PROBLEM TO BE SOLVED: To provide an optical film which prevents an operator from making an error in discrimination upon the assembling, can shorten operation labor times and can enhance the efficiency of structural arrangement by connectively disposing two films for condensing light rays and enhancing the luminance. SOLUTION: The optical film 10 is an integrally molded optical film and is provided with a first sheet 12, a second sheet 16 and a connective member 20 used for connecting the first sheet 12 and the second sheet 16. The first sheet 12 has a first structural surface and a first opposed surface, and the first structural surface has a plurality of first optical structures. The second sheet 16 has a second structural surface and a second opposed surface, and the second structural surface has a plurality of second optical structures. COPYRIGHT: (C)2007,JPO&INPIT
