摘要： Provided is a polycarbonate resin composition capable of providing a molded body that has a high light transmittance and high light-diffusing property, can be inhibited from yellowing, and has high thin-wall flame retardancy, and a polycarbonate resin molded body obtained by molding the polycarbonate resin composition. The flame-retardant light-diffusing polycarbonate resin composition has a viscosity-average molecular weight of 17,000 or more and includes, with respect to 100 parts by mass of a polycarbonate (A) formed of 10 to 100 parts by mass of a branched polycarbonate (A-1) and 90 to 0 parts by mass of an aromatic polycarbonate (A-2), 0.1 to 5 parts by mass of a light diffuser (B), 0.01 to 1.0 part by mass of a flame retardant (C), 0 to 0.5 part by mass of a polytetrafluoroethylene (D), and 0 to 2 parts by mass of a polyorganosiloxane (E), and the polycarbonate resin molded body is obtained by molding the polycarbonate resin composition.
