PROBLEM TO BE SOLVED: To provide a light-diffusing sheet such that luminance in the front direction can be increased while high light-diffusion is exhibited without using a prism sheet which is expensive, easily damaged on the surface and is difficult to handle, and that when the light-diffusing sheet is handled to be used to constitute the back light of a liquid crystal display sheet, damages are not given to the rough surface of the light-diffusing layer. SOLUTION: A light-diffusing layer 2 having a rough surface produced by dispersing resin particles which have a substantially spherical form and has 16.0 to 30.0μm average particle size and <50.0% coefficient of variation in the distribution of the particle size in a binder resin is applied on a transparent supporting body 3.
