Abstract

Embodiments of the disclosure relate to a display device and a data driving circuit. Specifically, there may be provided a display device comprising a display panel where a plurality of gate lines, a plurality of data lines, and a plurality of subpixels are disposed, a gate driving circuit configured to supply scan signals to the plurality of gate lines, a data driving circuit configured to convert digital image data into an analog data voltage and supply the analog data voltage to the plurality of data lines, a timing controller configured to control the gate driving circuit and the data driving circuit, a first gamma circuit generating a first gamma voltage corresponding to a first pixel during a period corresponding to a first color selection signal, and a second gamma circuit generating a second gamma voltage corresponding to a second pixel during a period corresponding to a second color selection signal different from the first color selection signal.
