    摘要： A display unit with touch detection function includes a plurality of pixel signal lines each transmitting a pixel signal for display; a pixel signal line drive section applying the pixel signal to each of the pixel signal lines; display elements each performing display based on the pixel signal; touch detection electrodes each outputting a detection signal based on a change in capacitance occurring due to an external proximity object; and a touch detection section detecting, in a touch detection period, a touch event based on the detection signal, the touch detection period being different from a display period for the display elements to perform display operation. The pixel signal line drive section maintains a voltage of each of the pixel signal lines at a certain level during the touch detection period.
