Abstract: A display device includes a display panel, a scan driver outputting a scan signal, and a data driver. The scan driver includes a first sub-scan driver that receives a first start signal and an odd clock signal, and a second sub-scan driver that receives a second start signal and an even clock signal. The scan signal has an activation period corresponding to a horizontal period. The odd clock signal includes a first clock enable period and a first clock disable period, which are ‘k’ times greater than the horizontal period. The even clock signal includes a second clock enable period and a second clock disable period, which are ‘k’ times greater than the horizontal period. The first clock enable period and the second clock enable period alternate with one another.
