  • a plurality of data lines which extend in a first direction;

    a plurality of sensing output lines which extend in a second direction which is not parallel to the first direction and transmit a sensing output signal;

    a pixel electrode which is connected with a data line of the plurality of data lines through a switching element;

    a touch sensor which is connected to the data line and a sensing output line of the plurality of sensing output lines and detects a touch; and

    a data driver which disconnect the plurality of data lines from each other to apply displaying data voltages to the respective data lines during an image display period of a frame, and connect a portion of the data lines to each other to form a plurality of sensing input lines to apply sensing input signals to the plurality of sensing input lines during a touch sensing period of the frame after the image display period,wherein the touch sensing period is included in a vertical blank period of the frame.
