[0170] Reference Figure 8 , in an embodiment, a plurality of pixels PX are arranged in a first direction DR1 to form a plurality of pixel rows, and are arranged in a second direction DR2 to form a plurality of pixel columns PXL. The plurality of pixels PX are formed in a matrix form. For example, when the number of the plurality of pixels PX is m×k, where m and k are each an integer of 2 or more, the plurality of pixels PX are arranged in m pixel rows and k pixel columns. The k pixel columns are labeled PXL1, PXL2... PXLk.
[0171] Each of the pixel columns PXL includes a plurality of pixels PX. The pixels PX of each pixel column PXL are arranged in a second direction DR2. For ease of description, although only the leftmost first pixel column PXL1 and the second pixel column PXL2 adjacent to the first pixel column PXL1 are described, this description equally applies to the nth pixel column PXLn, where n is an integer of 2 or greater, and is not limited to any one embodiment.
[0172] The pixels PX of the first pixel column PXL1 may be defined as first pixels PX1, and the pixels PX of the second pixel column PXL2 may be defined as second pixels PX2. The plurality of first pixels PX1 and second pixels PX2 include first light-emitting elements (or first-color light-emitting elements) PXB-1a, PXB-1b, PXB-2a, and PXB-2b, second light-emitting elements (or second-color light-emitting elements) PXR-1a, PXR-1b, PXR-2a, and PXR-2b, and third light-emitting elements (or third-color light-emitting elements) PXG-1a, PXG-1b, PXG-2a, and PXG-2b.

[0176] The arrangements of the first light-emitting elements PXB-1a and PXB-1b, the second light-emitting elements PXR-1a and PXR-1b, and the third light-emitting elements PXG-1a and PXG-1b of the first pixel PX1 and the arrangements of the first light-emitting elements PXB-2a and PXB-2b, the second light-emitting elements PXR-2a and PXR-2b, and the third light-emitting elements PXG-2a and PXG-2b of the second pixel PX2 are the same. In an embodiment of the inventive concept, the first color, the second color, and the third color are blue, red, and green, respectively, but are not necessarily limited thereto.
[0177] The arrangements of the first light-emitting element to the third light-emitting element are substantially the same in the pixel column PXL to reduce the visibility difference for distinguishing the emission regions corresponding to each pixel between adjacent pixel regions.
[0178] The first light-emitting elements PXB-1a and PXB-1b of the first pixel PX1 are spaced apart from the second light-emitting elements PXR-1a and PXR-1b of the first pixel PX1 in the first direction DR1. The first light-emitting elements PXB-1a and PXB-1b of the first pixel PX1 are spaced apart from the third light-emitting elements PXG-1a and PXG-1b of the first pixel PX1 in the first direction DR1. The second light-emitting elements PXR-1a and PXR-1b of the first pixel PX1 are spaced apart from the third light-emitting elements PXG-1a and PXG-1b of the first pixel PX1 in the second direction DR2.
[0179] As described above, the arrangement patterns of the light-emitting elements PXB-2a, PXB-2b, PXR-2a, PXR-2b, PXG-2a, and PXG-2b of the second pixel PX2 are the same as those of the light-emitting elements PXB-1a, PXB-1b, PXR-1a, PXR-1b, PXG-1a, and PXG-1b of the first pixel PX1. For example, the first light-emitting elements PXB-2a and PXB-2b of the second pixel PX2 are spaced apart from the second light-emitting elements PXR-2a and PXR-2b of the second pixel PX2 in the first direction DR1. The first light-emitting elements PXB-2a and PXB-2b of the second pixel PX2 are spaced apart from the third light-emitting elements PXG-2a and PXG-2b of the second pixel PX2 in the first direction DR1. The second light-emitting elements PXR-2a and PXR-2b of the second pixel PX2 are spaced apart from the third light-emitting elements PXG-2a and PXG-2b of the second pixel PX2 in the second direction DR2.
