Abstract
The present disclosure relates to a gamma voltage generating circuit and a display device including the same. The gamma voltage generating circuit may include: a first output terminal to output a first gamma voltage set as a black grayscale voltage; a second output terminal to output a second gamma voltage set as a higher grayscale voltage than the black grayscale voltage; a third output terminal to output a third gamma voltage set as a highest grayscale voltage of the first pixel area; and a fourth output terminal to output a fourth gamma voltage set as a highest grayscale voltage of the second pixel area.
