Abstract: Method for manufacturing an optical display device which allows for appropriately correcting a linear deformation generated on a pressure-sensitive adhesive layer in laminating an optical functional film with a panel member includes steps of peeling a sheet of optical functional film together with the pressure-sensitive adhesive layer from a carrier film up to a predetermined head-out length, stopping the conveyance of the carrier film for detecting the front edge, making the front edge of the sheet of optical functional film proceed to the laminating position, laminating from the front edge to a predetermined position upstream of the head-out length on the sheet of optical functional film with the panel member at a first lamination speed, and laminating at least a part from the predetermined position to a rear edge of the sheet of optical functional film with the panel member at a speed faster than the first lamination speed.

Abstract: A method for manufacturing an optical display device from a web of optical film laminate including a carrier film, a pressure-sensitive adhesive layer formed on one of opposite surfaces of the carrier film, and a plurality of sheets of optical functional film continuously supported on the carrier film via the pressure-sensitive adhesive layer, comprises folding the other of opposite surfaces of the carrier film inside via a tip end of a releasing body to wind the carrier film, peeling the sheet of optical functional film to a head-out state while exposing the pressure-sensitive adhesive layer, stopping winding of the carrier film, detecting a front end of the peeled sheet of optical functional film in the head-out state, and rewinding the carrier film integrally with the sheet of optical functional film in the head-out state to mend a deformation of a pressure-sensitive adhesive, at the tip end of the releasing body.
