Abstract

A display device includes a first display area and a second display area located on opposite sides of a display area. The display device includes first through third sub-pixels. The first through third sub-pixels are disposed in the first and second display areas. The first and second sub-pixels are arranged in a first column adjacent to a first boundary, and the third sub-pixels are arranged in a second column. The second and first sub-pixels are arranged in a third column adjacent to a second boundary, and the third sub-pixels are arranged in a fourth column. The third sub-pixels are arranged in a first column and a second column of the first sub-area. The first and second sub-pixels are arranged in a first column and a second column of the third sub-area. The first to third sub-pixels are not disposed in the second column of the first and third sub-areas.

First claim

A display device including a display area, a first display area located in one side of the display area and including a first sub-area and a second sub-area, and a second display area located in an opposite side of the display area and including a third sub-area and a fourth sub-area, the display device comprising:
a substrate; and a plurality of first sub-pixels, second sub-pixels, and third sub-pixels disposed in the display area, the first display area, and the second display area on the substrate, wherein the plurality of first and second sub-pixels are repeatedly arranged in a first column of the display area that is adjacent to a first boundary between the display area and the first sub-area, and the plurality of third sub-pixels are arranged in a second column of the display area, the plurality of second and first sub-pixels are repeatedly arranged in a third column of the display area that is adjacent to a second boundary between the display area and the third sub-area, and the plurality of third sub-pixels are arranged in a fourth column of the display area, the plurality of third sub-pixels disposed closest to the first boundary in the first display area constitute a first-first sub-pixel set, the plurality of third sub-pixels disposed closest to the second boundary in the second display area constitute a second-second sub-pixel set, and a distance between the first-first sub-pixel set and the second column of the display area is substantially equal to a distance between the second-second sub-pixel set and the fourth column of the display area.

2 . The display device of claim 1 , wherein
a first-second sub-pixel set spaced apart from the first-first sub-pixel set in a direction from the display area to the first display area includes the plurality of second and first sub-pixels, a first-third sub-pixel set spaced apart from the first-second sub-pixel set in the direction from the display area to the first display area includes the plurality of third sub-pixels, and a first-fourth sub-pixel set spaced apart from the first-third sub-pixel set in the direction from the display area to the first display area includes the plurality of first and second sub-pixels.

3 . The display device of claim 2 , wherein sizes of the plurality of first to third sub-pixels disposed in the first and second display areas are greater than sizes of the plurality of first to third sub-pixels disposed in the display area, respectively.

4 . The display device of claim 2 , wherein a distance between the first-first sub-pixel set and the first-second sub-pixel set is smaller than a distance between the first-second sub-pixel set and the first-third sub-pixel set.

5 . The display device of claim 4 , wherein a distance between the first-third sub-pixel set and the first-fourth sub-pixel set is smaller than the distance between the first-second sub-pixel set and the first-third sub-pixel set.

6 . The display device of claim 5 , wherein a distance between the first-first sub-pixel set and the first-third sub-pixel set is substantially equal to a distance between the first-second sub-pixel set and the first-fourth sub-pixel set.

7 . The display device of claim 2 , wherein a distance between the first-first sub-pixel set and the first-second sub-pixel set is substantially equal to a distance between the first-second sub-pixel set and the first-third sub-pixel set.

8 . The display device of claim 7 , wherein a distance between the first-third sub-pixel set and the first-fourth sub-pixel set is substantially equal to the distance between the first-second sub-pixel set and the first-third sub-pixel set.

9 . The display device of claim 8 , wherein a distance between the first-first sub-pixel set and the first-third sub-pixel set is substantially equal to a distance between the first-second sub-pixel set and the first-fourth sub-pixel set.

10 . The display device of claim 1 , wherein
a second-first sub-pixel set spaced apart from the second-second sub-pixel set in a direction from the second display area to the display area includes the plurality of first and second sub-pixels, a second-third sub-pixel set spaced apart from the second-second sub-pixel set in a direction from the display area to the second display area includes the plurality of second and first sub-pixels, and a second-fourth sub-pixel set spaced apart from the second-third sub-pixel set in the direction from the display area to the second display area includes the plurality of third sub-pixels.

11 . The display device of claim 10 , wherein sizes of the plurality of first to third sub-pixels disposed in the first and second display areas are greater than sizes of the plurality of first to third sub-pixels disposed in the display area, respectively.

12 . The display device of claim 10 , wherein a distance between the second-first sub-pixel set and the second-second sub-pixel set is smaller than a distance between the second-second sub-pixel set and the second-third sub-pixel set.

13 . The display device of claim 12 , wherein a distance between the second-third sub-pixel set and the second-fourth sub-pixel set is smaller than the distance between the second-second sub-pixel set and the second-third sub-pixel set.

14 . The display device of claim 13 , wherein a distance between the second-first sub-pixel set and the second-third sub-pixel set is substantially equal to a distance between the second-second sub-pixel set and the second-fourth sub-pixel set.

15 . The display device of claim 10 , wherein a distance between the second-first sub-pixel set and the second-second sub-pixel set is substantially equal to a distance between the second-second sub-pixel set and the second-third sub-pixel set.

16 . The display device of claim 15 , wherein a distance between the second-third sub-pixel set and the second-fourth sub-pixel set is substantially equal to the distance between the second-second sub-pixel set and the second-third sub-pixel set.
