ABSTRACT:
A light illumination apparatus and a liquid crystal display using the apparatus, comprising a light source on a lateral side and a reflector on the backside of a light-pipe, further comprising an air layer between the light-pipe and the reflector, further comprising a light scattering control layer disposed at a portion of the light-pipe and having directivity in a direction substantially normal to the light emission plane, where total internal reflection of the incident light from the light source at an interface of the light-pipe is achieved, and a means for moving the predetermined region, wherein the time average amount of emitted light is substantially equal in each of all light emission regions, and there is time when the light emissive region substantially does not emit light.
