[0053] Hereinafter, a display device according to an embodiment of the inventive concept will be described with reference to the accompanying drawings.

[0054] Figure 1 is a perspective view of a display device DD according to an embodiment of the inventive concept. Figure 1 As shown, the display device DD may display an image through the display surface DD-IS. In a plan view, the display surface DD-IS may have a rectangular shape having a pair of short sides extending in a first direction DR1 and a pair of long sides extending in a second direction DR2 intersecting the first direction DR1. However, it is not necessarily limited thereto, and the display surface DD-IS may have various shapes such as a circle or a polygon.

[0055] In this embodiment, the third direction DR3 may be defined as a direction substantially perpendicular to a plane defined by the first direction DR1 and the second direction DR2. The front (or upper) surface and the rear (or lower) surface of each member constituting the display device DD may be opposite to each other in the third direction DR3, and the normal direction of each of the front surface and the rear surface may be substantially parallel to the third direction DR3. The separation distance between the front surface and the rear surface defined along the third direction DR3 may correspond to the thickness of the member.

[0056] In the present specification, the expression "in a plan view" may be defined as being observed in the third direction DR3. That is, the expression "in a plan view" may be described based on a plane defined by the first direction DR1 and the second direction DR2. In the present specification, the expression "on a cross section" may be defined as being observed in the first direction DR1 or the second direction DR2. The directions indicated by the first direction to the third directions DR1, DR2, and DR3 are relative concepts and may be converted into other directions.

[0057] In the embodiment of the inventive concept, a display device DD having a flat display surface is illustrated, but the embodiment of the inventive concept is not necessarily limited thereto. The display device DD may include a curved display surface or a three-dimensional display surface. For example, the three-dimensional display surface may include a plurality of display areas indicating directions different from each other, and may also include a bent display surface. According to this embodiment, the display device DD may be a flexible display device DD. The flexible display device DD may be a foldable display device that can be folded to a significant extent without breaking or otherwise being damaged.

[0061] The border area DD-NDA may at least partially surround the active area DD-DA. As used herein, the phrase "at least partially surround" is understood to mean that the surrounding element contacts the surrounded element on at least one side or part thereof, may contact the surrounded element on both sides, whether these sides are opposite sides or close sides, may contact the surrounded element on more than two sides, and may even completely surround the surrounded element. However, it is not necessary to be limited to this, and the shape of the border area DD-NDA may be modified. For example, the border area DD-NDA may be set only on one side of the active area DD-DA.

In addition, the plurality of grid lines may further include a third grid line ML3 extending in the second direction DR2. The third grid line ML3 may be disposed between two adjacent second grid lines ML2.

Each of the second grid lines ML2 may extend in the second direction DR2, and the second grid lines ML2 may be spaced apart from each other in the first direction DR1. The second grid lines ML2 may cross the first grid lines ML1 in a plan view and have an integral shape. In addition, each of the third grid lines ML3 may extend in the second direction DR2, and the third grid lines ML3 may be arranged in the first direction DR1 and the second direction DR2. The third grid lines ML3 may be arranged alternately with the second grid lines ML2 in the first direction DR1.

[0157] The mesh pattern MP may include first to third opening areas EOP1, EOP2, and EOP3 defined by first to third mesh lines ML1, ML2, and ML3.

The third opening area EOP3 may be surrounded by the first and second grid lines ML1 and ML2 .

[0158] In an embodiment of the inventive concept, the first to third opening regions EOP1, EOP2, and EOP3 may have different areas in a plan view. Figure 7In the embodiment of the inventive concept illustrated in FIG. 1 , on a plane defined by the first direction DR1 and the second direction DR2, the third opening area EOP3 may have the largest area among the first to third opening areas EOP1, EOP2, and EOP3, and the first opening area EOP1 may have the smallest area among the first to third opening areas EOP1, EOP2, and EOP3. The first opening area EOP1, the second opening area EOP2, and the third opening area EOP3 may be alternately formed along the second direction DR2. One third opening area EOP3 may overlap each of the first opening area EOP1 and the second opening area EOP2 in the second direction DR2.

[0159] The regions defining the first to third opening regions EOP1, EOP2, and EOP3 may be respectively aligned with the first to third light emitting regions LA1, LA2, and LA3 (see Figure 4A ) overlap. However, embodiments of the inventive concept are not necessarily limited thereto, and the areas of the first to third opening regions EOP1, EOP2, and EOP3 depend on the first to third light emitting regions LA1, LA2, and LA3 (see Figure 4A )'s shape etc.

