Abstract

A display device includes: a substrate including a display area including a plurality of first pixels and a sensor area including a plurality of second pixels and a plurality of transmission portions, a plurality of first counter electrodes disposed corresponding to the plurality of first pixels, respectively, a plurality of second counter electrodes disposed corresponding to the plurality of second pixels, respectively, and a spacer disposed to overlap at least a portion of a boundary region between a transmission portion of the plurality of transmission portions and a second counter electrode of the plurality of second counter electrodes, which are adjacent to each other.

First claim

What is claimed is:

1. A display device comprising:
a substrate including:
a display area including a plurality of first pixels; and
a sensor area including a plurality of second pixels and a plurality of transmission portions;

a plurality of first counter electrodes disposed corresponding to the plurality of first pixels, respectively;
a plurality of second counter electrodes disposed corresponding to the plurality of second pixels, respectively; and
a spacer disposed to overlap at least a portion of a boundary region between a transmission portion of the plurality of transmission portions and a second counter electrode of the plurality of second counter electrodes, which are adjacent to each other.

2. The display device of claim 1 , wherein the spacer includes at least one organic material selected from polyimide, polyamide and acrylic resin and phenol resin.

3. The display device of claim 1 , further comprising:
a component disposed below the transmission portion,
wherein the component includes a sensor which senses an infrared light, a visible light or a sound.

4. The display device of claim 1 , wherein an area of the plurality of transmission portions is greater than an area of an emission region of the plurality of second pixel.

5. The display device of claim 1 , wherein the number of the plurality of second pixels per unit area is less than the number of the plurality of first pixels per unit area.

6. The display device of claim 1 , wherein the plurality of first counter electrodes and the plurality of second counter electrodes are electrically connected to each other.

7. The display device of claim 1 , wherein
each of the plurality of first counter electrodes has a first rectangular shape having a first width in a first direction and a first height in a second direction crossing the first direction, and
each of the plurality of second counter electrodes has a second rectangular shape with protrusions protruding in the first direction from four vertices of the second rectangular shape, and
the second rectangular shape has a second width in the first direction and a second height in the second direction.

8. The display device of claim 7 , wherein
the first width is greater than the second width, and
the first height is less than the second height.

9. The display device of claim 8 , wherein each of the plurality of transmission portions has a third rectangular shape surrounded by the plurality of second counter electrodes.

10. The display device of claim 9 , wherein the third rectangular shape has a third width in the first direction and has a third height in the second direction.

11. The display device of claim 10 , wherein the third width is greater than the first width and the second width.

12. The display device of claim 9 , wherein
the spacer has a predetermined width, and
the spacer is disposed to at least partially overlap a boundary region between the transmission portion and the protrusions of the second counter electrode in the first direction and a boundary region between the transmission portion and the second rectangular shape of the second counter electrode in the second direction.

13. The display device of claim 9 , wherein
the spacer has a predetermined width, and
the spacer is disposed along a perimeter of the third rectangular shape.

14. The display device of claim 8 , wherein each of the plurality of second counter electrodes further include a curved portion at an intersection of a region of the protrusion extending in the first direction and a region of the second rectangular shape extending in the second direction.

15. The display device of claim 14 , wherein
the spacer has a triangular shape, and
the spacer is disposed to at least partially overlap the curved portion.

16. The display device of claim 7 , wherein
adjacent first counter electrodes in the first direction, among the plurality of first counter electrodes, overlap each other at an edge of the first rectangular shape, and
adjacent second counter electrodes along an edge of the transmission portion, among the plurality of second counter electrodes, overlap each other at the protrusion.

17. The display device of claim 7 , wherein adjacent first counter electrodes in the second direction, among the plurality of first counter electrodes, are spaced apart from each other.

18. The display device of claim 7 , wherein the substrate further includes a non-display area disposed to surround the display area and the sensor area.

19. The display device of claim 18 , wherein a power supply wiring extending in the second direction is disposed on the non-display area of the substrate.

20. The display device of claim 19 , wherein the plurality of first counter electrodes spaced apart from each other in the second direction are electrically connected to each other through the power supply wiring.
