    摘要: 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.

    摘要: A lamp guarding unit 26 of a backlight 20 for a liquid crystal display is detachable from a lamp holding unit 24 fixed to a light-guiding plate 22 in a direction perpendicular to a light illumination surface of the light-guiding plate 22. Therefore, in replacing a fluorescent tube 44, it is not necessary to replace the whole backlight 20 or for the user to touch the fluorescent tube 44, which is difficult to handle. Because of the perpendicular removal, only a small space is needed for the replacement. Thus, the fluorescent tube 44 can be replaced safely and easily, and only a small space is required for this replacement.
