Abstract
A liquid crystal display device has a vertical alignment type liquid crystal panel. The vertical alignment type liquid crystal panel is provided with an active matrix substrate whereupon a light reflection pixel electrode for reflecting light and a light transmission pixel electrode for transmitting light are provided in each pixel section; a counter electrode substrate; and a liquid crystal layer made of a liquid crystal material having negative dielectric anisotropy. The counter electrode substrate includes a convex section so that the liquid crystal layer in the light reflection section has the thickness thinner than that in the liquid crystal layer of the light transmission section. A liquid crystal panel driving device carries out gray scale transition enhancement processing in which the input gray scale is corrected in accordance with gray scale transition.
