    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: Disclosed is a method of producing a roll of an optical film laminate strip including a polarizing film which has a thickness of 10 μm or less. The method comprises the steps of: forming a continuous web of optical film laminate including a polarizing film which consists of a polyvinyl alcohol type resin layer and has a thickness of 10 μm or less, wherein the polarizing film is formed by performing an stretching sub-step of subjecting a laminate comprising a continuous web of thermoplastic resin substrate and a polyvinyl alcohol type resin layer formed on the substrate, to a uniaxial stretching in a lengthwise direction of the laminate based on 2-stage stretching consisting of preliminary in-air stretching and in-boric-acid-solution stretching, to attain a stretching ratio of 5 to 8.5 to thereby reduce a thickness of the polyvinyl alcohol type resin layer to 10 μm or less, and an absorption sub-step of causing a dichroic material to be absorbed in the polyvinyl alcohol type resin layer; cutting the continuous web of optical film laminate along a direction parallel to the length direction to form at least one continuous web of laminate strip having a given width; and winding the continuous web of laminate strip having the given width into a roll.

    Abstract: A method of producing a roll of a continuous web of an optical film laminate, usable in a process of laminating an optical film sheet including a polarizing film and formed to a size corresponding to that an optical panel to a surface of the optical panel being fed to a lamination position, is disclosed. The polarizing film is prepared by subjecting a laminate including a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, to uniaxial 2-stage stretching to reduce a thickness of the PVA type resin layer to 10 μm or less, and causing a dichroic material to be absorbed in the PVA type resin layer. A carrier film is releasably attached to the continuous web of optical film laminate including the polarizing film, through an adhesive layer. A defect inspection is performed for the optical film laminate and the adhesive layer.
