Zusammenfassung:	Disclosed is a method for fabricating an optical film. The optical film is of a laminate structure in which at least a first film and a second film are laminated, the method for fabricating the optical film includes a coating step, that is, a coating liquid is coated on a lamination surface of the first film and the second film by using a gravure roll coating manner of a gravure roll. Meanwhile, in the coating step, widths of the coating liquids deposited between the first film and the second film and the gravure roll in a film traveling direction, that is, liquid bead widths, are set to 4 to 20 mm.
