PROBLEM TO BE SOLVED: To obtain a laminated multilayer optical film in which the number of components is minimized, rigidity is increased in comparison with publicly known multilayer films, and lateral displacement between the composing films of the laminated film structure is reduced. SOLUTION: A joined multifunctional optical device is the multilayer optical film comprising two or more composing films. At least one of the composing films has an upper face and a lower face. The upper face includes a series of optical structures and a plurality of projecting spacing structures, the lower face is substantially flat. The composing films are joined together into a single film structure which has one or more gaps defined between the composing films. COPYRIGHT: (C)2005,JPO&NCIPI |
