Abstract

A liquid crystal display device of the present invention includes a first transparent electrode layer and a second transparent electrode layer sandwiching a liquid crystal layer between, a light source for radiating the substantially collimated light to the liquid crystal layer, and a diffusion unit for diffusing the light which has just been transmitted through the liquid crystal layer. The diffusion unit is arranged on the first glass plate via a transparent polymer for forming the first transparent electrode layer and a first alignment layer. Then, on the second glass plate, the second transparent electrode layer and a second orientation film are formed. A liquid crystal is introduced into a space between the first orientation film and the second alignment layer film and the light source is arranged for completing the liquid crystal display device.
