To provide a polycarbonate resin composition excellent in low-birefringence and strength.Disclosed is a polycarbonate resin composition prepared by blending a polycarbonate resin (A) prepared by forming carbonate bonds in a 95-5% by mole of dihydroxy compound represented by formula (1) and a 5-95% by mole of dihydroxy compound represented by formula (2) with a diester carbonate, and a polycarbonate resin (B) prepared by forming carbonate bonds in dihydroxy compound represented by formula (3) with a diester carbonate or phosgene in a 45-85% ratio by weight of (100×(A))/((A)+(B)). (in the formula, R1 and R2 represent a hydrogen atom or methyl respectively.)
