A display device including: a liquid crystal panel assembly including pixels; a data driver applying a data voltage to lines which is connected to the pixels; and a common voltage generator providing voltage to the liquid crystal panel assembly, in which the voltage is an optimal voltage for a maximum grayscale at which a flicker is minimized while a maximum grayscale is applied to the pixels, the data driver applies the data voltage with the minimum grayscale to the data lines so that a negative data voltage with a minimum grayscale is higher than the common voltage by a first voltage level or more, and each of the pixels includes a first subpixel and a second subpixel, and when the data voltage is applied to the pixel, a pixel voltage of the first subpixel and a pixel voltage of the second subpixel are different.