[0180] The second light-emitting elements PXR-1a and PXR-1b of the first pixel PX1 and the third light-emitting elements PXG-1a and PXG-1b of the first pixel PX1 are alternately arranged in the second direction DR2. The second light-emitting elements PXR-2a and PXR-2b of the second pixel PX2 and the third light-emitting elements PXG-2a and PXG-2b of the second pixel PX2 are alternately arranged in the second direction DR2.
[0181] Referring to the accompanying drawings, the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b, the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b, and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are shown in a planar rectangular shape with curved corners. However, these shapes are not necessarily limited thereto, and the planar shape of the light-emitting elements may have a square, rectangular, or other polygonal shape. For example, in an embodiment of the inventive concept, the corners of the shape of the light-emitting elements may be defined not only by straight lines but also by curves.
[0182] Use Figure 6 The above-described input sensor ISP uses includes a plurality of sensor lines SSL. In addition, use Figure 7 The above-described sensor conductive layer MTL uses includes a plurality of sensor lines SSL.
[0183] A plurality of sensor lines SSL are provided on a pixel defining layer PDL (see Figure 7 ). The sensor lines SSL are provided between a plurality of pixels PX. The sensor lines SSL are provided on the pixel defining layer PDL corresponding to the arrangement pattern of the light-emitting elements (see Figure 7) above. The sensor line SSL extends in the first direction DR1 or the second direction DR2.
[0184] The sensor line SSL includes a plurality of first line portions SSLa, a plurality of second line portions SSLb, and a plurality of third line portions SSLc.
[0185] The plurality of first line portions SSLa pass between the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b and the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b, and between the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b. The first line portions SSLa extend in the second direction DR2. The first line portions SSLa include first-first line portions SSLa1 spaced apart from the second light-emitting elements PXR-1a and PXR-1b and the third light-emitting elements PXG-1a and PXG-1b in the first direction DR1. The first line portions SSLa also include first-second line portions SSLa2 that pass between the first light-emitting elements PXB-1a and PXB-1b and the second light-emitting elements PXR-1a and PXR-1b, and between the first light-emitting elements PXB-1a and PXB-1b and the third light-emitting elements PXG-1a and PXG-1b in the first pixel PX1 of the first pixel column PXL1. In addition, the first line portions SSLa further include first-third line portions SSLa3 that pass between the first light-emitting elements PXB-1a and PXB-1b and the second light-emitting elements PXR-2a and PXR-2b, and between the first light-emitting elements PXB-1a and PXB-1b and the third light-emitting elements PXG-2a and PXG-2b in the second pixel PX2. In addition, the first line portions SSLa include first-fourth line portions SSLa4 that pass between the first light-emitting elements PXB-2a and PXB-2b and the second light-emitting elements PXR-2a and PXR-2b, and between the first light-emitting elements PXB-2a and PXB-2b and the third light-emitting elements PXG-2a and PXG-2b in the second pixel PX2 of the second pixel column PXL2. This description applies to the pixels PX in the remaining pixel columns PXL.
[0186] The plurality of second line portions SSLb pass between the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b adjacent to each other along the second direction DR2. The second line portions SSLb extend in the first direction DR1. The second line portions SSLb connect the first line portions SSLa adjacent in the first direction DR1. The first end and the second end of each of the second line portions SSLb are in contact with the adjacent first line portions SSLa.
[0187] The second line portion SSLb overlaps with the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b in the second direction DR2. The second line portion SSLb does not overlap with the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b in the second direction DR2.
[0188] At least one of the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, or PXB-2b is disposed between adjacent second line portions SSLb along the second direction DR2. For example, the region SAA located between the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b includes a first region SAA1 and a second region SSA2. The first region SAA1 is a position where the second line portion SSLb is not disposed, or a region that does not overlap with the second line portion SSLb. The second region SSA2 is a position where one of the second line portions SSLb is disposed, or a region that overlaps with the second line portion SSLb.
[0189] In the drawings, although two of the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b are shown as being disposed between adjacent second line portions SSLb, the embodiment is not necessarily limited thereto. For example, in some embodiments, three or more of the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b are disposed between adjacent second line portions SSLb.
