An object of the present invention is thin, the manufacturing method of the molded body and molded body made by forming a concave-convex pattern on the surface of the easy to process to a molded product, and light transmittance is high optical sheet and a method of manufacturing an optical sheet such as a large screen painter been achieved the light guide plate is to provide a, (a) less than the viscosity average molecular weight of 22 000 aromatic polycarbonate 100 parts by mass, and (B) containing parts of antioxidant 0.01 to 1 by weight, and not containing a blue dye or pigment an aromatic polycarbonate resin composition of the extruder after the extruded from the glass transition temperature or lower in an optical sheet cooling, is achieved by the optical sheet, characterized in that the total light transmittance of not less than 91% in the 0.1 ~ 1 ㎜ thickness of the optical sheet.
