An apparatus for generating gamma voltage includes a plurality of gamma set generators and a gamma set selector. The gamma set generators generate a plurality of gamma voltage sets that include gamma voltages having different voltage levels from each other such that each gamma voltage set corresponds with a brightness mode. The gamma set selector selects any one of the gamma voltage sets in response to the brightness mode and drives data lines of a display device in accordance with the selected gamma voltage set.

A liquid crystal display device is discussed, which includes a first substrate and a second substrate, which face each other; a liquid crystal layer formed between the first substrate and the second substrate; and a column spacer formed between the first substrate and the second substrate, wherein the column spacer is formed within a light-shielding region on the first substrate or the second substrate, and a width of the light-shielding region in the periphery of the column spacer is greater than that of the light-shielding region where the column spacer is not formed. Since the width of the light-shielding region in the periphery of the column spacer is greater than that of the light-shielding region where the column spacer is not formed, even though an alignment film is damaged by the column spacer, light leakage can be prevented from occurring at the damaged portion.

A shift register employs only a thin film transistor of the same type channel and has a level shifter built-in. A shift register with a built in level shifter includes a plurality of stages and a plurality of level shifters. The stages are connected in cascade to shift a start pulse inputted through an input terminal and sequentially output the shifted pulse. The level shifters level-shift a voltage level of the shifted pulse applied from each of the stages and outputting it.
