A display device includes a display including scan lines, data lines, light emission control lines, and pixels connected thereto, a scan driver configured to sequentially provide scan signals to the scan lines, a data driver configured to provide data signals to the data lines, a light emitting driver configured to provide light emission control signals to the light emission control lines based on a light emission clock signal having pulses, and a timing controller configured to provide the light emission clock signal to the light emitting driver, to output the pulses of the light emission clock signal during a frame in a first mode, to mask at least one pulse of the pulses during a first period of the frame in a second mode, and to output at least another pulse of the pulses during a second period after the first period.
