Claim:
1. A method for manufacturing an optical display device by sequentially peeling a plurality of optical film sheets together with an adhesive layer from a carrier film, the optical film sheets being continuously supported via the adhesive layer on one of opposite surfaces of a long web of the carrier film which configures an optical film laminate, and laminating the plurality of optical film sheets to one of opposite surfaces of respective ones of a plurality of panel components via the adhesive layer by using a laminating unit at a predetermined laminating position, the method comprising: a first step of, after completing lamination of a preceding optical film sheet to one of opposite surfaces of a preceding panel component at the predetermined laminating position, winding the carrier film in a state where another surface thereof folded to inside at a tip-end configuring a head portion of a peeling member and the carrier film is passed around the peeling member, and forwardly feeding a leading end of the optical film sheet supported on the carrier film to a leading end detecting position defined between the tip-end of the peeling member and the predetermined laminating position; a second step of operating a film leading end detecting means when the leading end of the optical film sheet is stopped at the leading end detecting position where a first head-out state is established, to read the leading end of the optical film sheet; a third step of forwardly feeding the leading end of the optical film sheet from the leading end detecting position to the predetermined laminating position where a second head-out state is established, while further peeling the optical film sheet together with the adhesive layer from the carrier film by further winding the carrier film; a fourth step of forwardly feeding the panel component to be laminated to the optical film sheet from a predetermined waiting position to the predetermined laminating position; and a fifth step of laminating the optical film sheet and the panel component via the adhesive layer while further peeling the optical film sheet together with the adhesive layer from the carrier film, when the panel component and the leading end of the optical film sheet arrive at the predetermined laminating position.
