PURPOSE: Provided is a polycarbonate resin composition excellent in impact-resistance and light reflectivity, which can be used as a backlight reflector or a backlight frame of LCD. CONSTITUTION: The polycarbonate resin composition comprises 100pts.wt. of a thermoplastic polycarbonate resin as a base resin, 2-20pts.wt. of titanium dioxide, 0.01-5pts.wt. of a sulfone sulfonate salt, and selectively 0-30pts.wt. of an impact reinforcing agent, 0-30pts.wt. of a vinyl copolymer, and 0-1.0pts.wt. of a stilbene-bisbenzoxazole derivative. The titanium dioxide is a rutile type and has a median particle size of 0.15-0.25 micrometer.
