Beschreibung
Zusammenfassung:	The present invention provides a roll of a continuous web (10) of an optical film laminate (15) with predefined slit lines (16) for use in a continuous manufacturing system by laminating optically functional film sheets to liquid-crystal panels. The optical film laminate (15) with predefined slit lines (16) comprises an optically functional film (11) having an adhesive layer (12) which is subjected to a preliminary inspection, and a carrier film (13) releasably laminated to the adhesive layer (12). 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 (13) by sequentially forming slit lines (16) along the transverse direction with respect to the lengthwise direction of the optical film laminate (15).
