Abstract

A display device with a touch sensor includes: plural display pixel electrodes; a common electrode arranged opposite to the display pixel electrodes; a display function layer having an image display function; a display control circuit performing image display control so as to fulfill the display function of the display function layer by applying a voltage for display between the display pixel electrodes and the common electrode based on an image signal; and a touch detection electrode provided opposite to the common electrode and forming capacitance between the touch detection electrode and the common electrode, wherein a drive voltage for display applied to the common electrode by the display control circuit is used as a drive signal for the touch sensor, and a gate potential of TFT circuits included in the display pixel electrodes is increased during a period when the drive signal for the touch sensor is applied.
