摘要： A thermoplastic resin composition and a molded article including the same. The thermoplastic resin composition includes: about 100 parts by weight of a thermoplastic resin; about 1 to about 30 parts by weight of an additive for laser direct structuring (LDS additive); about 0.01 to about 5 parts by weight of a hindered phenol-based compound; about 0.01 to about 10 parts by weight of a sodium phosphate salt; about 0.01 to about 5 parts by weight of a phosphite compound; about 0.01 to about 5 parts by weight of a sulfonate compound; and about 0.01 to about 10 parts by weight of a metal oxide, wherein a weight ratio of the hindered phenol-based compound, the sodium phosphate salt, the phosphite compound and the sulfonate compound to the metal oxide may range from about 2:1 to about 10:1. The thermoplastic resin composition has good properties in terms of plating reliability and thermal stability (discoloration resistance) and can secure good injection molding stability by suppressing gas generation upon injection molding.
