Abstract

A method and a system for continuously manufacturing liquid-crystal display elements, using a continuous optical film laminate which comprises at least an optically functional film having an adhesive layer provided thereon and a carrier film releasably laminated on said adhesive layer, the optically functional film including at least one defect-free region and at least one defect-containing region, the defect-free region having a predefined length corresponding to a dimension of a liquid-crystal panel, the defect-containing region including at least one defect and defined as a region having a predefined length which is different from the length of the defect-free region, slit lines being sequentially formed to extend in a transverse direction of the optical film laminate to form defect-free, normal optically functional film sheets and defect-containing optically functional film sheets.
