PURPOSE: To provide an optical film effective for improvement in visual field angle characteristic. CONSTITUTION: At least one sheet of light control plates are obtd. by forming a compsn. contg. >=2 kinds of photopolymerizable monomers and/or oligomers varying in refractive indices from each other to films, then irradiating the films with UV rays. This optical film is obtd. by laminating at least one sheet of phase difference films consisting of a thermoplastic resin and having an intra-surface retardation value of 50 to 300nm and a ratio of (intra-surface retardation value)/(retardation value in the thickness direction) of 0.5 to 1.8 and polarizing films. |
