Abstract: A display device includes a display unit comprising a plurality of pixels. A touch sensing unit is disposed on the display unit and comprises a plurality of driving electrodes and a plurality of sensing electrodes. A touch driver supplies a touch driving signal to the driving electrodes through a plurality of driving lines and receives a touch sensing signal from the sensing electrodes through a plurality of sensing lines. During a first horizontal period of one frame period, the touch driver supplies a touch driving signal having a first pulse width to a first partial portion of the driving lines and supplies a touch driving signal having a second pulse width smaller than the first pulse width to a second partial portion of the driving lines that is different from the first partial portion of the driving lines.