[0190] The second line portion SSLb includes a first sub-line portion SSLb1 and a second sub-line portion SSLb2. The first sub-line portion SSLb1 is disposed in the first pixel column PXL1, and the second sub-line portion SSLb2 is disposed in the second pixel column PXL2. For example, the first sub-line portion SSLb1 is disposed between the first light-emitting elements PXB-1a and PXB-1b of the first pixel PX1, and the second sub-line portion SSLb2 may be disposed between the first light-emitting elements PXB-2a and PXB-2b of the second pixel PX2. The first sub-line portion SSLb1 and the second sub-line portion SSLb2 overlap each other in the first direction DR1. However, the embodiment is not necessarily limited thereto, and in other embodiments, only a part of the first sub-line portion SSLb1 and a part of the second sub-line portion SSLb2 overlap each other in the first direction DR1.
[0191] A plurality of third line portions SSLc pass between those second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and those third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b that are adjacent in the second direction DR2. The third line portions SSLc extend in the first direction DR1. The third line portions SSLc connect the first line portions SSLa that are adjacent in the first direction DR1. The first end and the second end of each of the third line portions SSLc are in contact with the adjacent first line portions SSLa.
[0192] The third line portions SSLc overlap with the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b in the second direction DR2. The third line portions SSLc do not overlap with the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b in the second direction DR2.
[0193] Some portions of the third line portions SSLc overlap with the second line portions SSLb in the first direction DR1. The remaining portions of the third line portions SSLc do not overlap with the second line portions SSLb in the first direction DR1.
[0194] At least one of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, or PXR-2b and at least one of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, or PXG-2b are provided between the third line portions SSLc that are adjacent in the second direction DR2. The number of light-emitting elements positioned between the adjacent third line portions SSLc in the second direction DR2 is odd. The number of light-emitting elements between the third line portions SSLc that are adjacent in the second direction DR2 is one greater than the number of other light-emitting elements between the second line portions SSLb that are adjacent in the second direction DR2.
[0195] Reference Figure 8 , in the first pixel column PXL1, two second light-emitting elements and one third light-emitting element are provided between some of the third line portions SSLc that are adjacent in the second direction DR2. In addition, one second light-emitting element and two third light-emitting elements are provided between other third line portions SSLc that are adjacent in the second direction DR2.
[0196] A light-emitting element group having two second light-emitting elements and one third light-emitting element disposed between third line portions SSLc adjacent in the second direction DR2 can be defined as a first light-emitting element group, and a light-emitting element group having one second light-emitting element and two third light-emitting elements disposed between third line portions SSLc adjacent in the second direction DR2 can be defined as a second light-emitting element group. Each of the first light-emitting element group and the second light-emitting element group is provided in a plurality. The first light-emitting element group and the second light-emitting element group are alternately arranged in the second direction DR2. This arrangement is similarly applied to the second pixel column PXL2 and other pixel columns PXL.
[0197] In the first light-emitting element group, the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are closer to the third line portion SSLc than the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b. The second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are adjacent to the third line portion SSLc, and thus, when the user views in the second direction DR2 (such as the vertical direction), the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are covered by the third line portion SSLc. This will be described below with reference to Figure 9 This is described.
[0198] In the second light-emitting element group, the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are closer to the third line portion SSLc than the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b.
[0199] The first light-emitting element group and the second light-emitting element group are alternately arranged in the second direction DR2, and thus, the total number of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b is substantially the same as the total number of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b. For example, the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b among the light-emitting elements adjacent to the third line portion SSLc in one direction have the same number as the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b.
[0200] As a result, when the user views in a direction parallel to the second direction DR2 (such as the upward direction), and when the user views the display device DD in a direction opposite to the second direction DR2 (such as the downward direction), there is no difference in display quality. As a result, when the user views the display device DD in the second direction DR2 (such as the vertical direction), a difference in display quality can be prevented from occurring.
[0201] Since the number of the first light-emitting element to the third light-emitting element covered in the first direction DR1 (such as, left and right directions) is the same, when the user views in the first direction DR1 (such as, left or right direction), there is no difference in the display quality of the display device DD.
