1. A display device comprising:
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,
wherein, when the dithering operation is performed at a first dithering frequency or a third dithering frequency, which is smaller than the first dithering frequency, the dithering data voltage is alternately applied to the display panel in units of one frame, and
wherein, when the dithering operation is performed at a second dithering frequency, which is less than the first dithering frequency and greater than the third dithering frequency, the dithering data voltage is alternately applied to the display panel in units of N frames, wherein N is a natural number of 2 or greater,
wherein, when the second dithering frequency decreases, a value of N decreases, and
wherein, when the dithering data voltage is alternately applied to the display panel in units of N frames, a same dithering data voltage is applied to the display panel during N frames.
