Abstract

A display device includes a plurality of first sub-pixels configured to display red, a plurality of second sub-pixels configured to display green, a plurality of third sub-pixels configured to display blue, and a plurality of fourth sub-pixels configured to display white, a first signal line coupled to the first sub-pixels, a second signal line coupled to the second sub-pixels, and a third signal line coupled to the third sub-pixels and the fourth sub-pixels, a plurality of detection electrodes arrayed in a matrix (row-column configuration) and each provided overlapping the first sub-pixels, the second sub-pixels, the third sub-pixels, and the fourth sub-pixels, and a plurality of signal supply wires coupled to the respective detection electrodes. The signal supply wires are each provided overlapping at least one of the first signal line and the second signal line and not overlapping the third signal line.

Claims (35)

1. A display device comprising:

a first insulating film;

a second insulating film on the first insulating film; detection electrodes arrayed in a matrix in a display region and provided on the second insulating film; and

touch detection lines provided between the first insulating film and the second insulating film,

wherein

the detection electrodes include a first detection electrode,

the touch detection lines include a first touch detection line,

the second insulating film includes a first hole and a second hole,

the first detection electrode is overlapped by the first hole and the second hole,

the first detection electrode is connected to the first touch detection line via the first hole, and

the first detection electrode is in contact with the first insulating film in the second hole.

2. The display device of claim 1 , wherein none of touch detection lines overlap the second hole.

3. The display device of claim 1 , further comprising a red video signal line, a green video signal line, and a blue video signal line, wherein

the first hole is located near the red video signal line or the green video signal line, and is not located near the blue video signal line, and

the second hole is located near the blue video signal line and is not located near the red video signal line or the green video signal line.

4. The display device of claim 1 , further comprising a red video signal line, a green video signal line, and a blue video signal line, wherein

the first hole overlaps the red video signal line or the green video signal line, and does not overlap the blue video signal line, and

the second hole overlaps the blue video signal line and does not overlap the red video signal line or the green video signal line.

5. The display device of claim 1 , further comprising metal lines between the first insulating film and the second insulating film,

wherein

the first touch detection line extends in a first direction,

the metal lines are aligned in the first direction with a gap therebetween and overlap the first detection electrode, and

the second hole is located between two of the metal lines adjacent to each other in the first direction.

6. The display device of claim 5 , wherein none of the metal lines overlap the second hole.

7. The display device of claim 5 , wherein

the metal lines are a floating state, and

the first detection electrode is not connected to the metal lines.

8. The display device of claim 7 , further comprising a blue video signal line, wherein

the second hole and metal lines are located near the blue video signal line.

9. The display device of claim 8 , further comprising a red video signal line and a green video signal line, wherein

the second hole and metal lines are located apart from the red video signal line and the green video signal line.

10. The display device of claim 7 , further comprising a blue video signal line, wherein

the blue video signal line is overlapped by the second hole and metal lines.

11. The display device of claim 10 , further comprising a red video signal line and a green video signal line, wherein

the second hole and metal lines overlap none of the red video signal line and a green video signal line.
