<p>Disclosed is a polycarbonate resin composition characterized by being composed of 100 parts by weight of a resin component, which is composed of 97-99.95% by weight of a polycarbonate resin (A) and 0.05-3% by weight of a polystyrene resin (B) having a weight average molecular weight of 1,000-18,000, and 0.02-2 parts by weight of a phosphorus antioxidant (C) and/or a phenolic antioxidant (D). Also disclosed is a molded article for optical use, which is made from such a polycarbonate resin composition. Since the polycarbonate resin composition is excellent in luminance, light transmittance, mechanical properties, heat resistance and hue stability, it is free from hue change or deterioration of the resin itself even when molded into a thin light guide plate (having a thickness of about 0.3 mm). Consequently, the polycarbonate resin composition is extremely high in commercial use value.</p> |
