A display device includes a timing controller configured to generate a first control signal using a first clock signal when driven at a first frame frequency, and generate a second control signal using a second clock signal when driven at a second frame frequency different from the first frame frequency, pixels connected to scan lines, data lines, and emission control lines, and an emission driver configured to supply an emission control signal to the emission control lines in response to an emission start signal included in the first control signal or the second control signal. The number of off periods of the emission control signal included in one frame driven at the first frame frequency is equal to the number of off periods of the emission control signal included in one frame driven at the second frame frequency.