[0160] Figure 7 The shape of the mesh pattern MP illustrated in FIG. 1 is an example, and the arrangement and shape of the first to third mesh lines ML1, ML2, and ML3 and the first to third opening areas EOP1, EOP2, and EOP3 in the mesh pattern MP may depend on the display panel 100 (see FIG. 1 ).

[0161] A cutting portion may be defined in at least one of the first grid line ML1, the second grid line ML2, and the third grid line ML3 included in each of the first sensing pattern SP1 and the second sensing pattern SP2. In an embodiment of the inventive concept, the first sensing pattern SP1 and the second sensing pattern SP2 adjacent thereto may be spaced apart and electrically insulated from each other, and the cutting portion may include a boundary cutting portion CT defined between the first sensing pattern SP1 and the second sensing pattern SP2.

[0162] For ease of explanation, Figure 7It is exemplarily illustrated that a boundary cutting portion CT having a constant distance is defined between the first sensing pattern SP1 and the second sensing pattern SP2. However, the shape of the boundary cutting portion CT is not necessarily limited thereto, and the boundary cutting portion CT may have a shape in which a portion of each of the first grid line ML1, the second grid line ML2, and the third grid line ML3 is removed.

[0163] Fig. 8A is an enlarged plan view of a partial area of ​​a display device according to an embodiment of the inventive concept. Fig. 8A Can be used with Figure 7 Corresponding to area AA. Figure 8B yes Fig. 8A An enlarged view of a portion of. Figure 8B Can be used with Fig. 8A Corresponding to area ZZ'.

[0164] Fig. 8A and Figure 8B The embodiments illustrated in the figure may have reference Figure 4A In an embodiment of the present inventive concept, the display device may include a plurality of light emitting areas LA1, LA2, and LA3 spaced apart from each other. In an embodiment of the present inventive concept, the first light emitting unit UA1 and the second light emitting unit UA2 may be adjacent to each other in each of the first direction DR1 and the second direction DR2.

[0165] In an embodiment of the inventive concept, the display device may include a plurality of grid lines ML and a plurality of protrusions BMP. The grid lines ML and the protrusions BMP may be included in the input sensor 200 (see Figure 5 ). The protrusion portion BMP may have a shape protruding inside the opening areas EOP1, EOP2, and EOP3 defined by the grid lines ML. The protrusion portion BMP may have a shape protruding from at least one of the grid lines ML into the opening areas EOP1, EOP2, and EOP3. Each of the protrusion portions BMP may be formed integrally with the grid lines ML.

[0166] The mesh lines ML and the protruding portions BMP may be aligned with the first conductive layer 220 (see Figure 5 ) and a second conductive layer 240 (see Figure 5 ) are disposed in the same layer. In an embodiment of the inventive concept, the mesh line ML and the protrusion BMP may be disposed in the same layer as the second conductive layer 240 (see Figure 5 ) are set on the same layer.

[0167] One embodiment may further include a cutting portion CTP defined in at least one of the mesh lines ML. The cutting portion CTP may be aligned with the first conductive layer 220 (see Figure 5) and a second conductive layer 240 (see Figure 5 ) are defined in the same layer. In an embodiment of the inventive concept, the cutting portion CTP may be defined in the same layer as the second conductive layer 240 (see Figure 5 ) is set in the grid line ML of the same layer. Fig. 8A In the embodiment illustrated in FIG. 1 , the cutting portion CTP may be defined in the third mesh line ML3 . However, embodiments of the inventive concept are not necessarily limited thereto, and the cutting portion CTP may be additionally defined in the first mesh line ML1 or the second mesh line ML2 .

[0168] In the display device according to the embodiment of the inventive concept, since the input sensor 200 (see Figure 5 ) includes a protruding portion BMP or a cutting portion CTP, so that the grid line ML or the boundary cutting portion CT (see Figure 7 ) is visible to the viewer.

[0169] In an embodiment of the inventive concept, the protrusion portion BMP may include a first protrusion portion BMP1 disposed between light emitting regions spaced apart from each other by a first distance DT1 in the first direction DR1, and a second protrusion portion BMP2 disposed between light emitting regions spaced apart from each other by a second distance DT2 in the first direction DR1. The first distance DT1 may be greater than the second distance DT2, and a plane area of ​​the first protrusion portion BMP1 may be greater than a plane area of ​​the second protrusion portion BMP2. The plane area of ​​the protrusion portion BMP corresponds to an area on a plane defined by the first direction DR1 and the second direction DR2.

