 The first sub-pixels F1 are arranged spaced apart from each other in the X-axis and Y-axis directions, respectively. In this case, the centers of the first sub-pixels F1 arranged in the first direction can be arranged into a line, and this line can be arranged in a direction parallel to the first direction. Additionally, the centers of the other first sub-pixels F1 arranged in the second direction can be arranged into a line, and this line can be arranged in a direction parallel to the second direction.

[0074] Each first sub-pixel F1 in the first sub-pixel F1 can have its first side S1 defined at a predetermined angle with its second side S2, which is the other side of each first sub-pixel F1. Specifically, the first side S1 and the second side S2 of each first sub-pixel F1 can define a right angle. In this case, the first side S1 and the second side S2 can each be arranged to be inclined in different directions relative to at least one of the first direction and the second direction. Therefore, each first sub-pixel F1 in the first sub-pixel F1 can be arranged in a rhombus shape with respect to one of the first direction and the second direction. In addition, the angle defined by the two sides including the first side S1 and the second side S2 adjacent to each vertex of the first sub-pixel F1 can be approximately 90 degrees.

[0075] In this configuration, the second sub-pixel F2 and the third sub-pixel F3 can be arranged facing the first sub-pixel F1 on either the first side S1 or the second side S2. In this configuration, the second sub-pixel F2 and the third sub-pixel F3 can be arranged tilted toward one of the first and second directions. Specifically, the second sub-pixel F2 and the third sub-pixel F3 can be tilted to define an angle of approximately 45 degrees relative to one of the first and second directions. For example, in an exemplary embodiment, at least one of the short and long sides of at least one of the second sub-pixel F2 and the third sub-pixel F3 can define an angle of approximately 45 degrees relative to the line connecting the centers of the plurality of first sub-pixels F1 arranged in the first direction.

[0076] The second sub-pixel F2 and the third sub-pixel F3 can be rectangular. In this case, the size of at least one of the second sub-pixel F2 and the third sub-pixel F3 can be smaller than the size of the first sub-pixel F1. Furthermore, at least one of the second sub-pixel F2 and the third sub-pixel F3 facing the first sub-pixel F1 can be arranged to overlap with the side of the first sub-pixel F1 facing the second sub-pixel F2 and the third sub-pixel F3 (e.g., the first side S1 or the second side S2) or the extension of that side of the first sub-pixel F1. That is, at least a portion of the second sub-pixel F2 and at least a portion of the third sub-pixel F3 that are adjacent to each other can be arranged within the length of one of the first side S1 and the second side S2. The short or long side of at least one of the second sub-pixel F2 and the third sub-pixel F3 facing the first sub-pixel F1 can be arranged parallel to the first side S1 or the second side S2.

[0077] For example, in an exemplary embodiment, the extensions of the shorter sides of different second sub-pixels F2 facing the first edge S1 and the second edge S2 respectively can intersect each other, or the extensions of the longer sides of different second sub-pixels F2 facing the first edge S1 and the second edge S2 respectively can intersect each other. In another exemplary embodiment, the extensions of the shorter sides of the corresponding third sub-pixels F3 facing the first edge S1 and the second edge S2 respectively can intersect each other, or the extensions of the longer sides of the corresponding third sub-pixels F3 facing the first edge S1 and the second edge S2 respectively can intersect each other. In another exemplary embodiment, the extension of the shorter side of the second sub-pixel F2 facing the first edge S1 can intersect with the extension of the shorter side of the third sub-pixel F3 facing the second edge S2. In an alternative exemplary embodiment, the extension of the longer side of the second sub-pixel F2 facing the first edge S1 can intersect with the extension of the longer side of the third sub-pixel F3 facing the second edge S2. In another exemplary embodiment, the extension of the longer side of the second sub-pixel F2 facing the first side S1 may intersect the extension of the shorter side of the third sub-pixel F3 facing the second side S2. In an alternative exemplary embodiment, the extension of the shorter side of the second sub-pixel F2 facing the first side S1 may intersect the extension of the longer side of the third sub-pixel F3 facing the second side S2.

