摘要： A roll of a continuous web of an optical film laminate with predefined slit lines for use in a continuous manufacturing system by laminating optically functional film sheets to liquid-crystal panels. The optical film laminate with predefined slit lines comprises an optically functional film having an adhesive layer which is subjected to a preliminary inspection, and a carrier film releasably laminated to the adhesive layer. Defect-free normal sheets and defective or defect-containing sheets having predefined length corresponding to the dimension of the liquid-crystal panel are formed on the carrier film by sequentially forming slit lines along the transverse direction with respect to the lengthwise direction of the optical film laminate.
