PURPOSE: A thermoplastic resin composition is provided to improve optical permeability and to have excellent thermal stability, mechanical strength, and processing balance. CONSTITUTION: A thermoplastic resin composition is obtained by mixing an acrylate-based resin into a polycarbonate base resin. The acrylate-based resin includes 0.05-2 parts by weight of a methylmethacrylate-styrene-acrylonitrile copolymer based on 100.0 parts by weight of the polycarbonate base resin. The weight average of the molecular weight of the methylmethacrylate-styrene-acrylonitrile copolymer is 30,000-150,000 g/mol. The weight average of the molecular weight of the polycarbonate base resin is 14,000-30,000 g/mol.
