Zusammenfassung:PROBLEM TO BE SOLVED: To provide an optical film capable of suppressing the occurrence of interference fringes, and to provide an optical display device equipped with the optical film. SOLUTION: In the optical film 1 formed of a plurality of transparent layers, a first transparent layer 2 constituting the optical film 1 and a second transparent layer 3 formed in contact with the first transparent layer 2 consist of materials having different refractive indexes and the occurrence of the interference fringes is suppressed because the contact interface 4 between the first transparent layer 2 and the second transparent layer 3 is a light scattering interface. The optical display device is equipped with the optical film. COPYRIGHT: (C)2005,JPO&NCIPI
