Abstract
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.
