Abstract:
A display device with a touch sensor having a display function and a touch sensor function is provided. The display device includes a first substrate including a pixel electrode; a first electrode along a first direction; and a second substrate including a second electrode that includes patterns of electrodes along a second direction crossing the first direction and that faces the first electrode and the pixel electrode, wherein upon the display function being activated, the pixel electrode is supplied with a pixel signal, and the second electrode is supplied with common voltage, and upon the touch sensor function being activated, the first electrode is applied with a first signal and the second electrode is configured to receive the first signal to be a second signal as a touch detecting signal.
