Abstract: A driving method of an LCD device driving a liquid crystal display device including the steps of deriving a frame detection signal from a data enable signal by detecting a blank interval between frames deriving a start signal from the frame detection signal deriving a first gate clock signal from the start signal deriving a second gate signal from the first gate clock signal wherein a rising time of the first gate clock signal is in a range between a falling time of the start signal and a rising time of the second gate clock signal.

Abstract: Liquid crystal display device and method for driving the same, which has a gate high voltage generating circuit for preventing flickering of a gate high voltage. The liquid crystal display device includes a gate high voltage generating circuit for generating a gate high voltage by using n (where n is a natural number greater than unity) pumping units and supplying the gate high voltage through an output line, and a voltage stabilizing unit for generating a gate high voltage within a range of a highest preset value by using an output voltage of the (n?1)th pumping unit in a case the gate high voltage generated at the gate high voltage generating circuit exceeds the highest preset value.
