Abstract

According to one embodiment, a display device includes a display area with pixels, and a detection electrode which includes first conductive lines overlapping the display area. Each of the pixels includes a first subpixel, a second subpixel adjacent to the first subpixel in a first direction, a third subpixel adjacent to the first subpixel in a second direction, and a fourth subpixel adjacent to the third subpixel in the first direction and to the second subpixel in the second direction. The pixels are arranged in the first direction with a first pitch, and the first conductive lines are arranged in the first direction with a second pitch which falls within a range of 2.2 times the first pitch or more and 3.2 times the first pitch or less.

Claims (37)

1. A display device comprising:

a display area which includes a plurality of pixels; and

a detection electrode which includes a plurality of first conductive lines overlapping the display area, wherein

each of the pixels includes a first subpixel, a second subpixel adjacent to the first subpixel in a first direction, a third subpixel adjacent to the first subpixel in a second direction crossing the first direction, and a fourth subpixel adjacent to the third subpixel in the first direction and adjacent to the second subpixel in the second direction,

the pixels are arranged in the first direction with a first pitch,

the first conductive lines are arranged in the first direction with a second pitch which falls within a range of 2.2 times the first pitch or more and 3.2 times the first pitch or less, and

luminance of a display color of each of the second subpixel and the third subpixel is higher than luminance of a display color of each of the first subpixel and the fourth subpixel.

2. The display device of claim 1 , further comprising a detection module which detects an object in proximity to the display area based on a signal from the detection electrode.

3. The display device of claim 1 , wherein the second pitch falls within a range of 2.6 times the first pitch or more and 2.8 times the first pitch or less.

4. The display device of claim 1 , wherein each of the first conductive lines forms an angle of between 10° and 31° inclusive with respect to the second direction.

5. The display device of claim 4 , wherein each of the first conductive lines forms an angle of between 13° and 27° inclusive with respect to the second direction.

6. The display device of claim 1 , wherein a display color of each of the second subpixel and the third subpixel is green or white.

7. The display device of claim 1 , wherein

a display color of each of the first subpixel and the fourth subpixel is red or blue, and

a display color of each of the second subpixel and the third subpixel is green.

8. The display device of claim 1 , wherein

the detection electrode includes a plurality of second conductive lines which overlap the display area, extend parallel to each other, and cross the first conductive lines, and

the second conductive lines are arranged in the first direction with a third pitch which falls within a range of 2.2 times the first pitch or more and 3.2 times the first pitch or less.

9. The display device of claim 8 , wherein each of the second conductive lines forms an angle of between 10° and 31° inclusive with respect to the second direction.

10. The display device of claim 1 , further comprising:

a pixel electrode provided in each of the first subpixel, the second subpixel, the third subpixel, and the fourth subpixel; and

a driving electrode which produces an electrical field for image display between the driving electrode and the pixel electrode, wherein

the detection electrode produces capacitance between the detection electrode and the driving electrode and outputs a signal according to a change in the capacitance.

11. The display device of claim 1 , wherein the pixels are arranged in the first direction and in the second direction with the first pitch.

12. The display device of claim 1 , wherein the first subpixel, the second subpixel, the third subpixel, and the fourth subpixel have the same area as each other.

13. A display device comprising:

a display area which including a plurality of pixels arranged in a matrix, wherein

each of the pixels includes a first subpixel, a second subpixel adjacent to the first subpixel in a first direction, a third subpixel adjacent to the first subpixel in a second direction crossing the first direction, and a fourth subpixel adjacent to the third subpixel in the first direction and adjacent to the second subpixel in the second direction, and

luminance of a display color of each of the second subpixel and the third subpixel is higher than luminance of a display color of each of the first subpixel and the fourth subpixel.

14. The display device of claim 13 , wherein

a display color of each of the first subpixel and the fourth subpixel is red or blue, and

a display color of each of the second subpixel and the third subpixel is green or white.

15. The display device of claim 13 , wherein

a display color of each of the first subpixel and the fourth subpixel is red or blue, and

a display color of each of the second subpixel and the third subpixel is green.

16. The display device of claim 13 , wherein the pixels are arranged in the first direction and in the second direction with a first pitch.

17. The display device of claim 13 , wherein the first subpixel, the second subpixel, the third subpixel, and the fourth subpixel have the same area as each other.
