Abstract
In a transmission liquid crystal display apparatus, light rays emitted from a light source and reflected from a mirror are collimated by a collimator lens and incident in a liquid cell structure through a polarization layer. The light rays emerged from the structure are transmitted through an another polarization layer and diffused by a diffusion layer. The diffusion light rays pass through a filter layer to a viewer.
