Abstract
A liquid crystal display is disclosed. The liquid crystal display includes a clock generator generating a first input clock signal and then a second input clock signal; a level shifter shifting the first and second input clock signals and generating clock signals whose voltages decrease stepwise from a gate high voltage, to a modulation voltage that is lower than the gate high voltage, to a gate low voltage that is lower than the modulation voltage; and a liquid crystal panel that includes data lines, gate lines intersecting the data lines, TFTs provided at intersections of the data lines and the gate lines, and a gate shift register sequentially supplying a gate pulse to the gate lines in response to the clock signals input from the level shifter.
