Abstract
A lighting apparatuscomprising light sourcesfor emitting light, a plurality of light reflection portionsformed on the reflection side for reflecting light incident from the light sources, and a linear photoconductorfor causing the light to exit from the exit side opposed to the reflection side, the planes of the plurality of reflection portions being respectively tilted at angles which converge the light to the human eyes watching. Angles of the light reflection portions are set so that exit angles of light exiting from the linear photoconductor are required angles, whereby the lighting apparatus can have a uniform light intensity distribution. The application of the lighting apparatus can provide a liquid crystal display of good display characteristics.