[0078] The plurality of second sub-pixels F2 described above can be arranged to be spaced apart from each other in at least one of the first and second directions. In an exemplary embodiment, the centers of some of the plurality of second sub-pixels F2 arranged in the first or second direction can be arranged on a line. In another exemplary embodiment, the centers of some of the plurality of second sub-pixels F2 arranged in one of the first and second directions can be arranged on a line. Additionally, the centers of other second sub-pixels F2 arranged in the other of the first and second directions can be arranged in a serpentine or zigzag pattern in the other of the first and second directions. Hereinafter, for ease of description, the case where the centers of some of the plurality of second sub-pixels F2 arranged in the first direction are arranged on a line, and the centers of other second sub-pixels F2 arranged in the second direction are arranged in a serpentine pattern, will be described in detail.

[0079] Similar to the second sub-pixel F2, multiple third sub-pixels F3 can also be arranged to be spaced apart from each other in at least one of the first and second directions. In this case, the multiple third sub-pixels F3 can be arranged similarly to the multiple second sub-pixels F2. For ease of description, the following situation will be described in detail: among the multiple third sub-pixels F3, the centers of some of the third sub-pixels F3 arranged in the first direction are arranged on a line, and among the multiple third sub-pixels F3, the centers of the other third sub-pixels F3 arranged in the second direction are arranged in a serpentine pattern.

[0080] In this case, one of the first edges S1 of the second sub-pixel F2 and the third sub-pixel F3 facing the first sub-pixel F1 can be arranged symmetrically with respect to one of the second edges S2 of the second sub-pixel F2 and the third sub-pixel F3 facing the first sub-pixel F1 about a line connecting the centers of the first sub-pixels F1 arranged in the first direction (or any line passing through the centers of two adjacent first sub-pixels F1 and parallel to the first direction). In an exemplary embodiment, the second sub-pixel F2 facing the first edge S1 can be symmetrically with respect to the third sub-pixel F3 facing the second edge S2 about the line described above. Alternatively, for example, the third sub-pixel F3 facing the first edge S1 can be symmetrically with respect to the second sub-pixel F2 facing the second edge S2 about the line described above. In this case, the distance between the centers of adjacent second sub-pixels F2 can be the same as the distance between the centers of adjacent third sub-pixels F3. In another exemplary embodiment, the respective second sub-pixels F2 and third sub-pixels F3 facing the first edge S1 can be symmetrically with respect to the respective second sub-pixels F2 and third sub-pixels F3 facing the second edge S2 about the line described above. In this case, the distance between the centers of one pair of sub-pixels in a pair of second sub-pixels F2 and a pair of third sub-pixels F3 can be smaller than the distance between the centers of another pair of sub-pixels in the pair of second sub-pixels F2 and the pair of third sub-pixels F3, wherein the pair of second sub-pixels F2 are arranged symmetrically to each other, and the pair of third sub-pixels F3 are arranged symmetrically to each other. In this case, a pair of adjacent second sub-pixels F2 can be arranged between a pair of adjacent third sub-pixels F3. For example, in an alternative exemplary embodiment, a pair of adjacent third sub-pixels F3 can be arranged between a pair of adjacent second sub-pixels F2. However, for ease of description, the case where the second sub-pixels F2 are arranged symmetrically with respect to the third sub-pixels F3 about the line connecting the centers of the first sub-pixels F1 arranged in the first direction is described in detail.

