Abstract: A display device includes a display panel including a pixel and an emission line connected to the pixel, an emission driver which provides an emission signal defining emission periods and non-emission periods to the emission line, and a controller which determines an emission cycle corresponding to a number of the discontinuous emission periods during a frame period and an emission-off ratio which is a ratio of a sum of the non-emission periods to the frame period. An nth frame period between an n−1th frame period and an n+1th frame period in which the emission cycles are different and the emission-off ratios are equal includes first to mth sub-frame periods in which the emission-off ratios are different.