[0202] The third line portion SSLc includes a third sub-line portion SSLc1 and a fourth sub-line portion SSLc2. The third sub-line portion SSLc1 is disposed in the first pixel column PXL1, and the fourth sub-line portion SSLc2 is disposed in the second pixel column PXL2. For example, the third sub-line portion SSLc1 is disposed between the second light-emitting elements PXR-1a and PXR-1b and the third light-emitting elements PXG-1a and PXG-1b of the first pixel PX1, and the fourth sub-line portion SSLc2 is disposed between the second light-emitting elements PXR-2a and PXR-2b and the third light-emitting elements PXG-2a and PXG-2b of the second pixel PX2. The third sub-line portion SSLc1 and the fourth sub-line portion SSLc2 overlap each other in the first direction DR1. However, the embodiment is not necessarily limited thereto, and in other embodiments, only a part of the third sub-line portion SSLc1 and a part of the fourth sub-line portion SSLc2 overlap each other in the first direction DR1.
[0203] According to an embodiment of the inventive concept, the widths of the first line portion SSLa, the second line portion SSLb, and the third line portion SSLc are the same. However, the embodiment is not necessarily limited thereto, and in other embodiments, the widths of the second line portion SSLb and the third line portion SSLc are different from each other.
[0204] Figure 9 It shows how a part of a pixel is covered by a sensor line according to the direction in which the user looks. For ease of description, only a part of the display module DM is shown in Figure 9 .
[0205] Referring to Figure 9 , depending on the direction or angle at which the user views the display device, a part of the pixel PX is covered by the sensor line SSL.
[0206] Referring to the drawings, when the user views the display device at a first angle θ1, the pixel PX is not covered by the sensor line SSL. When the user views the display device at a second angle θ2, the pixel PX is covered by the sensor line SSL. The second angle θ2 is greater than the first angle θ1.
[0207] The first angle θ1 and the second angle θ2 vary depending on the direction or angle at which the user views the display device. In addition, the first angle θ1 and the second angle θ2 vary depending on whether the covered portion corresponds to the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b (see Figure 8 ), the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b (see Figure 8 ), or the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b (see Figure 8 ).
[0208] For the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b (see Figure 8 ), when compared with the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b (see Figure 8 ) and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b (see Figure 8 ), the distance between adjacent first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b is greater than the distance between adjacent light-emitting elements among the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b (see Figure 8 ) and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b (see Figure 8 ). Therefore, for the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b (see Figure 8 ), the second angle θ2 is about 60 degrees or greater. For the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b (see Figure 8 ) and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b (see Figure 8 ), the second angle θ2 is less than about 60 degrees.
[0209] Therefore, as used below Figure 10As described, the number of third line portions SSLc is less than the number of second line portions SSLb, or the third line portions SSLc are omitted to minimize or prevent the second light emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b from being covered in the second direction DR2. As a result, compared to the first light emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b in the display device, the coverage of the second light emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b is minimized to improve the overall display quality of the display device.
[0210] Figures 10 to 15 is a plan view of display modules DMa, DMb, DMc, DMd, DMe, DMf according to an embodiment of the inventive concept.
[0211] Hereinafter, in the description Figures 10 to 15 when, components similar to those used Figure 8 described have the same or similar reference numerals, and their repeated descriptions may be omitted or generalized.
[0212] Referring to Figure 10 , in an embodiment, a third line portion SSLc is omitted from a plurality of sensor lines SSL. The third line portion SSLc is omitted to prevent the second light emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b from being covered. As a result, when a user views the display device in a direction parallel to the second direction DR2 and when the user views the display device in a direction opposite to the second direction DR2, there is no difference in the display quality. As a result, when the user views the display device in the second direction DR2, a difference in display quality can be prevented.
[0213] Referring to Figure 11 , in an embodiment, two second light emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and three third light emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are disposed between third line portions SSLc adjacent to each other along the second direction DR2. The second light emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are alternately arranged in the second direction DR2.
[0214] In addition, three second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and two third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are provided between other third line portions SSLc. The second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are alternately arranged in the second direction DR2.
