Abstract: A display device includes a display panel including pixels, and a timing controller which determines a first dimming period and a second dimming period based on a maximum luminance, determines an emission off ratio of the pixels as a first off ratio increasing discretely as the maximum luminance decreases in the first dimming period, and determines the emission off ratio as a second off ratio in the second dimming period.
