Abstract: A display device includes pixels electrically connected to a plurality of scan lines and a plurality of data lines, respectively, a scan driver that provides a scan signal to each of the plurality of scan lines, a voltage supply that supplies a first gate voltage to the scan driver through a first gate power line, and a voltage compensator. The voltage compensator senses a partial voltage of the first gate voltage applied to the scan driver through a feedback line. The voltage compensator compensates the first gate voltage with a second gate voltage in case that the sensed first gate voltage is greater than a first reference voltage.
