The light control film provides improved front luminance and appropriate diffusion without the problems of interference pattern, glare. The light control film has a rough surface that, for substantially any arbitrary cross section perpendicular to a base plane of the film, has an average .theta..sub.ave of absolute values of slope, with respect to the base plane of a curve along the edge of the cross section, which is not less than 20 degrees and not more than 75 degrees, and has an absolute value of skewness (JIS B0601:2001) of the profile curve of not more than 1.2.
