<p>The present invention presents a light diffusing polycarbonate resin sheet obtained by coextruding a polycarbonate resin composition containing an antistatic agent as an essential component as a surface layer on at least one side of a base material comprising a polycarbonate resin composition containing a light diffusing agent as an essential component, wherein the antistatic agent of said surface layer is a specified organic sulfonic acid phosphonium salt and the concentration of said antistatic agent exceeds 2.0 parts by weight but is 10 parts by weight or less per 100 parts by weight of a polycarbonate resin used in the surface layer, and, when desired, polycaprolactone is present in 0.01 to 15 parts by weight per 100 parts by weight of the polycarbonate resin used in the surface layer. The light diffusing polycarbonate resin sheet of the present invention has excellent antistatic properties, light diffusion properties and luminance without adversely affecting the clarity of the polycarbonate resin and is ideal for use in light diffusing sheets particularly in those used in liquid crystal display device back lighting.</p> |