[0081] In the arrangement described above, the first distance d1, which is the shortest distance from the boundary of the first sub-pixel F1 to the second sub-pixel F2, can be the same as the second distance d2, which is the shortest distance from the boundary of the first sub-pixel F1 to the third sub-pixel F3. In this case, the shortest distance can be measured from the first side S1 or the second side S2 to the edge of the second sub-pixel F2 or the edge of the third sub-pixel F3 in a direction perpendicular to one of the first side S1 and the second side S2. In an alternative exemplary embodiment, the shortest distance can be measured from the first side S1 or the second side S2 to the edge of the second sub-pixel F2 or the edge of the third sub-pixel F3 in a direction perpendicular to the extension line of one of the first side S1 and the second side S2. However, for ease of description, the case where the shortest distance is the distance measured from the second sub-pixel F2 or the third sub-pixel F3 facing the first side S1 to the first side S1 or the extension line of the first side S1 is described in detail. In another exemplary embodiment besides the cases described above, the distance from the center of the first sub-pixel F1 to the center of the second sub-pixel F2, or the distance from the center of the first sub-pixel F1 to the center of the third sub-pixel F3, can be measured as the shortest distance. In another exemplary embodiment, the distance from the first side S1 of the first sub-pixel F1 or its extension to the center of the second sub-pixel F2 or the center of the third sub-pixel F3 can be measured as the shortest distance.

[0095] refer to Figure 4A and Figure 4B The first sub-pixel F1 may include a first neighboring sub-pixel OF1 and a first inner sub-pixel IF1. In the planar view, the first neighboring sub-pixel OF1 may have a shape different from that of the first inner sub-pixel IF1.

[0096] In an exemplary embodiment, the first neighboring sub-pixel OF1 and the first inner sub-pixel IF1 can be arranged in the display area DA. The first neighboring sub-pixel OF1 can be arranged in the display area DA to be adjacent to the non-display area NDA. In another exemplary embodiment, the first neighboring sub-pixel OF1 can be arranged in the display area DA to be adjacent to the boundary between the non-display area NDA and the display area DA. In yet another exemplary embodiment, the first neighboring sub-pixel OF1 can be arranged in the display area DA to be adjacent to the boundary of the display area DA. Hereinafter, for ease of description, the case where the first neighboring sub-pixel OF1 is arranged in the display area DA to be adjacent to the non-display area NDA will be described in detail.

[0097] The first neighboring sub-pixel OF1 can have a polygonal shape. In an exemplary embodiment, the first neighboring sub-pixel OF1 can have a pentagonal shape. In another exemplary embodiment, one of the vertices ST of the first neighboring sub-pixel OF1 can be chamfered to form a pentagon. In another exemplary embodiment, the first neighboring sub-pixel OF1 can have a hexagonal shape. However, as described above, the shape of the first neighboring sub-pixel OF1 is not limited to pentagonal or hexagonal.

[0098] The first neighboring sub-pixel OF1 may include the first upper sub-pixel OF1-1, the first right sub-pixel OF1-2, and the first intersecting sub-pixel OF1-3.

[0099] The first upper sub-pixel OF1-1 may include an edge parallel to the boundary of the display area DA. In an exemplary embodiment, the first upper sub-pixel OF1-1 may include an edge S3 parallel to a second direction. In another exemplary embodiment, the first upper sub-pixel OF1-1 may include an edge S3 parallel to the upper boundary U1 of the display area DA. Hereinafter, for ease of description, the case where the first upper sub-pixel OF1-1 includes an edge S3 parallel to the upper boundary U1 of the display area DA will be described in detail.

[0100] The chamfered vertex among the vertices of the first upper sub-pixel OF1-1 can be the portion overlapping with the non-display area NDA. For example, in an exemplary embodiment, when the first upper sub-pixel OF1-1 is arranged adjacent to the upper boundary U1 of the display area DA, the chamfered first vertex ST1 among the vertices of the first upper sub-pixel OF1-1 can be the portion overlapping with the non-display area NDA.

[0101] Multiple first upper sub-pixels OF1-1 can be arranged to be adjacent to and spaced apart from the non-display area NDA. For example, in an exemplary embodiment, the first upper sub-pixels OF1-1 can be arranged to be parallel to and spaced apart from the upper boundary U1 of the display area DA. In another exemplary embodiment, the first upper sub-pixels OF1-1 can be arranged to be adjacent to the non-display area NDA, parallel to the second direction, and spaced apart from each other.

