    Abstract: A method and an apparatus for manufacturing an optical display device by sequentially peeling a plurality of optical film sheets continuously supported on a long web of a carrier film and laminating the plurality of optical film sheets to a plurality of panel components are provided. After completing laminating operation of a preceding optical film sheet to a preceding panel component, a rear end of next optical film sheet, supported on a carrier film which in a state where one of opposite surfaces thereof is folded to inside at a tip-end of a peeling member, is read at a predetermined detecting position as positional information, then a leading end of an optical film sheet is positioned at a predetermined laminating position based on the positional information while peeling the optical film sheet from the carrier film.

    Abstract: The present invention provides a manufacturing apparatus and manufacturing method for realizing lamination with high accuracy responding to increase in speed and growth in size in an optical display unit manufacturing apparatus. The present invention is a manufacturing apparatus and manufacturing method in which, in the optical display unit manufacturing apparatus, a holding device which reciprocates between a peeling position and an upstream side predetermined position of the peeling position is deployed, the holding device holds the optical film laminate in a width-wise direction including both sides, and moves for a fixed distance, and at the peeling position, sends a front end of the optical film sheet peeled with the adhesive layer from the carrier film to a downstream side predetermined position of the peeling position to release the optical film laminate when the holding device reaches the lower side predetermined position.

    Abstract: A method for continuously manufacturing an optical display panel includes feeding a carrier film 12 on which an optical film 13 is placed with a pressure-sensitive adhesive interposed therebetween, peeling off the optical film 13 from the carrier film 12 by using a folding-back part 40a to inwardly fold back the carrier film 12 being fed, taking up the carrier film 12 from which the optical film 13 is peeled off, feeding an optical cell P and bonding the optical film 13, which is peeled off from the carrier film 12, to the optical cell P with the pressure-sensitive adhesive interposed therebetween, and reducing a difference between a first tension on the carrier film 12 located upstream of the folding-back part 40a and a second tension on the carrier film 12 located downstream of the folding-back part while reducing one of the first and second tensions before the bonding step.
