Abstract
A display device of the invention includes a pixel unit including first pixels which display a first color; and a data driver which supplies first data voltages to the first pixels. The data driver includes: a first master gamma block including first master amplifiers which generate first reference gamma voltages; a first slave gamma block which generates first gamma voltages by dividing the first reference gamma voltages; and a first decoder which provides some of the first gamma voltages as the first data voltages, and each of the first master amplifiers is enabled or disabled based on a maximum luminance of the pixel unit.
