Abstract: The flame retardant thermoplastic resin composition includes about 100 parts by weight of a polycarbonate resin; about 5 parts by weight to about 30 parts by weight of a rubber modified aromatic vinyl-based copolymer resin; about 10 parts by weight to about 30 parts by weight of an aromatic phosphoric acid ester compound; and about 5 parts by weight to about 100 parts by weight of fillers including wollastonite and talc, wherein a weight ratio of wollastonite to talc ranges from about 1:about 0.1 to about 1:about 0.5. In the flame retardant thermoplastic resin composition, wollastonite and talc are present in a specific ratio, which can provide excellent properties in terms of stiffness such as flexural modulus and bending characteristics, and flame retardancy.
