1. A display device with a touch sensor comprising:

  • a plurality of pixel electrodes having TFT circuits;

    a common electrode arranged opposite to the 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 pixel electrodes and the common electrode based on an image signal;

    a touch detection electrode provided opposite to the common electrode and forming capacitance between the touch detection electrode and the common electrode; and

    a gate buffer coupled with gates of the TFT circuits through each of gate lines,wherein the gate buffer is switched to be coupled with one of a first-L line and a first-H line through a first switch, andwherein the gate buffer is coupled with a second line.
