LIGHT CONTROL FILM, ROLL OF LIGHT CONTROL FILM, AND DISPLAY DEVICE

WIPO Patent Application WO/2015/064493

A1

A light control film (6) in one mode of this invention comprises the following: a light-transmitting substrate (39); a light-diffusing section (41) provided in a first region of one surface of said light-transmitting substrate (39); a light-blocking layer (40) provided in a second region of said surface, said second region being the non-first-region part of said surface; and a hollow section adjacent to the light-diffusing section (41). The light-diffusing section (41), which forms a structure that has anisotropic light-scattering characteristics, has the following: a light-output end face that contacts the abovementioned surface of the light-transmitting substrate (39); a light-input end face that faces and has a larger surface area than said light-output end face; and a reflective surface that contacts the light-output end face and the light-input end face and reflects light inputted via the light-input end face. A mark (50) that indicates the direction of the anisotropy of the light-scattering characteristics of the light-diffusing section (41) is provided.
