Abstract
A display device includes: a plurality of drive electrodes; a plurality of detection electrodes intersecting the plurality of drive electrodes; and a scan driving unit performing a first scan drive and a second scan drive. The first scan drive allows a display drive signal for driving the display elements to be applied to each of the plurality of common drive electrodes, and the second scan drive allows a touch detection drive signal for detecting an external proximity object to be applied to each of the plurality of common drive electrodes.
