Patent ID: 7443461

Claim:
A liquid crystal display device, comprising: a transmissive type liquid crystal display panel which sandwiches a liquid crystal layer between a pair of substrates; and a backlight arranged at a back face of the liquid crystal display panel and having a light source and a reflector, wherein the liquid crystal display device is configured to simultaneously perform as a transmissive display which transmits a light from the light source therethrough and as a reflective display which reflects an external light incident from a front face side of the liquid crystal display panel by the reflector, a polarizer is arranged between the back-face-side substrate of the pair of substrates and the backlight, the polarizer is formed to absorb polarized light having a predetermined polarization direction, at least two or more light diffusion layers are arranged between the back-face-side substrate of the pair of substrates and the reflector of the backlight to substantially diffuse the external light and minimize a shade from being viewed from an oblique direction, the at least two or more light diffusion layers include a first diffusion layer and a second diffusion layer, and a prism sheet is arranged between the first diffusion layer and the second diffusion layer.
