Disclosed is a light diffusion plate for use in a backlight unit of a liquid crystal display or an illumination apparatus, which includes polycarbonate resin or polystyrene resin as a base resin, so that appropriate brightness and high hiding properties or appropriate hiding properties and high brightness are exhibited, and thus, while minimizing the use of additional optical films, brightness is sufficiently high, therefore maintaining good light emission quality. The diffusion plate has high ability to hide a light source, is inexpensively manufactured, and has high dimensional stability, so that no curling occurs even under high-temperature and high-humidity conditions, leading to excellent light properties.
