1. A display unit with touch detection function comprising:

  • 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,wherein 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.