[0215] A light-emitting element group in which two second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and three third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are provided between third line portions SSLc adjacent in the second direction DR2 can be defined as a first light-emitting element group, and a light-emitting element group in which three second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and two third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are provided between third line portions SSLc adjacent in the second direction DR2 can be defined as a second light-emitting element group. The first light-emitting element group and the second light-emitting element group are alternately arranged in the second direction DR2.
[0216] In the second light-emitting element group, the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b may be closer to the third line portion SSLc than the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b. The second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are adjacent to the third line portion SSLc, and thus, when the user views in the second direction DR2 (such as the vertical direction), the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are covered by the third line portion SSLc.
[0217] In the first light-emitting element group, the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are closer to the third line portion SSLc than the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b.
[0218] The first light-emitting element group and the second light-emitting element group are alternately arranged in the second direction DR2. Therefore, the total number of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b covered in the second direction DR2 is substantially the same as the total number of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b covered in the second direction DR2. As a result, when the user views in a direction parallel to the second direction DR2 (such as the upward direction), and when the user views in a direction opposite to the second direction DR2 (such as the downward direction), there is no difference in the display quality. As a result, when the user views the display device in the second direction DR2 (such as the vertical direction), a difference in the display quality can be prevented from occurring.
[0219] Since the number of the first light-emitting element to the third light-emitting element covered in the first direction DR1 (such as the left and right directions) is the same, when the user views in the first direction DR1 (such as the left and right directions), there is no difference in the display quality.
[0220] Reference Figure 12 and Figure 13 In the embodiment, one of the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, or PXB-2b is disposed between second line portions SSLb adjacent to each other in the second direction DR2. The first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b and the second line portions SSLb are alternately arranged in the second direction DR2. The number of the second line portions SSLb increases, and thus, signals are easily transmitted through the sensor line SSL.
[0221] According to Figure 12 In the embodiment shown, at least one of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, or PXR-2b and at least one of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, or PXG-2b are disposed between third line portions SSLc adjacent to each other in the second direction DR2.
[0222] According to Figure 13In the illustrated embodiment, the third line portion SSLc is omitted from the plurality of sensor lines SSL. The omission of the third line portion SSLc prevents the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b from being covered. As a result, there is no difference in display quality when the user views the display device in a direction parallel to the second direction DR2 and when the user views the display device in a direction opposite to the second direction DR2. As a result, when the user views the display device in the second direction DR2, a difference in display quality can be prevented from occurring.
[0223] In addition, even if the third line portion SSLc is omitted, the number of the second line portions SSLb increases, and thus, signals can be easily transmitted through the sensor lines SSL.
[0224] Reference Figure 14 , in the embodiment, the third sub-line portion SSLc1 and the fourth sub-line portion SSLc2 do not overlap each other in the first direction DR1.
[0225] One of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, or PXR-2b and two of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are provided between some of the third sub-line portions SSLc1 adjacent to each other in the second direction DR2 and some of the fourth sub-line portions SSLc2. In addition, two of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and one of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, or PXG-2b are provided between other third sub-line portions SSLc1 and other fourth sub-line portions SSLc2.
[0226] A light-emitting element group including one of the second light-emitting elements PXR-1a or PXR-1b and two of the third light-emitting elements PXG-1a and PXG-1b provided between the third sub-line portions SSLc1 adjacent to each other in the second direction DR2 can be defined as a first light-emitting element group, and a light-emitting element group including two of the second light-emitting elements PXR-1a and PXR-1b and one of the third light-emitting elements PXG-1a or PXG-1b provided between the third sub-line portions SSLc1 adjacent to each other in the second direction DR2 can be defined as a second light-emitting element group. The first light-emitting element group and the second light-emitting element group are alternately provided in the second direction DR2.
[0227] A light-emitting element group provided with one second light-emitting element PXR-2a or PXR-2b and two third light-emitting elements PXG-2a and PXG-2b between fourth sub-line portions SSLc2 adjacent in the second direction DR2 can be defined as a third light-emitting element group, and a light-emitting element group provided with two second light-emitting elements PXR-2a and PXR-2b and one third light-emitting element PXG-2a or PXG-2b between fourth sub-line portions SSLc2 adjacent in the second direction DR2 can be defined as a fourth light-emitting element group. The third light-emitting element group and the fourth light-emitting element group are alternately arranged in the second direction DR2.
