    摘要： 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.
