Abstract: A method of producing a roll of an optical film laminate strip including a polarizing film includes 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; 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.

Abstract: A system for manufacturing an optical display device includes providing a roll of a belt-shaped sheet material including an optical film and a release film, which has score lines previously formed by cutting layers of the material other than the release film. The optical film is bonded to a rectangular optical display unit of the display device. In the bonding steps, a first optical film is divided by the score lines into pieces each having a length corresponding to a long side of the display unit, and a second optical film is divided by the score lines into pieces each having a length corresponding to a short side of the display unit. The first optical film has a first polarizing plate whose longitudinal direction is parallel to its absorption axis, and the second optical film has a second polarizing plate whose longitudinal direction is parallel to its absorption axis.
