Abstract
Provided is a display device capable of improving image quality. The display device includes a display panel, a gate driver, a data driver and a gamma reference voltage generator. In the display panel, gate lines and data lines cross each other to define a plurality of liquid crystal cells. The gate driver supplies a scan signal to the gate lines sequentially. The data diver supplies a data voltage to the data lines. The gamma reference voltage generator selectively supplies a gamma reference voltage or a reference voltage of black gradation to the data driver in each horizontal period, according to a selection control signal input from the timing controller.
