ABSTRACT:
The present invention provides: a polycarbonate light diffusing resin composition in which a first discoloration is a little, and particularly a photo-deterioration caused by a cold-cathode tube as a light source of liquid crystal displays is suppressed; and a light diffuser panel obtained by molding the same.The polycarbonate light diffusing resin composition comprises: (A) 100 parts by mass of an aromatic polycarbonate resin; (B) 0.01 to 10 parts by mass of a light diffusing agent; and (C) 0.05 to 5 parts by mass of a light-resisting agent having a maximum absorption wavelength at 290 to 330 nm in an ultraviolet light absorption spectrum and the light diffuser panel is a light diffuser panel having a thickness of 0.5 to 2 mm and obtained by molding the polycarbonate light diffusing resin composition.
