PROBLEM TO BE SOLVED: To provide a light-diffusing double layer sheet having remarkably improved light diffusibility in comparison with a conventional light-diffusing sheet, and usable for a luminaire requiring high-degree light diffusibility, for example, LED illumination.SOLUTION: There is provided a light-diffusing double layer sheet formed by laminating a layer comprising inorganic oxide particles and a layer comprising metal alcoholates on at least one surface of a glass fiber sheet; a light-diffusing double layer sheet preferably, using colloidal silica, more preferably, having a total light transmittance of 45% or higher and a parallel light transmittance of 5% or lower. |
