Abstract: A display device includes a display panel including first to (m*n−1)th pixel rows and a dummy pixel row, where each of m and n is a natural number greater than or equal to 2, an emission driver which provides emission signals to the first to (m*n−1)th pixel rows and the dummy pixel row, and a timing controller which provides an emission start signal and a dummy start signal to the emission driver. Each of the emission signals includes a plurality of on-periods and a plurality of off-periods in one frame period, and time points of off-periods of an emission signal provided to the dummy pixel row are the same as time points of off-periods of an emission signal provided to each of k*nth pixel rows, where k is a natural number greater than or equal to 1 and less than m.
