Claim:
A light diffusing polycarbonate resin composition comprising (A) a polycarbonate resin comprising a polycarbonate copolymer which comprises a repeating unit represented by the general formula (I) shown below and a repeating unit represented by the general formula (II) shown below, which has a content of the repeating units of the general formula (II) of 1 to 30% by mass and which has a viscosity value of 30 to 71; and (B) a light diffusing agent compounded therein in an amount of 0.01 to 10 parts by mass per 100 parts by mass of the polycarbonate resin, wherein R 1 and R 2 each independently represent an alkyl group having 1 to 6 carbon atoms, X represents a direct bond, an alkylene group having 1 to 8 carbon atoms, an alkylidene group having 2 to 8 carbon atoms, a cycloalkylene group having 5 to 15 carbon atoms, a cycloalkylidene group having 5 to 15 carbon atoms, —S—, —SO—, —SO 2 —, —O—, —CO— or a linkage represented by the following formula (III-1) or (III-2): R 3 and R 4 each independently represent an alkyl group having 1 to 3 carbon atoms, Y represents a straight chained or branched chained alkylene group having 2 to 15 carbon atoms, n is an integer of 2 to 200 and a, b, c and d are each an integer of 0 to 4.
