ABSTRACT:
A light control film providing improved n front luminance and appropriate light diffusion, without problems of interference pattern, glare etc., has a rough surface constituted so that, for a curved surface portion of the rough surface, having an approximately square area of 1 mm2or larger and defined at an arbitrary position on the rough surface by using data for heights of the rough surface measured at predetermined intervals in the longitudinal and transverse directions, an average of slopes of the curved surface portion (θnvdegrees) of the rough surface, with respect to a base plane of the film, should be not less than 27 degrees and not more than 70 degrees at substantially any position on the light control film.
