Abstract
Provided is a display device including a level shifter generating an output clock swinging between a first voltage and a third voltage during a display period and swinging between a second voltage and the third voltage during a touch sensing period. Waveform distortion of a no-load alternating current (AC) signal may be prevented without eliminating a stabilizing capacitor of the level shifter, and thus, sensing sensitivity may be increased by reducing noise of a touch sensor signal.
