According to the present invention, there is provided a light diffusion film for diffusing incident light into an elliptical shape, which contains, inside the film, a structure composed of a plurality of flaky-shaped objects with comparatively high refractive index arranged in multiple rows in a region with comparatively low refractive index along any one arbitrary direction along the film plane. If T(μm) is the width of the flaky-shaped objects at a position of 50 μm below the upper end of the flaky-shaped objects in the direction of the thickness of the light diffusion film, and if L(μm) is the length of the flaky-shaped objects in the above-mentioned arbitrary one direction, the following relation (1) is satisfied:0.05≤<0.9  (1)
