(57) [Summary] [PROBLEMS] To be used as a rear light frame of various LCD parts having excellent light reflectance. SOLUTION: The polycarbonate resin composition comprises: (A) Thermoplastic polycarbonate resin 1 as base resin (B) 2 to 20 parts by weight of titanium dioxide, (C) 0.01 to 5 parts by weight of sulfone sulfonate, and 0 to 30 parts by weight of (D) an impact reinforcing agent as an optional component. , (E) 0-30 parts by weight of a vinyl copolymer or (F) a stilbene-bisbenzoxazole derivative (st ilbene-bisbenzoxazole der ivive) 0-1.0 parts by weight. An inorganic filler, an ultraviolet absorber, a heat stabilizer, an antioxidant, a flame retardant, a lubricant, a dye or a pigment may be further added to the resin composition according to each application. The resin composition according to the present invention has excellent impact resistance and light reflectance, and thus is used for an LCD backlight reflector or a backlight frame. |
