LIGHT GUIDE PANEL FOR LIQUID CRYSTAL DISPLAY HAVING LIGHT DIFFUSION MATERIAL AND BACK LIGHT UNIT USING THEREOF

摘要

A light guide panel for a liquid crystal display having a light diffusion material and a back light unit using the same are provided to remove a dark part and a light part from an end part and an edge part by diffusing sufficiently light therefrom. A light guide panel for a liquid crystal display includes a lateral surface(201) for receiving incident light, a front surface(203) connected with the lateral surface in order to output the light, and a rear surface(205) for reflecting the light. A front prism(210) is installed in the front surface of the light guide panel for the liquid crystal display. The front prism has a predetermined sectional surface. A light diffusion material is distributed onto a surface or inner and outer surfaces of the front prism. An optical pattern is formed on the rear surface in order to reflect the light.
