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; is excellent in a blocking prevention effect and a sticking prevention effect; and has sufficiently high light permeability and strength of the rear surface sticking prevention layer.SOLUTION: A light diffusion sheet comprises: a transparent base material sheet having flexibility; a rear surface sticking prevention layer formed on one surface of the base material sheet; and a light diffusion layer formed on the other surface of the base material sheet. The rear surface sticking prevention layer includes: a large number of first transparent fine granular bodies that are dispersedly arranged with intervals between them; and a first binder (holding layer) for holding the first fine granular bodies in a fixing manner. A portion of the first fine granular bodies protrudes from the surface of the holding layer. The first fine granular bodies have dispersion density of 50-300 pieces/mmon the surface of the rear surface sticking prevention layer, and fine granular bodies having grain sizes in the range of 6-12 μm accounts for 90 mass% or more in the whole first fine granular bodies. |
