The present disclosure relates to a liquid crystal display device, and particularly, to a gamma voltage generating circuit capable of increasing a gamma point without an addition buffer and without increasing a chip size, and a liquid crystal display (LCD) device including the same. By adding a gamma point by utilizing an output buffer for inputting a reference voltage, a gamma curve may be minutely adjusted without increasing cost and a size.

Gamma voltage generating circuit and liquid crystal display device including the same

A liquid crystal display is provided comprising an LCD panel including data lines formed along a column direction, gate lines formed along a row direction perpendicular to the column direction, and a plurality of pixels arranged in a matrix pattern at intersections of the data lines and the gate lines, a data driver that supplies data voltages to the data lines, and a gate driver that sequentially supplies gate pulses to the gate lines. Subpixels of each of the pixels share one data line through which a data voltage is sequentially charged to the subpixels in a time-division manner. A column-directional length of each of the subpixels is longer than a row-directional length of each of the subpixels.
