Thermoplastic resin composition and molded article using the same

A thermoplastic resin composition, comprising:

• about 50 wt % to about 70 wt % of (A) a polyester resin comprising (A-1) a polybutylene terephthalate resin having an intrinsic viscosity of less than or equal to about 1.1 dl/g as measured according to ASTM D2857 and (A-2) a polyethylene terephthalate resin having an intrinsic viscosity of less than or equal to about 1.0 dl/g as measured according to ASTM D2857, wherein the polybutylene terephthalate resin (A-1) having an intrinsic viscosity of less than or equal to about 1.1 dl/g and the polyethylene terephthalate resin (A-2) having an intrinsic viscosity of less than or equal to about 1.0 dl/g are present in a weight ratio of about 1:1 to about 2:1,
• about 5 wt % to about 15 wt % of (B) a styrene-based copolymer,
• about 5 wt % to about 15 wt % of (C) a rubber modified vinyl-based graft copolymer, and
• about 5 wt % to about 25 wt % of (D) a glass fiber comprising (D-1) a first glass fiber having a length of about 2 mm to about 4 mm and (D-2) a second glass fiber having a length of about 10 μm to about 100 μm.
