Abstract
A display device can include a display panel comprising a first display area and a second display area that differ in the number of sub-pixels per unit area, a gamma part that generates a first area gamma voltage applied to the first display area and a second area gamma voltage applied to the second display area, and a data driver that generates data voltages by applying the first area gamma voltage to video data displayed in the first display area and applying the second area gamma voltage to video data displayed in the second display area and supplies the data voltages to the sub-pixels in the corresponding areas.
