Abstract
The present invention provides a light-diffusive polycarbonate-based resin composition which includes (A) 100 parts by mass of an aromatic polycarbonate resin, (B) 0.01 to 10 parts by mass of a light-diffusing agent, and (C) 0.1 to 20 parts by mass of a styrene-(meth)acrylic ester copolymer, and a light-diffusing plate formed from the composition. The light-diffusive polycarbonate-based resin composition can be injection-molded to form a light-diffusing plate having satisfactory precision in thickness for use in comparatively large liquid crystal displays having a size larger than 20 inches.
