摘要：
A display device with a touch detection function includes a plurality of common drive electrodes arranged side by side to extend in one direction, a display element performing display, based on a pixel signal and a display drive signal, a touch detection element of electrostatic capacitance type detecting an external proximity object based on a touch detection drive signal with an amplitude larger than that of the display drive signal, and a scan drive section performing first scan drive and second scan drive, the first scan drive allowing the plurality of common drive electrodes to be sequentially supplied with the display drive signal in a time-divisional manner, and the second scan drive allowing the plurality of common drive electrodes to be sequentially supplied with the touch detection drive signal in a time-divisional manner.
