Abstract: The present disclosure provides a display device including a display panel and a scan driver. The display panel displays an image. The scan driver includes a scan signal generation circuit disposed on one side of the display panel, and an emission signal generation circuit disposed on the other side of the display panel. The emission signal generation circuit outputs an emission signal having at least two Logic High sections in response to an external clock signal and a first scan signal output from the scan signal generation circuit.