[0170] In an embodiment of the inventive concept, as the separation distance between the light emitting regions LA1, LA2, and LA3 increases, the area of ​​the protrusion portion BMP disposed between the light emitting regions LA1, LA2, and LA3 spaced apart from each other may increase. In an embodiment of the inventive concept, as the distance between the light emitting regions spaced apart from each other in one direction increases, the planar area of ​​the protrusion portion disposed between the light emitting regions spaced apart from each other may increase.

[0171] refer to Fig. 8A , the first protrusion portion BMP1 may be disposed between the third light emitting area LA3 of the first light emitting unit UA1 and the third light emitting area LA3 of the second light emitting unit UA2. For example, the first protrusion portion BMP1 may be disposed in a portion where the separation distance between the light emitting areas is relatively large. For example, the first protrusion portion BMP1 may be disposed in a portion where the separation distance between the light emitting areas is relatively large. Figure 4A The first part of the description PT1 (see Figure 4AThe first protrusion portion BMP1 may not be disposed in the second portion PT2 where the separation distance between the light emitting regions is relatively small (see Figure 4A )middle.

[0172] In an embodiment of the inventive concept, the protrusion portion BMP may overlap the light emitting regions LA1, LA2, and LA3 in a direction in which a difference in separation distance between the light emitting regions LA1, LA2, and LA3 is large. Fig. 8A , the difference in separation distances between the light emitting regions LA1, LA2, and LA3 adjacent to each other in the first direction DR1 (the difference between the first distance DT1 and the second distance DT2) may be greater than the difference in separation distances between the light emitting regions LA1, LA2, and LA3 adjacent to each other in the second direction DR2. Therefore, the protrusion portion BMP may overlap the light emitting regions LA1, LA2, and LA3 in the first direction DR1. In addition, in an embodiment of the inventive concept, the protrusion portion BMP may not be disposed between the light emitting regions LA1, LA2, and LA3 adjacent to each other in the second direction DR2.

[0173] In an embodiment of the present invention, in order to reduce the degree to which the display quality is degraded by the viewing angle difference according to the separation distance between the light-emitting areas LA1, LA2 and LA3 adjacent to each other in the first direction DR1 (for example, the difference between the first distance DT1 and the second distance DT2), a first protrusion BMP1 having a relatively large size can be disposed between the light-emitting areas having a relatively large separation distance therebetween.

[0174] exist Fig. 8A and Figure 8B In the embodiment illustrated in FIG. 1 , the first protruding portion BMP1 may be disposed between the third color light emitting regions LA3 having a relatively large separation distance therebetween, and the third color light emitting regions LA3 have a relatively large separation distance therebetween. The third color light emitting regions LA3 may be blue light emitting regions. For example, the first protruding portion BMP1 may be disposed between the blue light emitting regions, and may be disposed, for example, at the first portion PT1 having a large separation distance between the blue light emitting regions (see FIG. 1 ). Figure 4A ). In addition, the second protrusion portion BMP2 may be disposed between the second color light emitting area LA2 and the first color light emitting area LA1. The second color light emitting area may be a green light emitting area, and the first color light emitting area may be a red light emitting area. Figure 4A In the case of a display device with the arrangement of the light-emitting units shown in the figure, the first protruding portion BMP1 can be disposed between blue light-emitting areas having a relatively large separation distance, and the second protruding portion BMP2 can overlap the first protruding portion BMP1 in the second direction DR2 between the green light-emitting area and the red light-emitting area.

[0175] For example, in a display device according to an embodiment of the present invention, by changing the size of a protrusion disposed between adjacent light-emitting areas according to the difference in the separation distance between the adjacent light-emitting areas, the degree to which the viewing angle affects the display quality according to the separation distance between the light-emitting areas can be reduced. Therefore, since the display device according to an embodiment of the present invention includes a protrusion having a relatively large area between light-emitting areas having a relatively large separation distance therebetween, the viewing angle characteristics of light emitted from the light-emitting area having a relatively large separation distance can be adjusted to a level similar to the viewing angle characteristics of light emitted from the light-emitting area having a relatively small separation distance. Therefore, the display device according to an embodiment of the present invention can exhibit excellent display quality because the color difference depending on the viewing angle is reduced even when the light-emitting areas are spaced at different distances from each other. This undesirable phenomenon in which an observer observes color differences in a display panel when the viewing angle changes is called visual color deviation.

