A display device with a touch panel, wherein the effect made on an image display by the supply of a drive signal to a drive electrode in order to detect a touch position is suppressed. The display device with a touch panel is provided with at least a display control unit for supplying a scanning signal and a data signal to a display control element and performing display control, and a touch position detection control unit for supplying a drive signal to a drive electrode and detecting a position detection signal outputted from a detection electrode, thereby detecting a touch position. When the data signal is supplied to the display control element, the display control unit successively supplies the data signal to a plurality of display control elements connected to each of a plurality of pixel electrodes constituting part of one display pixel. The touch position detection control unit starts supplying the drive signal to the drive electrode during a scanning write period in which the scanning signal is supplied to the display control elements, the scanning drive period being a period other than the period during which the data signal is supplied to a display control element that corresponds to a color that has the highest luminous sensitivity among a plurality of colors.
