PROBLEM TO BE SOLVED: To provide a highly light diffusible polycarbonate resin board having excellent initial tinting, light fastness, mechanical strength, light diffusion, and brightness without damaging transparency of a polycarbonate resin, which can be used to applications requiring high degree of optical properties, particularly preferably used in a light diffusion board used in a back light for a liquid crystal display device, etc. SOLUTION: The light diffusible polycarbonate resin board is formed by co-extruding a surface layer comprising a polycarbonate resin composition containing a specified UV-ray absorber as the essential ingredient on at least one surface of a substrate material comprising a polycarbonate resin composition containing a light diffusing agent consisting of specified silicone rubber particles as the essential ingredient and optionally polycaprolactone.
