Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical film, with which manufacturing efficiency and yield, when manufacturing a thin optical film comprising a liquid crystal substance layer without support substrate can be significantly improved. SOLUTION: In the manufacturing method of the optical film, half-cutting is performed to a laminated film which is constituted by laminating a repeelable film/ a hardened acrylic resin layer/ the liquid crystal substance layer with fixed alignment/ a hardened acrylic resin layer/ an adhesive layer/ a separator film, in this order. Then the repeelable film is peeled off. COPYRIGHT: (C)2007,JPO&INPIT
