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.

Claims (31)

1. A display device comprising a display layer, the display layer including:

a plurality of pixel electrodes;

a scanning line extending in a first direction;

a signal line extending in the second direction crossing the first direction;

a plurality of detection electrodes; and

an insulating layer between the detection electrodes and lines including the scanning line and the signal line,

wherein,

one of the detection electrodes includes one or more inner slits,

each of the one or more inner slits has ends inside the one of the detection electrodes such that each of the one or more inner slits is contained within the one of the detection electrodes, and

the one or more inner slits in the one of the detection electrodes overlap the scanning line, the signal line, or both the scanning line and the signal line.

2. The display device according to claim 1 , wherein:

a plurality of inter slits are disposed between adjacent detection electrodes,

the scanning line is one of a plurality of scanning lines,

the signal line is one of a plurality of signal lines, and

the inter slits overlap the scanning lines, the signal lines, or both the scanning lines and the signal lines.

3. The display device according to claim 2 , further comprising a group of floating electrodes arranged between the detection electrodes, wherein, the group of floating electrodes are divided by the inter slits.

4. The display device according to claim 3 , wherein:

the detection electrodes are arranged at a pitch of a natural multiple number of an arrangement pitch of the pixel electrodes in a row direction and/or a column direction in an arrangement plane, and

the floating electrodes are arranged at a pitch of the arrangement pitch of the pixel electrodes in the row direction and/or the column direction, in the arrangement plane.

5. The display device according to claim 3 , wherein, the inter slits are connected to each other.

6. The display device according to claim 3 , wherein, the inter slits and the one or more inner slits overlap pixels of a same color.

7. The display device according to claim 2 , wherein, the inter slits are located between the pixel electrodes.

8. The display device according to claim 7 , wherein, the one or more inner slits of the detection electrodes are located between the pixel electrodes.

9. The display device according to claim 2 , wherein, the inter slits are connected to each other.

10. The display device according to claim 2 , wherein, the inter slits and the one or more inner slits overlap pixels of a same color.

11. The display device c according to claim 1 , wherein:

the one or more inner slits overlapping the scanning line extend in the first direction, and

the one or more inner slits overlapping the signal line extend in the second direction.

12. The display device according to claim 1 , further comprising a detection circuit coupled to the detection electrodes.

13. The display device according to claim 1 , wherein, the detection electrodes are arranged at a pitch of a natural multiple number of an arrangement pitch of the pixel electrodes in a row direction and/or a column direction, in an arrangement plane.

14. The display device according to claim 1 , wherein, the one or more inner slits of the detection electrodes are located between the pixel electrodes.
