PROBLEM TO BE SOLVED: To provide an optical resin molding, typically a light guide plate or a light diffusion plate, having excellent heat resistance, excellent non-hygroscopicity, and reduced warp and deformation under high-temperature and high-humidity. SOLUTION: The optical resin molding (a light guide plate or a light diffusion plate) is molded from a resin composition comprising 5 to 95 wt.% copolymer (A) comprising 1 to 10 wt.% alkyl (meth)acrylate monomer and 99 to 90 wt.% aromatic vinyl monomer and having a polystyrene-equivalent weight-average molecular weight of not smaller than 100,000 and a molecular weight distribution Mw/Mn of 1.8 to 3.0 and 95 to 5 wt.% polycarbonate resin (B).
