    摘要： A method of producing an optical panel assembly including the polarizing film in a continuous manner by laminating a polarizing film to a surface of a rectangular-shaped optical panel, is disclosed. The polarizing film is formed by performing a step of subjecting a laminate comprising a continuous web of a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, 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 PVA type resin layer to 10 µm or less, and a step of causing a dichroic material to be absorbed in the PVA type resin layer. A plurality of slits are formed in a carrier film-attached optical film laminate prepared by releasably attaching a carrier film to the optical film laminate with the polarizing film through an adhesive layer, in a width direction thereof at lengthwise given intervals corresponding to one of long and short sides of the optical panel, to extend from a surface of the optical film laminate to a depth reaching a surface of the carrier film facing the adhesive layer to thereby form an optical film laminate sheet between lengthwisely adjacent two of the slits. The laminate is fed to a lamination position in such a manner that each of the sheets becomes synchronous with a respective one of the optical panels being sequentially fed to the lamination position. Each of the sheets is peeled from the carrier film while allowing the adhesive layer to be left on the side of the optical film laminate, and the peeled sheet is laminated to the optical panel fed to the lamination position, through the adhesive layer.
