1. A thermoplastic resin molded article made of a thermoplastic resin composition comprising:
a base resin including, in a weight ratio of 70:30 to 90:10, a first copolymer formed by graft polymerization of a diene-based rubber polymer having an average particle diameter of 50 to 200 nm with a first monomer mixture including an alkyl (meth)acrylate-based monomer and an aromatic vinyl-based monomer and a second copolymer which is a copolymer of a second monomer mixture including an alkyl (meth)acrylate-based monomer and an aromatic vinyl-based monomer; and
a plasticizer,
wherein the base resin is included in an amount of 100 parts by weight, and the plasticizer is included in an amount of 4 to 10 parts by weight, and
wherein the thermoplastic resin molded article has a haze of 2.0% or less, a flexural strength of 280 to 420 kg/cm2, and a flexural modulus of 11,000 to 13,500 kg/cm2.
