Disclosed is a light diffusion film which exhibits good light diffusibility and good light resistance, while having excellent economic efficiency and excellent adhesion to other members. Specifically disclosed is a light diffusion film wherein an adhesive layer, which is mainly composed of a polyolefin resin containing a polar group, is arranged on at least one surface of a light diffusion layer, which is mainly composed of two kinds of polyolefin resins that are incompatible with each other, in such a manner that the adhesive layer forms the outermost surface of the light diffusion film. The light diffusion film is characterized in that the total light transmittance of the film is 66-100% and the haze of the film is 20-100%. A backlight device is configured by bonding the adhesive layer surface of the light diffusion film onto the base surface of the light exit surface of a backlight base unit. |
