Abstract: An object of the present invention is to provide a technique for providing a detection function of detecting that an external approaching object approaches a sensor region of a touch sensor, without increasing an area of the touch sensor and making a circuit complex. According to an aspect, a display device includes a first detection electrode that detects a position of an external approaching object within a detection surface, and plural second detection electrodes that detect that the external approaching object approaches the detection surface. The second detection electrodes extend in a second direction and are arranged in a first direction intersecting the second direction. The second detection electrodes overlap the first detection electrode in a plan view.
