A display device may include a backlight unit, a display panel, and a backlight driver, and a panel driver. The backlight unit may include light source blocks including a first light source block. The display panel may include dimming regions including a first dimming region and respectively overlapping the light source blocks. The first dimming region may overlap the first light source block. The backlight driver may control a turn-on period and a turn-off period of each of the light source blocks. The panel driver may sequentially provide scan signals to the dimming regions for controlling light transmission of the dimming regions. A turn-off period of the first light source block may start before a scan period of the first dimming region and may end after the scan period of the first dimming region. The first dimming region may receive corresponding scan signals in the scan period.
