Abstract
The present disclosure relates to a data driving circuit and a display device including the same, and the data driving circuit includes a plurality of data input terminals to which pixel data of an input image is input, and a plurality of voltage input terminals to which gamma tab voltages for each color having different voltage levels, and common gamma tab voltages having different voltage levels are each input. When the input image includes pixel data having different grayscale values for each color, a data voltage of a corresponding color is changed when any one of the gamma tab voltages for each color is changed, and data voltages of all colors are changed when any one of the common gamma tab voltages is changed.
