Abstract
The touch sensor includes a touch detection area with at least a part of a curved area having a curved edge. In the touch detection area, a plurality of first electrodes and second electrodes disposed side by side in a first direction and in a second direction are disposed. A plurality of first electrodes disposed side by side in the first direction are connected to each other. A plurality of second electrodes disposed side by side in the second direction are connected to each other. In the curved area, distances between the plurality of first electrodes and the second electrodes in the first direction gradually change in the second direction.

A touch sensor comprising:
- a touch detection area having a first area and a curved area having a curved edge, the curved area adjacent to the first area, wherein
- in the touch detection area, a plurality of first electrodes and second electrodes are disposed,
- the plurality of first electrodes are disposed side by side in a first direction and connected to each other by a first connection line which is at a different layer as the plurality of first electrodes and the second electrodes,
- the plurality of second electrodes are disposed side by side in a second direction and connected to each other,
- in the curved area, distances between the plurality of first electrodes and the second electrodes in the first direction gradually change in the second direction, and
- an extending direction of the first connection line in the curved area is different from the extending direction of the first connection line in the first area.
A display device comprising:
- a display unit in which a light emitting element and a plurality of pixels having transistors are disposed in a matrix shape;
- a touch sensor having a plurality of first electrodes and second electrodes disposed side by side in a first direction and in a second direction, and the display unit being overlapped in a plan view;
- a first area;
- and
- a curved area having a curved edge at least at a part thereof, the curved area adjacent to the first area, wherein
- the plurality of first electrodes disposed side by side in the first direction are connected to each other by a first connection line which is at a different layer as the plurality of first electrodes and the second electrodes,
- the plurality of second electrodes disposed side by side in the second direction are connected to each other,
- in the curved area, distances between the plurality of first electrodes and the second electrodes in the first direction gradually change in the second direction, and
- an extending direction of the first connection line in the curved area is different from the extending direction of the first connection line in the first area.
