摘要： A liquid crystal panel (10) includes a liquid crystal layer formed with a p-type liquid crystal. The liquid crystal layer exhibits homogeneous orientation while no voltage is applied. Further, an electric field is applied to the liquid crystal layer in a direction same as dipole moments (μ) of liquid crystal molecules (3a) to which no voltage is applied. With these arrangements, it is possible to provide a liquid crystal panel and a liquid crystal display device, each of which adopts a new display mode that can achieve a wide viewing angle equivalent to an IPS mode, can achieve a high-speed response like an OCB mode or exceeding the OCB mode, and does not require an initial operation for orientation conversion to the bend orientation.

摘要： 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 shift 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.
