A light diffusing plate having low water absorption, high hardness and excellent heat resistance is provided. SOLUTION: A composition comprising 5 to 40% by weight of methyl methacrylate units, 5 to 55% by weight of α-methylstyrene units and 20 to 90% by weight of styrene units, and having a weight average molecular weight range of 80,000 to 300,000. A resin composition for a light diffusing plate obtained by dispersing siloxane polymer particles, acrylic polymer particles, or calcium carbonate 0.1 to 2.0 parts partially crosslinked with respect to 100 parts of a polymer resin, and molding the resin composition Obtained light diffusion plate.
