Abstract
Provided is a display device including a plurality of pixels and a touch sensor overlapping with the plurality of pixels, the touch sensor. The touch sensor possesses: a first wiring arranged in a first direction and including a plurality of first electrodes; and a second wiring arranged in a second direction intersecting the first direction and including a plurality of second electrodes. Each of the first electrodes and each of the second electrodes vary in width continuously or stepwise in the first direction and the second direction, respectively, and satisfy a certain relationship with respect to an area and a total length of sides thereof.
