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 composed mainly of a first base resin; and a surface layer composed mainly of a second base resin the same as or different from the first base resin of the substrate layer and including fluorine resin particles formed on either or both surfaces of the substrate layer. 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, the light-diffusion plate has excellent light properties including total luminous transmittance, and also has a low yellowing index even upon exposure to a light source for a long period of time. |
