Abstract: A display device includes a display panel including pixels, a data driver which applies a dithering data voltage to the display panel, and a driving controller which determines whether to perform a dithering operation of applying the dithering data voltage to the display panel based on input image data. The display device alternately changes the dithering data voltage in units of one frame when the dithering operation is performed at a first dithering frequency or a third dithering frequency, and alternately changes the dithering data voltage in units of N frames when the dithering operation is performed at a second dithering frequency.
