Patent ID: 8264438

Claim:
A liquid crystal display device, comprising: an active matrix substrate on which a light reflection pixel electrode for reflecting light and a light transmission pixel electrode for transmitting light are formed in each pixel section; a counter electrode substrate; a vertical alignment type liquid crystal panel having a liquid crystal layer that is made of a liquid crystal material having a negative dielectric anisotropy; and a liquid crystal panel driving device for driving the liquid crystal panel in accordance with an input gray scale, wherein: the counter electrode substrate includes a convex section in said each pixel so that the liquid crystal layer in a light reflection section has a thickness thinner than that in a light transmission section; the liquid crystal layer in the light reflection section has an alignment state, and the liquid crystal layer in the light transmission section has an alignment state; and the liquid crystal panel driving device carries out gray scale transition enhancement processing in which the input gray scale is corrected in accordance with a gray scale transition; and wherein the gray scale transition enhancement processing is carried out so as to adapt to a response of the light reflection section faster than a response of the light transmission section due to difference in thickness of the liquid crystal layer.
