A display device that can reduce power and simplify a manufacturing process includes a display unit and a scan driver. The display unit includes a plurality of scan lines, a plurality of data lines, and a plurality of pixels. The scan lines are configured to receive a plurality of scan signals. The scan driver is configured to receive a synchronization signal that is generated in synchronization with a vertical synchronization signal, a first light emitting clock signal, a second light emitting clock signal representing the first light emitting clock signal shifted by a half cycle, a first initialization signal having a first phase delay relative to the second light emitting clock signal, and a second initialization signal having a second phase delay relative to the first light emitting clock signal. The scan driver is configured to generate a plurality of sequential driving signals and the plurality of scan signals.
