Light diffusing resin composition and light diffusing plate using the same

摘要

Provided is a light diffusing resin composition, which, when molded into a large-plane light diffusing plate, is free of yellowing due to thermal deterioration, and can exhibit good light diffusing property, and a light diffusing plate using the resin composition. The light diffusing resin composition includes 100 parts by mass of a polycarbonate resin containing a polycarbonate copolymer (A) having repeating structural units represented by formulae (I) and (II) and 0.01 to 10 parts by mass of a light diffusing agent (B).
