Abstract: A display device includes a display panel including pixels connected to scan lines, a scan driving circuit including scan stages corresponding to the scan lines, respectively, where each of the scan stages receives a masking signal and a carry signal and outputs a scan signal, and a driving controller which divides the display panel into the first display area and the second display area, controls the scan driving circuit such that the first display area and the second display area operate with different frequencies, and outputs start signals provided at different timings. A first scan stage disposed in the first display area from among the scan stages receives a first start signal of the start signals as the carry signal, and a first scan stage disposed in the second display area from among the scan stages receives a second start signal of the start signals as the carry signal.
