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 liquid crystal display device is also provided with a liquid crystal panel driving device (2) which drives the liquid crystal panel in accordance with an input gray scale. The counter electrode substrate includes a convex section in each pixel 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. The convex section is provided such that the liquid crystal layers of the light reflection section has an aligned state and the liquid crystal layer of the light transmission section has an alignment state. The liquid crystal panel driving device (2) carries out gray scale transition enhancement processing in which the input gray scale is corrected in accordance with gray scale transition. This makes it possible to realize a liquid crystal display device that has high display quality (especially, high display quality of a moving image) and carries out a display in a transmission mode and a reflection mode.