[0176] In an embodiment of the inventive concept, the first protruding portion BMP1 and the second protruding portion BMP2 may overlap each other in the second direction DR2. In addition, in an embodiment of the inventive concept including the cutting portion CTP, the cutting portion CTP may overlap the second protruding portion BMP2 in the first direction DR1. Since the display device according to an embodiment of the inventive concept includes the first protruding portion BMP1, the second protruding portion BMP2, and the cutting portion CTP, the display device may exhibit excellent display quality and reduced color difference depending on the viewing angle.

[0177] In an embodiment of the present inventive concept, the grid line ML may be disposed between the light emitting areas LA1, LA2, and LA3. In an embodiment of the present inventive concept, the grid line ML may not overlap with the light emitting areas LA1, LA2, and LA3, and may be disposed on the pixel definition film PDL (see Figure 5 ). The display device according to an embodiment of the present invention includes an input sensor 200 (see Figure 5 ), the light emitted from the light emitting areas LA1, LA2, and LA3 may be included in the conductive layers 220 and 240 (see Figure 5 ) is blocked or reflected by the grid lines ML. For example, the grid lines ML may affect the light-emitting characteristics or light-emitting quality of the light-emitting areas LA1, LA2 and LA3 adjacent thereto.

[0178] When the plurality of light emitting areas LA1, LA2, and LA3 are spaced apart from each other, the display device according to the embodiment of the inventive concept may include a portion in which the separation distances GP1 and GP2 between the light emitting areas LA1, LA2, and LA3 and the grid lines ML are different from each other according to the arrangement form of the light emitting areas. The viewing angle range in which the grid lines ML affect the characteristics of light emitted from the light emitting areas LA1, LA2, and LA3 varies depending on the separation distances GP1 and GP2 between the light emitting areas and the grid lines.

[0179] refer to Fig. 8A and Figure 8B , the second grid line ML2 disposed between the light emitting areas LA3 spaced apart from each other by the first distance DT1 may be spaced apart from the adjacent third light emitting area LA3 by the first separation distance GP1. In addition, the second grid line ML2 disposed between the light emitting areas LA2 and LA1 spaced apart from each other by the second distance DT2 may be spaced apart from the adjacent second light emitting area LA2 by the second separation distance GP2.

[0180] The second grid line ML2 may block light emitted from the light emitting areas LA1, LA2, and LA3 adjacent thereto in a vertical direction (in a vertical direction). Fig. 8A In the embodiment of the present invention, the second grid line ML2 blocks light emitted in the direction parallel to the first direction DR1). Therefore, the light blocking property of the light emitted from the light emitting areas LA1, LA2 and LA3 blocked by the second grid line ML2 may vary depending on the separation distance between the second grid line ML2 and the light emitting areas LA1, LA2 and LA3 adjacent thereto. For example, in a portion where the second grid line ML2 is spaced apart from the adjacent second light emitting area LA2 by the second separation distance GP2 and in a portion where the second grid line ML2 is spaced apart from the adjacent third light emitting area LA3 by the first separation distance GP1, there may be a difference in the viewing angle of blocking light in the vertical direction (the direction parallel to the first direction DR1).

[0181] The display device according to an embodiment of the inventive concept may include a second protrusion portion BMP2 disposed in a portion where the light emitting area LA2 and the second grid line ML2 are spaced apart from each other by a second separation distance GP2, and a first protrusion portion BMP1 disposed in a portion where the light emitting area LA3 and the second grid line ML2 are spaced apart from each other by a first separation distance GP1 greater than the second separation distance GP2. Each of the first protrusion portion BMP1 and the second protrusion portion BMP2 may have a shape protruding from the second grid line ML2 toward an adjacent light emitting area. In a plan view, an area of ​​the first protrusion portion BMP1 may be greater than an area of ​​the second protrusion portion BMP2. In addition, a size BP_H of the first protrusion portion BMP1 in the first direction DR1 may be greater than a size of the second protrusion portion BMP2 in the first direction DR1. Since the first protrusion portion BMP1 has a size larger than that of the second protrusion portion BMP2, a difference between a separation distance between the first protrusion portion BMP1 and the third light emitting area LA3 and a separation distance between the second protrusion portion BMP2 and the second light emitting area LA2 may become smaller than a difference between the first separation distance GP1 and the second separation distance GP2. Therefore, by disposing the first protrusion BMP1 having a larger area in a plan view or a larger size in the first direction DR1 in a portion where the separation distance between the grid line ML and the light-emitting area LA1, LA2 or LA3 is relatively large, the difference in viewing angle characteristics caused by the difference in the separation distance between the light-emitting area and the grid line can be reduced.

