摘要：
In an OCB liquid crystal display device, a gradation voltage of a video signal is set to be lower than a black display optimum voltage, and a reverse transition prevention voltage is set to be higher than the black display optimum voltage and to be lower than a maximum applied voltage, and as the gradation voltage of the video signal becomes low, the reverse transition prevention voltage is set to be high.
