Abstract
A display device including a substrate, a plurality of pixel electrodes arranged in a form of a matrix in a plane parallel with the substrate, a display functional layer exerting an image display function on a basis of an image signal supplied to the plurality of pixel electrodes, a driving electrode opposed to the plurality of pixel electrodes, and a plurality of detecting electrodes arranged in a form of a plane opposed to the driving electrode, separated and arranged at a pitch of a natural number multiple of an arrangement pitch of the pixel electrodes in one direction in the arrangement plane, and each capacitively coupled with the driving electrode.
Claims5
A display device having a display layer, the display layer comprising:
- a plurality of pixel electrodes;
- a scanning line extending in a first direction;
- a signal line extending in a second direction crossing the first direction;
- a plurality of common electrodes facing the pixel electrodes with a gap between the common electrodes in the second direction;
- and
- an insulating layer between the common electrodes and a layer including the scanning line in a first layer and the signal line in a second layer that is different from the first layer,
- wherein
- the scanning line overlaps the gap,
- each of the pixel electrodes partially overlaps the signal line, and
- each of the common electrodes partially overlaps the signal line.