[0102] Similar to the first upper sub-pixel OF1-1, the first right sub-pixel OF1-2 may include an edge parallel to the boundary of the display area DA. Specifically, the first right sub-pixel OF1-2 may include an edge S4 parallel to the right boundary U2 of the display area DA. A chamfered vertex among the vertices of the first right sub-pixel OF1-2 may be a portion overlapping with the non-display area NDA. A second chamfered vertex ST2 among the vertices of the first right sub-pixel OF1-2 may be a portion overlapping with the non-display area NDA. Multiple first right sub-pixels OF1-2 may be arranged to be adjacent to and spaced apart from each other in relation to the non-display area NDA. Specifically, the first right sub-pixels OF1-2 may be arranged to be adjacent to the non-display area NDA, parallel to the right boundary U2 of the display area DA, and spaced apart from each other.

[0103] In an exemplary embodiment, the display device 20 may include first intersecting sub-pixels OF1-3. The first intersecting sub-pixels OF1-3 may include at least two edges parallel to the boundary of the display area DA. For example, in an exemplary embodiment, the first intersecting sub-pixels OF1-3 may include an edge parallel to a second direction and an edge parallel to a first direction. In another exemplary embodiment, the first intersecting sub-pixels OF1-3 may include an edge S3 parallel to the upper boundary U1 of the display area DA and an edge S4 parallel to the right boundary U2 of the display area DA.

[0104] The first internal sub-pixel IF1 can be arranged in the display area DA. In an exemplary embodiment, the first internal sub-pixel IF1 may not be the first neighboring sub-pixel OF1, but rather the first sub-pixel F1. In another exemplary embodiment, the first neighboring sub-pixel OF1 may be arranged to surround the first internal sub-pixel IF1.

[0105] As described above, the pixel defining layer 29 can define the region of the sub-pixel F described above. In an exemplary embodiment, the pixel defining layer 29 can be arranged in the display area DA and the non-display area NDA. For example, in an exemplary embodiment, the pixel defining layer 29 can define the regions of the first neighboring sub-pixel OF1 and the first inner sub-pixel IF1. Since the first neighboring sub-pixel OF1 is arranged adjacent to the non-display area NDA, the pixel defining layer 29 can be arranged in the non-display area NDA to define the region of the first neighboring sub-pixel OF1.

[0106] The first neighboring sub-pixels OF1 and the first inner sub-pixel IF1 of the same color can have different shapes in the planar diagram. Specifically, the first upper sub-pixel OF1-1, the first right sub-pixel OF1-2, and the first intersecting sub-pixel OF1-3 can have shapes in the planar diagram that are different from the shape of the first inner sub-pixel IF1. For example, in an exemplary embodiment, the first upper sub-pixel OF1-1 and the first right sub-pixel OF1-2 can have pentagonal shapes in the planar diagram. Since the first inner sub-pixel IF1 can have a square shape in the planar diagram, the first upper sub-pixel OF1-1, the first right sub-pixel OF1-2, and the first inner sub-pixel IF1 can have different shapes in the planar diagram. In another exemplary embodiment, the first intersecting sub-pixel OF1-3 can have a hexagonal shape in the planar diagram. Since the first inner sub-pixel IF1 can have a square shape in the planar diagram, the first inner sub-pixel IF1 can have a shape in the planar diagram that is different from the shape of the first intersecting sub-pixel OF1-3.

[0107] Although not shown in the accompanying drawings, similar to the first sub-pixel F1, the second sub-pixel F2 may include a second neighboring sub-pixel and a second inner sub-pixel.

The chamfered third vertex ST3 of the third neighboring sub-pixel OF3 may be a portion overlapping the non-display area NDA. Multiple third neighboring sub-pixels OF3 may be arranged to be adjacent to the non-display area NDA and spaced apart from each other. Similar to the first inner sub-pixel IF1, the third inner sub-pixel IF3 may be arranged in the display area DA.

