Abstract: A display device includes: a display panel including pixels connected to compensation gate lines, and a compensation gate driver which supplies compensation gate signals to the display panel. The compensation gate driver includes: a first compensation gate driver which generates the compensation gate signals based on a first-first clock signal and a second-first clock signal and a second compensation gate driver which generates the compensation gate signals based on a first-second clock signal and a second-second clock signal. The first-first clock signal and the second-first clock signal have the same waveform as the first-second clock signal and the second-second clock signal, respectively, during a scan period in which a compensation gate signal is supplied to the display panel, and have different waveforms from the first-second clock signal and the second-second clock signal, respectively, during a blank period in which the compensation gate signal is not supplied to the display panel.
