Disclosed is a light-diffusion plate for use in a backlight unit of a liquid crystal display or an illumination apparatus. Specifically, this invention provides a light-diffusion plate including a substrate layer prepared by using a polycarbonate resin as a base resin. Thus, such a light-diffusion plate exhibits high dimensional stability thanks to high heat resistance and moisture resistance, and seldom causes a bending phenomenon even under conditions of high temperature and high humidity. Further, even if the light-diffusion plate is exposed to a light source for a long period of time, it has a low yellowing index. |