[0182] In an embodiment of the present invention, the area of ​​the protrusion disposed in a portion where the separation distance between the grid line and the light-emitting region is relatively large may be larger than the area of ​​the protrusion disposed in a portion where the separation distance between the grid line and the light-emitting region is relatively small. In addition, the size in one direction of the protrusion disposed in a portion where the separation distance between the grid line and the light-emitting region is relatively large in one direction may be larger than the size in one direction of the protrusion disposed in a portion where the separation distance between the grid line and the light-emitting region is relatively small in one direction. For example, in a display device according to an embodiment of the present invention, by changing the size of the protrusion disposed between the light-emitting region and the grid line according to the separation distance between the light-emitting region and the grid line adjacent thereto, although the light-emitting regions are spaced at various distances from each other, the color difference depending on the viewing angle may be reduced, thereby exhibiting excellent display quality.

[0183] exist Fig. 8A and Figure 8BIn the embodiment of the inventive concept illustrated in , each of the first protrusion portion BMP1 and the second protrusion portion BMP2 is illustrated as having a circular shape in a plan view. However, this is an example and the first protrusion portion BMP1 and the second protrusion portion BMP2 may have different shapes, and the first protrusion portion BMP1 and the second protrusion portion BMP2 may have various shapes other than a circular shape. Each of the first protrusion portion BMP1 and the second protrusion portion BMP2 may have a circular, elliptical, quadrilateral or polygonal shape, or a combination of the above shapes.

[0184] In addition, in an embodiment of the present inventive concept, the shapes of the first protrusion portion BMP1 and the second protrusion portion BMP2 may be modified to various shapes corresponding to the shapes of the boundaries of the adjacent light emitting areas LA1, LA2, and LA3. For example, the edge of the protrusion portion BMP may have a shape corresponding to the shape of the boundaries of the light emitting areas LA1, LA2, and LA3, so that the separation distances between the adjacent light emitting areas LA1, LA2, and LA3 are substantially the same as each other. However, the embodiments of the present inventive concept are not necessarily limited thereto, and the shape of the protrusion portion BMP may be modified in various ways within the range of reducing the reflective visibility of the grid line ML and reducing the color difference depending on the viewing angle.

[0185] A size BP_H of the first protrusion portion BMP1 disposed between the light emitting regions LA3 spaced apart by the first distance DT1 in the first direction DR1 may be smaller than the first distance DT1. In addition, a width BP_W of the first protrusion portion BMP1 in the second direction DR2 may be smaller than a width LA3_W of the light emitting region LA3 in the second direction DR2.

[0186] Since one embodiment includes the first protrusion BMP1, the first protrusion BMP1 has a size BP_H in one direction that is smaller than the first distance DT1 that is the separation distance between the light-emitting areas LA3, and has a width BP_W that is smaller than the width LA3_W of the light-emitting area LA3, excellent display quality can be exhibited by adjusting the light extraction characteristics that depend on the viewing angle in a portion where the separation distance between the light-emitting areas is relatively large.

[0187] Fig. 9 is a cross-sectional view illustrating a portion of a display device according to an embodiment of the inventive concept. Fig. 9 Can be along Fig. 8A A cross-sectional view taken along line II-II'. Fig. 9 In FIG. 1 , some components of the display device DD are omitted, and only the stacked structure of the display panel 100 and the input sensor 200 is illustrated. Fig. 9 , the configuration of the circuit element layer 120 is illustrated as one layer. Figure 5The contents described can be equally applied to the Fig. 9 Contents related to configurations of the display panel 100 and the input sensor 200 in the display device according to the embodiment of the inventive concept are described.

[0188] Fig. 9 A cross section of a portion including the first, second, and third light emitting areas LA1, LA2, and LA3 is illustrated. The first, second, and third light emitting areas LA1, LA2, and LA3 may emit light of different wavelength ranges.

[0189] The display element layer 130 may include a plurality of light emitting elements LD1, LD2, and LD3 and a pixel defining film PDL. A light emitting opening PDL-OP may be defined in the pixel defining film PDL. The first light emitting element LD1 may include a first light emitting layer EL1, the second light emitting element LD2 may include a second light emitting layer EL2, and the third light emitting element LD3 may include a third light emitting layer EL3. The first to third light emitting layers EL1, EL2, and EL3 may include light emitting materials that emit light of different wavelength ranges. The first light emitting element LD1 may emit red light, the second light emitting element LD2 may emit green light, and the third light emitting element LD3 may emit blue light.

