Abstract
There are disclosed methods for driving liquid crystal display apparatuses for certainly completing in a short time to performing a transition of liquid crystal molecules to a displayable alignment in liquid crystal display apparatuses such that an initial alignment of the liquid crystal molecules is different from the displayable alignment, typically an optically compensated bend mode liquid crystal display apparatus. A voltage is applied to a liquid crystal layer until display area in the liquid crystal layer is transformed to the displayable alignment. After the completion of the transition, a backlight is switched on to sift to a display-driving mode. In order to complete the transition in a short time, voltage pulse under the conditions (such as a frequency and a voltage value) determined in accordance with a temperature of a liquid crystal panel is applied to the liquid crystal layer.
