Abstract
There is provided an aromatic polycarbonate resin composition exhibiting excellent mechanical strength, transfer property, light transmittance, thermal stability and moldability which is capable of being molded into thin-wall products and large-size products, as well as a light guide plate produced from the resin composition. The present invention relates to an aromatic polycarbonate resin composition for light guide plates, comprising an aromatic polycarbonate resin having a viscosity-average molecular weight of 13,000 to 15,000, and a ratio of a weight-average molecular weight to a number-average molecular weight (Mw/Mn) of 1.5 to 2.7 in terms of polystyrene as measured by gel permeation chromatography; and a stabilizer and a releasing agent blended in the aromatic polycarbonate resin, as well as a light guide plate produced from the resin composition.