[0109] From another perspective, the first opening OP1 (see...) Figure 3 The first opening OP1 can be arranged in the display area DA to correspond to the first sub-pixel F1. The first opening OP1 may include a first adjacent opening OOP1 and a first internal opening IOP1. The first adjacent opening OOP1 and the first internal opening IOP1 may have different shapes in the plan view.

[0110] In an exemplary embodiment, the first adjacent opening OOP1 and the first internal opening IOP1 may be arranged in the display area DA. The first adjacent opening OOP1 may be arranged in the display area DA to be adjacent to the non-display area NDA. In another exemplary embodiment, the first adjacent opening OOP1 may be arranged in the display area DA to be adjacent to the boundary between the non-display area NDA and the display area DA. In yet another exemplary embodiment, the first adjacent opening OOP1 may be arranged in the display area DA to be adjacent to the boundary of the display area DA. Hereinafter, for ease of description, the case where the first adjacent opening OOP1 is arranged in the display area DA to be adjacent to the non-display area NDA will be described in detail.

[0111] The first adjacent opening OOP1 may have a polygonal shape. In an exemplary embodiment, the first adjacent opening OOP1 may have a pentagonal shape. In another exemplary embodiment, the first adjacent opening OOP1 may have a hexagonal shape. However, as described above, the shape of the first adjacent opening OOP1 is not limited to pentagonal or hexagonal.

[0112] The first adjacent opening OOP1 may include a first upper opening OOP1-1, a first right opening OOP1-2, and a first intersecting opening OOP1-3.

[0113] The first upper opening OOP1-1 may include an edge parallel to the boundary of the display area DA. In an exemplary embodiment, the first upper opening OOP1-1 may include an edge S3 parallel to a second direction. In another exemplary embodiment, the first upper opening OOP1-1 may include an edge S3 parallel to the upper boundary U1 of the display area DA. However, for ease of description, the case where the first upper opening OOP1-1 includes an edge S3 parallel to the upper boundary U1 of the display area DA will be described in detail below.

[0114] Multiple first upper openings OOP1-1 can be arranged to be adjacent to and spaced apart from the non-display area NDA. For example, in an exemplary embodiment, the first upper openings OOP1-1 can be arranged to be parallel to and spaced apart from the upper boundary U1 of the display area DA. In another exemplary embodiment, the first upper openings OOP1-1 can be arranged to be adjacent to the non-display area NDA, parallel to the second direction, and spaced apart from each other.

[0115] Similar to the first upper opening OOP1-1, the first right opening OOP1-2 may also include an edge parallel to the boundary of the display area DA. Specifically, the first right opening OOP1-2 may include an edge S4 parallel to the right boundary U2 of the display area DA. Multiple first right openings OOP1-2 may be arranged to be adjacent to and spaced apart from the non-display area NDA. Specifically, the first right openings OOP1-2 may be arranged to be adjacent to the non-display area NDA, parallel to the right boundary U2 of the display area DA, and spaced apart from each other.

[0116] In an exemplary embodiment, the first intersecting opening OOP1-3 may be defined within the display area DA. The first intersecting opening OOP1-3 may include at least two edges parallel to the boundaries of the display area DA. For example, in an exemplary embodiment, the first intersecting opening OOP1-3 may include an edge parallel to a second direction and an edge parallel to a first direction. In another exemplary embodiment, the first intersecting opening OOP1-3 may include an edge S3 parallel to the upper boundary U1 of the display area DA and an edge S4 parallel to the right boundary U2 of the display area DA.

[0117] The first internal opening IOP1 can be arranged in the display area DA. In an exemplary embodiment, the first internal opening IOP1 may not be the first adjacent opening OOP1, but rather the first opening OP1. In another exemplary embodiment, the first adjacent opening OOP1 may be arranged to surround the first internal opening IOP1.

