DIFFUSION OPTICAL GUIDE PLATE FOR USE IN A LIQUID CRYSTAL DISPLAY

摘要

PURPOSE: A diffusion optical guide plate is provided to improve recognition degree of a user by forming a plurality of reflection protrusions of different diameters. CONSTITUTION: The diffusion optical guide plate comprises a reflection sheet(12) and a liquid crystal panel(13) which are disposed at lower and upper surfaces of the diffusion optical guide plate, respectively. A plurality of reflection protrusions(15) are protrusively formed at a lower surface(14) where a ray of light is reflected by the reflection sheet(12). The reflection protrusions(15) are formed so as to have a different diameter according to a position of a light source.