[0190] refer to Fig. 9 , the protrusions BMP1 and BMP2 may be disposed on the pixel defining film PDL. A size BP1_H in one direction of the first protrusion BMP1 disposed in an area where the first distance DT1 separating the light emitting areas is relatively large may be greater than a size BP2_H in one direction of the second protrusion BMP2 disposed in an area where the second distance DT2 separating the light emitting areas is relatively small. Therefore, as the difference between the distance in one direction between the edge of the first protrusion BMP1 and the third light emitting area LA3 and the distance in one direction between the edge of the second protrusion BMP2 and the second light emitting area LA2 decreases, the degree of blocking of light emitted from the light emitting areas LA1, LA2, and LA3 and directed to the protrusions BMP1 and BMP2 and the light blocking viewing angle may appear at similar levels.

[0191] In an embodiment of the inventive concept, the protruding portions BMP1 and BMP2 may be disposed on the same layer as the second conductive layer 240. However, the embodiments of the inventive concept are not necessarily limited thereto, and the protruding portions BMP1 and BMP2 may be disposed on the same layer as the first conductive layer 220, or may be selectively disposed on the first conductive layer 220 or the second conductive layer 240 according to the arrangement position on the display area.

[0192] Fig.10is a plan view illustrating a portion of a display device according to an embodiment of the inventive concept. Fig.10 The diagram shows a portion of a display device, which Figure 4B The display area corresponds to the Figure 7 Area AA corresponds to area AA-1.

[0193] The display device according to an embodiment of the inventive concept includes a plurality of light emitting areas LA1, LA2, and LA3, and may include first to third opening areas EOP1-1, EOP2-1, and EOP3-1 overlapping the light emitting areas LA1, LA2, and LA3. The first to third opening areas EOP1-1, EOP2-1, and EOP3-1 may be defined by first and second grid lines ML1-1 and ML2-1.

[0194] The first grid line ML1-1 may extend in a fourth direction DR4, and the second grid line ML2-1 may extend in a fifth direction DR5 crossing the fourth direction DR4. The fourth direction DR4 may be a direction extending between the first direction DR1 and the second direction DR2. The first to third opening areas EOP1-1, EOP2-1, and EOP3-1 may be defined by the first and second grid lines ML1-1 and ML2-1 crossing each other.

[0195] refer to Figure 4B and Fig.10 In an embodiment of the inventive concept, the first distance DT1-a between the second light emitting regions LA2 spaced apart from each other in the first direction DR1 may be greater than the second distance DT2-a between the third light emitting region LA3 and the first light emitting region LA1 spaced apart from each other in the first direction DR1. The first protrusion portion BMP1-1 may be disposed between the second light emitting regions LA2 spaced apart from each other by the first distance DT1-a, and the second protrusion portion BMP2-1 may be disposed between the third light emitting region LA3 and the first light emitting region LA1 spaced apart from each other by the second distance DT2-a. In a plan view, the area of ​​the first protrusion portion BMP1-1 may be greater than the area of ​​the second protrusion portion BMP2-1. In addition, the size of the first protrusion portion BMP1-1 in the first direction DR1 may be greater than the size of the second protrusion portion BMP2-1 in the first direction DR1.

[0196] exist Fig.10In the embodiment of the inventive concept illustrated in FIG. 1 , among the deviations of the separation distances between the light emitting regions LA1, LA2, and LA3, the deviation in the first direction DR1 may be greater than the deviation in the second direction DR2, the fourth direction DR4, or the fifth direction DR5. Therefore, the protrusions BMP1-1 and BMP2-1 may overlap the light emitting regions LA1, LA2, and LA3 in the first direction DR1.

[0197] However, even in this case, when viewed on a plane perpendicular to the third direction DR3, the protruding portions BMP1-1 and BMP2-1 do not overlap with the light emitting areas LA1, LA2, and LA3 adjacent thereto. For example, the size of the first protruding portion BMP1-1 disposed between two second light emitting areas LA2 adjacent to each other in the first direction DR1 in the second direction DR2 may be smaller than the separation distance between the first light emitting area LA1 and the third light emitting area LA3 adjacent to each other in the second direction DR2. In addition, the size of the second protruding portion BMP2-1 disposed between two second light emitting areas LA2 adjacent to each other in the second direction DR2 in the first direction DR1 may be smaller than the separation distance between the first light emitting area LA1 and the third light emitting area LA3 adjacent to each other in the first direction DR1.

