摘要： A method of producing a roll of an optical film laminate including a polarizing film having a thickness of 10 μm or less is described. The method includes providing a roll of a separator film-attached optical film laminate formed by subjecting a laminate comprising a continuous web of a thermoplastic resin substrate and a polyvinyl alcohol type resin layer to a 2-stage stretching consisting of a preliminary in-air stretching and an in-boric-acid-solution stretching, to reduce a thickness of the polyvinyl alcohol type resin layer to 10 μm or less. The method further includes causing a dichroic material to be absorbed in the polyvinyl alcohol type resin layer. The method further includes detecting a defect existing in the optical film laminate and the adhesive layer and upon detection of a defect, recording a position of the defect. The method further includes winding into a roll a separator film-attached optical film laminate.
