Abstract
The touch sensor device and the display device include: a panel unit having a touch detection area in which a plurality of drive electrodes extend in an X-direction, a plurality of detection electrodes extend in a Y-direction, and a plurality of detection units each composed of a pair of the drive electrode and the detection electrode are formed in a matrix pattern; the drive electrodes each having a width forming two detection units in the Y-direction; and regions each formed by the intersection between one drive electrode and first to fourth detection electrodes. In this region, detection regions having a first sensitivity in which first to fourth detection units are provided and non-detection regions having a second sensitivity are alternately disposed. For example, the detection electrodes have different shapes between the detection region and the non-detection region.
