[MEANS FOR SOLVING PROBLEMS]
The present invention provides a continuous method and system for manufacturing liquid-crystal display elements, comprising and adapted to perform steps of, defining a plurality of defective-polarizing-sheet slitting positions and normal-polarizing-sheet slitting positions on a continuous web of an optical film, based on positions of defects existing in the continuous web of the optical film detected by a preliminary inspection, and applying a normal polarizing sheet to a liquid-crystal panel to manufacture a liquid-crystal display element, wherein the polarizing sheet formed to have a dimension corresponding to that of the liquid-crystal panel is formed from the continuous web of the optical film having slit-position information including the defective-polarizing-sheet slitting positions and normal-polarizing-sheet slitting positions recorded thereon, as encoded information, wherein the step comprises; calculating the feed-length measurement data based on the fed-out distance of the continuous web; reading the encoded information recorded on the continuous web; forming a plurality of slit lines by slitting the continuous web from the surface opposite to the carrier film along the slitting positons, based on the encoded information and the feed-length measurement data; determining whether the polarizing sheet defined between the slit lines sequentially formed in the continuous web, is a normal polarizing sheet or not, peeling the polarizing sheet determined to be the normal polarizing sheet from the carrier film and conveying to the lamination station; and applying the normal polarizing sheet to the liquid-crystal panel.
