Abstract: A display device includes: a display panel including a plurality of pixels connected to a plurality of scan lines; a scan driving circuit, which drives the plurality of scan lines in synchronization with a clock signal; and a driving controller, which outputs the clock signal. While an operating mode is a multi-frequency mode, the driving controller comparts the display panel into a first display area and a second display area. A hold frame of the multi-frequency mode includes a first section during which the first display area is driven, and a second section during which the second display area is driven. The driving controller outputs the clock signal of a normal power mode during the first section and outputs the clock signal of a low-power mode during the second section.
