Abstract: A display device includes a display panel, a data driving circuit, a scan driving circuit, and a driving controller. The driving controller receives an image signal and a control signal and controls the data and scan driving circuits to display an image on the display panel. The driving controller divides the display panel into first and second display regions based on the image signal, and outputs start and masking signals indicating starts of one frame and the second display region, respectively. First and second frames have first and second durations, respectively. The scan driving circuit sequentially drives scan lines in synchronization with the start signal and stop the driving of scan lines, corresponding to the second display region, of the scan lines, in response to the masking signal.