[0118] The first adjacent opening OOP1 and the first inner opening IOP1, each defining a region that implements the same color as the first sub-pixel F1, can have different shapes in the planar view. Specifically, the first upper opening OOP1-1, the first right opening OOP1-2, and the first intersecting opening OOP1-3 can have shapes different from the shape of the first inner opening IOP1. For example, in an exemplary embodiment, the first upper opening OOP1-1 and the first right opening OOP1-2 can have pentagonal shapes in the planar view. Since the first inner opening IOP1 has a square shape in the planar view, the first upper opening OOP1-1, the first right opening OOP1-2, and the first inner opening IOP1 can have different shapes in the planar view. In another exemplary embodiment, the first intersecting opening OOP1-3 can have a hexagonal shape in the planar view. Since the first inner opening IOP1 can have a square shape in the planar view, the first inner opening IOP1 can have a shape different from the shape of the first intersecting opening OOP1-3 in the planar view.

[0119] Although not shown in the accompanying drawings, similar to the first opening OP1, the second opening OP2 may include a second adjacent opening and a second internal opening. Similar to the first adjacent opening OOP1, the second adjacent opening may be arranged in the display area DA adjacent to the non-display area NDA. Similar to the first upper opening OOP1-1, the second adjacent opening may include an edge parallel to the lower boundary of the display area DA. Multiple second adjacent openings may be arranged adjacent to the non-display area NDA and spaced apart from each other. Similar to the first internal opening IOP1, the second internal opening may be arranged in the display area DA.

[0120] Similar to the first opening OP1 or the second opening OP2, the third opening OP3 may include a third adjacent opening OOP3 and a third internal opening IOP3. Similar to the first adjacent opening OOP1, the third adjacent opening OOP3 may be arranged in the display area DA adjacent to the non-display area NDA. Similar to the first upper opening OOP1-1 or the first right opening OOP1-2, the third adjacent opening OOP3 may include an edge parallel to the left boundary U3 or the lower boundary of the display area DA. Multiple third adjacent openings OOP3 may be arranged adjacent to the non-display area NDA and spaced apart from each other. Similar to the first internal opening IOP1, the third internal opening IOP3 may be arranged in the display area DA.

[0121] In the scenario described above, when a user views the display device 20, the light blurring caused by the sub-pixels in the display area DA that are adjacent to the non-display area NDA can be eliminated.

[0122] like Figure 5A and Figure 5BAs shown, when subpixel F is tilted, the first neighboring subpixel OF1 and the first inner subpixel IF1 can be arranged to have the same shape in the plan view. In this case, the display area DA can be arranged alternately with the non-display area NDA to have a jagged shape TH.

[0123] refer to Figure 5A and Figure 5B The upper boundary U1 and right boundary U2 of the display area DA may overlap with the first neighboring sub-pixel OF1. The left boundary U3 of the display area DA may overlap with the third neighboring sub-pixel. The lower boundary U4 of the display area DA may overlap with at least one of the second and third neighboring sub-pixels. At the upper boundary U1 and right boundary U2 of the display area DA, blue light can be emitted due to the first neighboring sub-pixel OF1. At the left boundary U3 of the display area DA, red light can be emitted due to the third neighboring sub-pixel. At the lower boundary U4 of the display area DA, at least one selected from red, yellow, and green light can be emitted due to the second or third neighboring sub-pixel.

[0124] To minimize this phenomenon, in the illustrated exemplary embodiment, neighboring sub-pixels and inner sub-pixels implementing the same color can have different shapes in the planar view. Additionally, the neighboring openings and inner openings that each define a region implementing a sub-pixel F of the same color can have different shapes in the planar view. In the planar view, since the shapes of the neighboring sub-pixels in the display area DA adjacent to the non-display area NDA are different from the shapes of the inner sub-pixels, light blurring can be eliminated.

[0125] Figure 6 This is a plan view of another exemplary embodiment of sub-pixel F. Figure 6 middle, Figure 3 and Figure 4B The same reference numerals in the figures refer to the same elements, and therefore descriptions of the same elements will be omitted.

