Patent ID: 8709567

Claim:
A roll of a carrier film-attached optical film laminate, usable in a process of continuously feeding a rectangular-shaped optical panel having a short side and a long side to a lamination position, and laminating an optical film sheet including at least a polarizing film and formed to a size corresponding to dimensions of the long and short sides, to one of two surfaces of the optical panel fed to the lamination position, wherein the carrier film-attached optical film laminate comprises: (a) a continuous web of an optical film laminate including at least a polarizing film formed to have optical characteristics satisfying the following conditions: P>−(10 0.929T−42.4 −1)×100 (where T<42.3); and P≧99.9 (where T≧42.3), wherein T is a single layer transmittance, and P is a polarization rate; and (b) a carrier film releasably attached to the optical film laminate through an adhesive layer under a condition that an adhesion force of the carrier film with respect to the adhesive layer is weaker than an adhesion force between the optical film laminate and the adhesive layer, to form a carrier film-attached optical film laminate, and wherein (c) the carrier film-attached optical film laminate is subjected to a defect inspection for the optical film laminate and the adhesive layer, and wherein (d) a plurality of slits are formed in the carrier film-attached optical film laminate in a width direction perpendicular to the lengthwise direction, at lengthwise given intervals corresponding to one of the 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, so that the carrier film-attached optical film laminate is formed as a continuous long sheet laminate having a structure in which a plurality of the sheets are continuously supported on the carrier film, and wherein: (e) when one of the plurality of optical film laminate sheets includes a defect detected by the defect inspection, an identification for identifying the sheet including the defect as a defective sheet is provided to the sheet including the defect; and (f) the continuous long sheet laminate with the identification is wound into the roll.