[0198] Therefore, since the first protrusion portion BMP1-1 having a relatively large area between two second light-emitting areas LA2 adjacent to each other in the first direction DR1 where the deviation of the separation distance between the light-emitting areas LA1, LA2 and LA3 is large does not overlap with the light-emitting areas LA1, LA2 and LA3 in the third direction DR3, and the second protrusion portion BMP2-1 having a relatively small area compared with the first protrusion portion BMP1-1 between the first light-emitting area LA1 and the third light-emitting area LA3 adjacent to each other in the first direction DR1 does not overlap with the light-emitting areas LA1, LA2 and LA3 in the third direction DR3, while preventing the emitted light from being blocked, by adjusting the light extraction characteristics depending on the viewing angle, excellent display quality can be exhibited. In an embodiment of the present inventive concept, each of the first protrusion portion BMP1-1 and the second protrusion portion BMP2-1 may be located in a portion where the first grid line ML1-1 and the second grid line ML2-1 intersect each other. An embodiment may further include a cutting portion CTP defined in the grid lines ML1-1 and ML2-1.

[0199] The protrusions BMP1-1 and BMP2-1 may have a shape protruding inside the opening areas EOP1-1, EOP2-1, and EOP3-1 defined by the grid lines ML1-1 and ML2-1. The size of the first protrusion BMP1-1 in the first direction DR1 may be greater than the size of the second protrusion BMP2-1 in the first direction DR1, and thus, the light emitting area LA2 and the conductive layer 240 (see FIG. 2 ) are spaced apart from each other when compared to the distance before the first protrusion BMP1-1 is introduced. Figure 5 ) may be reduced due to the first protrusion portion BMP1-1. In an embodiment of the inventive concept, as the difference between the separation distance between the first protrusion portion BMP1-1 and the second light emitting region LA2 and the separation distance between the second protrusion portion BMP2-1 and the first light emitting region LA1 or the third light emitting region LA3 is reduced, the conductive layer 240 (see Figure 5 ) can appear at a similar level in the entire light-emitting area. For example, a display device according to an embodiment of the inventive concept may include an input sensor in which protrusions having different sizes are arranged according to the difference in separation distances between light-emitting areas of the display panel. In an embodiment of the inventive concept, since a protrusion having a relatively large size is arranged between light-emitting areas having a relatively large separation distance therebetween, the difference in separation distance in one direction between the conductive layer and the light-emitting area can be adjusted to a similar level in the entire light-emitting area, thereby reducing the deviation of chromatic aberration depending on the viewing angle and exhibiting excellent display quality.

[0200] Fig. 8A and Fig.10 The diagrams show Figure 4A and Figure 4B An embodiment of a display device having a configuration of a display area, and reference FIG. 8A to FIG. 10 The arrangement of the protruding portions described above is not necessarily limited to the illustrated arrangement but may vary depending on the arrangement of the light emitting areas.

Figure 5 ) is provided with a first conductive layer 220 (see Figure 5 ) is part of the same layer as the layer of Fig.13A It may be the first conductive layer 220 corresponding to the lower conductive layer CL-L (see Figure 5 ) parts of the same layer.

In embodiments of the present inventive concept, the length of the lower grid line ML_L in the second direction DR2 may be greater than or equal to a distance of the cutting portion CTP defined in the upper conductive layer CL-T in the second direction DR2, which will be described later.

Figure 5 ) is provided with a second conductive layer 240 (see Figure 5) is part of the same layer as the layer of Fig. 13B It may be a second conductive layer 240 corresponding to the upper conductive layer CL-T (see Figure 5 ) of the same layer.

A plurality of cutting portions CTP may be defined in Fig. 13B The upper conductive layer CL-T may be stacked on top of the lower conductive layer CL-L.

[0220] Fig. 13C is a plan view illustrating a partial area AA-2 of a display device according to an embodiment of the inventive concept, which includes a lower conductive layer CL-L and an upper conductive layer CL-T disposed on the lower conductive layer CL-L.

[0221] When the lower conductive layer CL-L and the upper conductive layer CL-T are stacked, the third protrusion portion BMP2-L may overlap the cutting portion CTP. In addition, a size of the third protrusion portion BMP2-L in the first direction DR1 may be smaller than a size of the first protrusion portion BMP1 in the first direction DR1.

