Abstract
A touch panel-equipped display device includes at least: a display control unit to supply a scan signal and a data signal to a display control element; and a touch position detection control unit to supply a drive signal to a drive electrode, and to detect a position detection signal from a detection electrode to detect a touch position. The display control unit supplies the data signal sequentially to a plurality of display control elements connected respectively to a plurality of pixel electrodes constituting one display pixel. The touch position detection control unit starts supplying the drive signal, in a period that is within a scan write period during which the scan signal is supplied to the display control element and is other than a period during which the data signal is supplied to the display control element corresponding to a color highest in luminosity of a plurality of colors.