[0126] refer to Figure 6 The first upper sub-pixel OF1-1' may have the same size as the first inner sub-pixel IF1 in the planar diagram. In an exemplary embodiment, the size OS1 of the first upper sub-pixel OF1-1' may be the same as the size IS1 of the first inner sub-pixel IF1. In another exemplary embodiment, the first right sub-pixel may have the same size as the first inner sub-pixel IF1. In another exemplary embodiment, the first intersecting sub-pixel may have the same size as the first inner sub-pixel IF1. Hereinafter, for ease of description, the case where the size OS1 of the first upper sub-pixel OF1-1' is the same as the size IS1 of the first inner sub-pixel IF1 is described in detail.

[0127] In an exemplary embodiment, a first center sub-pixel CF1 may be included, which is arranged to be adjacent to and face the first upper sub-pixel OF1-1' and the first inner sub-pixel IF1, respectively. The shortest distance L1 from the boundary of the first upper sub-pixel OF1-1' to the boundary of the first center sub-pixel CF1 may be different from the shortest distance L2 from the boundary of the first inner sub-pixel IF1 to the boundary of the first center sub-pixel CF1. Specifically, the shortest distance L1 from the boundary of the first upper sub-pixel OF1-1' to the boundary of the first center sub-pixel CF1 may be less than the shortest distance L2 from the boundary of the first inner sub-pixel IF1 to the boundary of the first center sub-pixel CF1.

[0128] Similar to the description above, the second neighboring sub-pixel can have the same size as the second inner sub-pixel in the planar diagram. Additionally, a second center sub-pixel may be included, arranged to be adjacent to and face both the second neighboring sub-pixel and the second inner sub-pixel. The shortest distance from the boundary of the second neighboring sub-pixel to the boundary of the second center sub-pixel may differ from the shortest distance from the boundary of the second inner sub-pixel to the boundary of the second center sub-pixel. Specifically, the shortest distance from the boundary of the second neighboring sub-pixel to the boundary of the second center sub-pixel may be less than the shortest distance from the boundary of the second inner sub-pixel to the boundary of the second center sub-pixel.

[0129] The third neighboring sub-pixel OF3' can have the same size as the third inner sub-pixel IF3 in the planar diagram. Additionally, a third center sub-pixel CF3 can be included, arranged to be adjacent to and facing both the third neighboring sub-pixel OF3' and the third inner sub-pixel IF3. The shortest distance L3 from the boundary of the third neighboring sub-pixel OF3' to the boundary of the third center sub-pixel CF3 can be different from the shortest distance L4 from the boundary of the third inner sub-pixel IF3 to the boundary of the third center sub-pixel CF3. Specifically, the shortest distance L3 from the boundary of the third neighboring sub-pixel OF3' to the boundary of the third center sub-pixel CF3 can be less than the shortest distance L4 from the boundary of the third inner sub-pixel IF3 to the boundary of the third center sub-pixel CF3.

[0130] From another perspective, the first upper opening OOP1-1' can have the same size as the first inner opening IOP1 in the plan view. In an exemplary embodiment, the size OS1 of the first upper opening OOP1-1' can be the same as the size IS1 of the first inner opening IOP1. In another exemplary embodiment, the first right opening can have the same size as the first inner opening IOP1. In another exemplary embodiment, the first intersecting opening can have the same size as the first inner opening IOP1. Hereinafter, for ease of description, the case where the size OS1 of the first upper opening OOP1-1' is the same as the size IS1 of the first inner opening IOP1 is described in detail.

[0131] In an exemplary embodiment, a first central opening COP1 may be defined as being arranged adjacent to and facing the first upper opening OOP1-1' and the first inner opening IOP1, respectively. The shortest distance L1 from the boundary of the first upper opening OOP1-1' to the boundary of the first central opening COP1 may be different from the shortest distance L2 from the boundary of the first inner opening IOP1 to the boundary of the first central opening COP1. Specifically, the shortest distance L1 from the boundary of the first upper opening OOP1-1' to the boundary of the first central opening COP1 may be less than the shortest distance L2 from the boundary of the first inner opening IOP1 to the boundary of the first central opening COP1.

