Abstract: A thermoplastic resin composition and a molded article produced therefrom. The thermoplastic resin composition includes about 100 parts by weight of a thermoplastic resin and about 0.5 to about 30 parts by weight of zinc oxide. The zinc oxide has a peak intensity ratio (B/A) of about 0.01 to less than about 0.1, where A indicates a peak in the wavelength range of 370 nm to 390 nm and B indicates a peak in the wavelength range of 450 nm to 600 nm in photoluminescence measurement. The thermoplastic resin composition can exhibit good properties in terms of deodorization, impact resistance, and the like.
