摘要： The present invention relates to a polycarbonate resin composition including both of silicone oil and olefin-based wax at a proper ratio and thus having improved dispersibility of titanium dioxide in the composition as well as high impact strength and melt index (moldability), and also relates to a polycarbonate molded article made of the polycarbonate resin composition. The polycarbonate resin composition according to the present invention includes silicone oil and olefin-based wax at a proper ratio and thus improves dispersibility of titanium dioxide which is added to the composition to give whiteness, while preserving high impact strength and melt index (moldability), so that crawling which is generated on the surface of a final product of polycarbonate molded article is prevented and the appearance property of the molded article is improved. Therefore, the polycarbonate resin composition according to the present invention has characteristics of high whiteness as well as high impact strength and melt index (moldability), and thus is easily applicable to industries in need of the polycarbonate resin.
