Abstract
An optical film laminate that has predefined slit lines for enhancing both product accuracy and manufacturing speed in liquid-crystal display element manufacturing to radically improve manufacturing yield. The optical film laminate formed as a continuous web with the predefined slit lines for use in a continuous manufacturing system by laminating optically functional film sheets to liquid-crystal panels. The optical film laminate having defect-free regions having a predefined length corresponding to the dimension of a liquid-crystal panel and defective regions having a predefined length different from the defect-free region, based on the detected position of defects. The optical film laminate having a carrier film releasably laminated to an adhesive layer, wherein defect-free normal polarizing sheets and a defective polarizing sheets are formed on the carrier film by forming slit lines corresponding to above regions along the transverse direction of the optical film laminate.