[0228] The first light-emitting element group and the second light-emitting element group partially overlap with the third light-emitting element group in the first direction DR1. In addition, the first light-emitting element group and the second light-emitting element group partially overlap with the fourth light-emitting element group in the first direction DR1.
[0229] In the second light-emitting element group and the fourth light-emitting element group, the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are closer to the third line portion SSLc than the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b. The second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are adjacent to the third sub-line portion SSLc1 or the fourth sub-line portion SSLc2, and thus, when observed in the second direction DR2 (such as the vertical direction), the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b are covered by the third sub-line portion SSLc1 and the fourth sub-line portion SSLc2.
[0230] In the first light-emitting element group and the third light-emitting element group, the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b are closer to the third sub-line portion SSLc1 and the fourth sub-line portion SSLc2 than the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b.
[0231] The first light-emitting element group and the second light-emitting element group are alternately arranged in the second direction DR2, and the third light-emitting element group and the fourth light-emitting element group are alternately arranged in the second direction DR2. Therefore, the total number of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b covered in the second direction DR2 and the total number of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b covered in the second direction DR2 are substantially the same. For example, among the light-emitting elements each adjacent to the third sub-line portion SSLc1 and the fourth sub-line portion SSLc2 in the first pixel column PXL1 or the second pixel column PXL2, the number of the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b is the same as the number of the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b.
[0232] As a result, when the user views in a direction parallel to the second direction DR2 (such as the upward direction), and when the user views in a direction opposite to the second direction DR2 (such as the downward direction), there is no difference in the display quality. As a result, when the user views the display device in the second direction DR2 (such as the vertical direction), a difference in the display quality can be prevented from occurring.
[0233] Since the number of the first light-emitting element to the third light-emitting element covered in the first direction DR1 (such as the left and right directions) is the same, when the user views in the first direction DR1 (such as the left and right directions), there is no difference in the display quality.
[0234] In the drawings, although the first light-emitting element group to the fourth light-emitting element group are shown as including three light-emitting elements, the embodiment is not necessarily limited thereto. For example, in some embodiments, the first light-emitting element group to the fourth light-emitting element group include an odd number of light-emitting elements. For example, in an embodiment, the light-emitting element group includes 5 or 7 light-emitting elements.
[0235] In addition, in some embodiments, the number of light-emitting elements included in each light-emitting element group is different from each other.
[0236] Reference Figure 15 , in an embodiment, the distance G1 between the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b adjacent to each other in the second direction DR2 is greater than the distance G2 between the light-emitting elements adjacent to each other in the second direction DR2 among the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b and the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b. In an embodiment, the first light-emitting opening PX-OP1 adjacent to each other in the second direction DR2 (seeFigure 8 ) is greater than the distance between adjacent light-emitting openings among the second light-emitting opening PX-OP2 (see Figure 8 ) and the third light-emitting opening PX-OP3 (see Figure 8 ). In addition, the distance between the first light-emitting elements PXB-1a, PXB-1b, PXB-2a, and PXB-2b and the second line portion SSLb in the second direction DR2 is greater than or equal to the distance between the second light-emitting elements PXR-1a, PXR-1b, PXR-2a, and PXR-2b or the third light-emitting elements PXG-1a, PXG-1b, PXG-2a, and PXG-2b and the third line portion SSLc in the second direction DR2.
[0237] According to an embodiment of the inventive concept, the width of each of the second line portions SSLb is greater than or equal to the width of each of the third line portions SSLc. Each of the second line portions SSLb has a wide width, and the sum of the widths of all the sensor lines SSL is widened. As a result, the reliability of signal transmission of the sensor lines SSL is ensured.
[0238] The display device according to an embodiment of the inventive concept provides consistent display quality even when a user views the display panel in the vertical and horizontal directions.
[0239] The display device according to an embodiment of the inventive concept ensures symmetry in the vertical direction in the arrangement relationship of the line portions of the sensor.
[0240] The display device according to an embodiment of the inventive concept ensures symmetry in the left and right directions in the arrangement relationship of the line portions of the sensor.
