Abstract: The present invention relates to a driving method of a liquid crystal display device using an OCB (optically compensated birefringence) which realizes a wide view-field angle and high-speed response, and has an object of providing a driving method of a liquid crystal display device which method causes an OCB cell to transfer from a splay orientation state to a bend orientation state in short time.In a driving method of a liquid crystal display device using an OCB cell, gate on/off periods of a TFT are controlled at a start of a display operation, each pixel is caused to have bend orientation by a strong electric field that is generated between a gate electrode and a common electrode, and, at the same time, a voltage that is higher than that to generate an electric field necessary to maintain bend orientation is applied between a display electrode and the common electrode, to thereby effect transfer to bend orientation in short time.
