PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition having a favorable hue and luminance without degrading characteristics inherent to a polycarbonate resin, that is, heat resistance, mechanical strength and the like, and also without causing whitening or reduction in transmittance for rays, and to provide an optical molded article such as a light guide plate, a surface light-emitting material and a nameplate obtained by molding the composition.SOLUTION: The polycarbonate resin composition comprises 100 parts by weight of a polycarbonate resin (A), 0.01 to 1 part by weight of a hydrogenated bisphenol A compound (B), and 0.02 to 1 part by weight of a phosphorus-based antioxidant (C). The polycarbonate resin composition shows excellent luminance, transmittance for rays, mechanical properties, heat resistance and hue stability, and therefore, even in molding the composition into a thin light guide plate (with about 0.3 mm thickness), the composition causes no change in the hue or no degradation in the resin itself, and has an extremely high industrial utility value. |
