A resin composition for a light diffusing plate is provided to realize properties such as high thermal resistance, low absorption, high brightness, and high light diffusion by using a methyl methacrylate/methacrylic acid/styrene terpolymer and a diffusing agent. A resin composition for a light diffusing plate is prepared by mixing a terpolymer 100.0 parts by weight and a light-diffusing agent 0.1~10.0 parts by weight. The terpolymer comprises a methyl methacrylate unit 10~40 weight%, a methacrylic acid unit 2~20 weight% and a styrene unit 40~88 weight%. The range of the average molecular weight is 80000~300000. The light-diffusing agent is at least one selected form partially crosslinked siloxane-based polymer particles, acrylic polymer particles or calcium carbonate. |
