MULTI-LAYER LIGHT DIFFUSING LIGHT GUIDING PLATE, BACK LIGHT UNIT COMPRISING THE SAME, AND DISPLAY DEVICE COMPRISING THE SAME

摘要

A multi-layer light diffusing light guide plate, a backlight unit comprising the same are provided to improve the brightness and uniformity of the brightness, and prevent wrinkle of a sheet on the light guide plate. A transparent base layer(210) consists of an optical transparent resin. A light diffusion layer(220) is placed on the transparent base layer, and diffuses light. A diffusion layer comprises 1~50 weight in which the average particle diameter is 10~50mum about the optical transparent resin(222) part. A light-diffusing agent(223) disperses to the optical transparent resin. A minute protrusion are formed on the surface of the diffusing layer.
