PROBLEM TO BE SOLVED: To provide a light-diffusing polycarbonate laminate in which an acrylic resin layer is laminated by a coextrusion method and which prevents a hurt made during handling from being conspicuous, is excellent in lightfastness and pencil hardness, and controls brightness nonuniformity. SOLUTION: In the light-diffusing polycarbonate laminate, when a polycarbonate resin (A) layer containing fine light-diffusing particles and an acrylic resin (B) layer containing an ultraviolet absorber and fine light-diffusing particles are coextruded, on at least one surface of the polycarbonate resin (A) layer of 1.0-2.0 mm, the thickness of the acrylic resin (B) layer containing the ultraviolet absorber and the fine light-diffusing particles 5-30μm in particle size is 20-50μm, and the polycarbonate resin (A) layer contains the fine light-diffusing particles having a particle size of 1-10μm and a refractive index of 1.40-1.46 in an amount of 0.1-3 wt.% of the laminate.
