PROBLEM TO BE SOLVED: To more selectively receive light incident on a film at a shallow angle and to give a light controlling property to a single polymer resin film itself by using a light controlling film which can transmit incident light without scattering in the film to simplify a manufacturing step of a light controlling film and to provide the film at a low cost. SOLUTION: In a transparent high polymer resin film, about in parallel with a molecule aligning direction of the high polymer resin film and in a film thickness direction, a stripe-shaped craze region is uniformly provided in an inclined direction to a film thickness direction and optical anisotropy is given to a single film itself.
