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 pair of open/close lamination rollers 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, opening the lamination rollers and switching to non-active; a second step of 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, thereby forwardly feeding a leading end of the optical film sheet toward the predetermined laminating position where the lamination rollers are opened while peeling the optical film sheet together with the adhesive layer from the carrier film; a third step of stopping winding of the carrier film to retain the leading end of the optical film sheet at the predetermined laminating position where the lamination rollers are opened, and operating a film leading end detecting means to read the leading end of the optical film sheet retained at the predetermined laminating position where the lamination rollers are opened, when the leading end of the optical film sheet arrives at the predetermined laminating position; 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, by closing the lamination rollers and switching to active and winding the carrier film, when the panel component arrive at the predetermined laminating position where the leading end of the optical film sheet is retained.
