Abstract: A display device includes a display panel including a plurality of pixels, a timing controller which generates an emission start signal, an emission driver which supplies an emission control signal to the plurality of pixels based on the emission start signal received from the timing controller, a first scan driver which supplies a first scan signal to the plurality of pixels, a second scan driver which supplies a second scan signal to the plurality of pixels, and a data driver which supplies a data signal to the plurality of pixels. The timing controller adjusts a period in which the emission start signal is supplied based on a change of a driving frequency.
