PROBLEM TO BE SOLVED: To provide a light diffusion sheet that is formed with a rear surface sticking prevention layer on a surface opposite to a light diffusion layer of a base material sheet and that is prevented from warping.SOLUTION: A light diffusion sheet comprises: a transparent base material sheet 1 having flexibility; a light diffusion layer 3 overlapping on one surface of the base material sheet; and a rear surface sticking prevention layer 11 overlapping on the other surface of the base material sheet. The light diffusion layer 3 and the rear surface sticking prevention layer 11 respectively include: a large number of transparent fine granular bodies 7, 13 that are dispersedly arranged; and binders 9, 15 for holding the fine granular bodies on each surface of the base material sheet. The binder 9 of the light diffusion layer 3 is made of non-cross-linked resin, and the binder 15 of the rear surface sticking prevention layer 11 is made of cross-linked resin. |