[0132] Similar to the above description, the second adjacent opening may have the same size as the second inner opening in the plan view. Additionally, a second central opening may be defined, arranged adjacent to and facing both the second adjacent opening and the second inner opening. The shortest distance from the boundary of the second adjacent opening to the boundary of the second central opening may differ from the shortest distance from the boundary of the second inner opening to the boundary of the second central opening. Specifically, the shortest distance from the boundary of the second adjacent opening to the boundary of the second central opening may be less than the shortest distance from the boundary of the second inner opening to the boundary of the second central opening.

[0133] The third adjacent opening OOP3' can have the same size as the third inner opening IOP3 in the plan view. Additionally, a third central opening COP3 can be defined, arranged to be adjacent to and facing both the third adjacent opening OOP3' and the third inner opening IOP3. The shortest distance L3 from the boundary of the third adjacent opening OOP3' to the boundary of the third central opening COP3 can be different from the shortest distance L4 from the boundary of the third inner opening IOP3 to the boundary of the third central opening COP3. Specifically, the shortest distance L3 from the boundary of the third adjacent opening OOP3' to the boundary of the third central opening COP3 can be less than the shortest distance L4 from the boundary of the third inner opening IOP3 to the boundary of the third central opening COP3. The first vertex ST1' and the third vertex ST3' can be as described above. Figure 4B The first vertex ST1 and the third vertex ST3 shown are basically similar.

[0134] As described above, when neighboring subpixels have the same size as the inner subpixels in the planar diagram, light can be emitted uniformly in the display area DA adjacent to the non-display area NDA. Therefore, the possibility of brightness or color differences caused by uneven emission can be reduced.

[0135] Figure 7 This is a cross-sectional view of another exemplary embodiment of the display device 20. Figure 7 middle, Figure 2 The same reference numerals in the figures refer to the same elements, and therefore descriptions of the same elements will be omitted.

[0136] refer to Figure 7 The spacer P can be arranged between corresponding sub-pixels (e.g., first sub-pixel F1 and third sub-pixel F3). The spacer P can be arranged on the pixel defining layer 29, or it can be integral with the pixel defining layer 29. The spacer P can include the same or different material as the pixel defining layer 29.

[0137] The spacer P can take various forms. For example, in an exemplary embodiment, multiple spacers P can be included in the form of protrusions, and multiple spacers P can be arranged on the pixel defining layer 29 to be spaced apart from each other. In another exemplary embodiment, a spacer P can be provided in the space between adjacent sub-pixels (e.g., first sub-pixel F1 and third sub-pixel F3). However, the spacer P is not limited to this.

[0138] Spacer P can be provided to prevent damage to substrate 21 in the method of manufacturing display device 20 according to the present invention. Mask assemblies can be used in the method of manufacturing display device 20. Since the mask assemblies are introduced into the openings of pixel defining layer 29 or bonded to pixel defining layer 29, dent defects may occur when each mask assembly is damaged or a portion of substrate 21 is destroyed during deposition of deposited material on substrate 21. When each mask assembly is bonded to substrate 21, spacer P can be used to maintain space between the end of the opening region of pixel defining layer 29 and each mask assembly.

[0139] According to various exemplary embodiments, when the display device 20 is arranged in a vehicle or the like, external light reflection can be minimized and light blurring can be eliminated in the display device 20.

[0140] It should be understood that the exemplary embodiments described herein are to be considered descriptive in nature only and are not intended for limiting purposes. The description of features in each exemplary embodiment should typically be considered as applicable to other similar features in other exemplary embodiments. Although one or more exemplary embodiments have been described with reference to the accompanying drawings, those skilled in the art will understand that various modifications in form and detail may be made to the exemplary embodiments without departing from the spirit and scope defined by the appended claims.
