Abstract:
According to an aspect, a touch detection device has a detection surface for detecting a position of an external proximity object which is in contact therewith or in proximity thereto. The touch detection device includes: a drive electrode layer that has a plurality of drive electrodes; a plurality of touch detection electrodes that face the drive electrodes; a drive electrode driver for applying a driving signal to the drive electrodes; and a plurality of wirings for electrically coupling the plurality of drive electrodes with the drive circuit. In the drive electrode layer, a specific drive electrode coupled via the wiring with a longest distance has an overlapped area smaller than an average of the overlapped areas of the other drive electrodes. The overlapped area is an area that is overlapped with the wiring.
