Patent ID: 8414993

Claim:
A roll of a continuous web of an optical film laminate adapted for use in a system for sequentially manufacturing liquid-crystal display elements by laminating optically functional film sheets to respective ones of liquid-crystal panels, said optically functional film sheet having a predefined dimension corresponding to a dimension of the respective ones of liquid-crystal panels having a predefined size, wherein the optical film laminate comprising; an optically functional film with an adhesive layer including at least one defect-free normal sheet having no defect and at least one defect-containing sheet having at least one defect, the at least one defect-free normal sheet and the at least one defect-containing sheet being defined between two longitudinally adjacent ones of predefined slit lines based on a preliminary inspection and having the predefined dimension, wherein the preliminary inspection occurs prior to winding the optical film into a roll; and a carrier film releasably laminated on the adhesive layer, wherein said slit lines being sequentially formed, prior to winding the optical film laminate into the roll, in a transverse direction of said optical film laminate at a side opposite to said carrier film to a depth reaching a surface of said carrier film adjacent to said adhesive layer, wherein said at least one defect-free normal sheet and said at least one defect-containing sheet comprising identification means generated based on a position of defect detected by said preliminary inspection.
