Claim:
A liquid crystal display comprising: a liquid crystal display panel on which a plurality of data lines and a plurality of gate lines cross each other; a data driving circuit for supplying a video data voltage and a black voltage to the data lines; a plurality of gate drive integrate circuits for sequentially supplying a gate pulse, synchronized with the video data voltage during a first period, to adjacent gate lines, and then simultaneously supplying a gate pulse, synchronized with the black voltage during a second period, to the gate lines spaced at intervals of one line; and a timing controller for generating data timing control signals for controlling the data driving circuit and gate timing control signals for controlling the gate drive integrate circuits, wherein the gate timing control signals include: a first gate start pulse generated only one time at the beginning of the first period and starting the shift operation of the gate drive integrate circuits; a second gate start pulse including a first pulse, a second pulse, and a third pulse continuously generated at the beginning of the second period and making the shift operation of the gate drive integrate circuits to be started, wherein a time difference between the second pulse and the third pulse of the second gate start pulse is more than that between the first pulse and the second pulse of the second gate start pulse; a first gate output enable signal generated during the first period, having a low logic period longer than a high logic period, and controlling the output of the gate drive integrate circuits; a second gate output enable signal generated during the second period, having a phase opposite to that of the first gate output enable signal, and controlling the output of the gate drive integrate circuits; and a gate shift clock having a pulse group including pulses generated more than three times and a pause period longer than the interval between the pulses and controlling the shift operation of the gate drive integrate circuits.