Therefore, the display device according to the embodiment of the inventive concept can reduce the visibility problem in which a specific shape of a boundary cutting portion or a grid line formed at a specific position in a sensing pattern of an input sensor is visible, and by disposing a first protrusion having a relatively large size in a portion where the separation distance between the light emitting areas is large, the deviation of the color difference at each viewing angle can be reduced depending on the difference in the separation distance between the light emitting areas. Therefore, the display device according to the embodiment of the inventive concept can have better visibility and exhibit excellent viewing angle characteristics while reducing the deviation of the color difference over the entire display area.

[0223] Table 1 below and FIG. 14A to FIG. 14C Results of comparing and evaluating color differences for each viewing angle according to a comparative example and the example are shown. Fig.14A Corresponding to the results of the comparative example in Table 1, and Fig. 14Band Fig. 14C They correspond to the results of Example 1 and Example 2 in Table 1 respectively.

[0224] In Table 1 and FIG. 14A to FIG. 14C The protrusion used in the evaluation has a square shape in a plan view. The comparative example corresponds to a case where both the first protrusion and the second protrusion have the same size of 1 μm×1 μm. Unlike the comparative example, Example 1 corresponds to a case where the size of the first protrusion is 2 μm×2 μm. Unlike the comparative example, Example 2 corresponds to a case where the size of the first protrusion is 4 μm×4 μm. For example, compared with the comparative example, each of Example 1 and Example 2 is different in that the size of the first protrusion becomes larger.

[0225] In Table 1 and FIG. 14A to FIG. 14C In the evaluation results, the horizontal viewing angle is the same as that in the case of Fig. 8A The viewing angle in the direction of the second direction DR2 illustrated in the figure corresponds to the viewing angle in the direction of the second direction DR2, and the vertical viewing angle corresponds to the viewing angle in the direction parallel to the Fig. 8A It corresponds to the viewing angle in the first direction DR1 illustrated in FIG.

[0226] FIG. 14A to FIG. 14C Color coordinates of white light of the comparative example, Example 1, and Example 2 according to horizontal and vertical viewing angles are illustrated. FIG. 14A to FIG. 14C The portion marked with a solid line in FIG. 1 corresponds to a portion where the color difference (Δu'v') is less than 0.01.

[0227] [Table 1]

[0228]

[0229] Reference depends on Table 1 and FIG. 14A to FIG. 14C , it can be seen that as the size of the first protruding portion increases, the difference in the y color coordinate according to the viewing angle in the vertical direction decreases. In addition, it can be seen that although the viewing angle changes as the size of the first protruding portion increases, the y color coordinate shows a value similar to the y color coordinate in the 0° direction (i.e., the front direction).

[0230] In addition, the horizontal color coordinates look similar regardless of the size of the first protrusion. This is believed to be because when the light emitting area is as Fig. 8A For example, it can be seen that the arrangement of the protruding portion has a greater influence on the viewing angle characteristics in the direction where the difference in separation distance between the light emitting areas is large.

[0231] In addition, from Table 1 and FIG. 14A to FIG. 14CFrom the results, it can be seen that as the size of the first protrusion portion provided in the portion where the separation distance between the light emitting areas is relatively large increases, the chromatic aberration decreases in the front direction and in the direction in which the viewing angle increases.

[0232] Since the display device according to the embodiment of the inventive concept includes the protrusion having different sizes depending on the separation distance between the light emitting areas on the conductive layer of the input sensor, the difference in viewing angle characteristics depending on the difference in the separation distance between the light emitting areas can be reduced. In addition, in the display device according to the embodiment of the inventive concept, since the light emitting area and the protrusion overlap each other in a direction in which the difference in the separation distance between the light emitting areas is large, the color difference caused by the separation distance between the light emitting areas can be reduced, thereby exhibiting excellent color characteristics and display quality.

[0233] The display device according to an embodiment of the inventive concept may exhibit excellent display quality by changing the size of a protrusion included in a sensing pattern of an input sensor according to a separation distance between light emitting areas.

[0234] Furthermore, the display device according to an embodiment of the inventive concept may reduce the color difference depending on the viewing angle according to the arrangement of the light emitting areas by differentially applying protrusions of different sizes depending on the separation distance between the light emitting areas.

[0235] Although the above has been described with reference to the embodiments of the inventive concept, those skilled in the art or ordinary technicians in the field will understand that various modifications and changes can be made to the inventive concept without departing from the spirit and technical scope of the inventive concept.

[0236] Therefore, the technical scope of the inventive concept is not necessarily limited to the contents described in the detailed description of the specification.
