摘要： An objective of the present invention is to alleviate streaky display unevenness that occurs in liquid crystal display elements when feeding optical function film from a continuous roll having score lines in the width direction thereof and bonding the optical function film on a liquid crystal panel. A continuous roll comprises an optical film laminate (15) that is in the form of a continuous web wound into a roll and comprises at least an optical function film (10) and a carrier film (13) releasably placed on the optical function film (10). The optical function film (10) is divided into a plurality of cut pieces by score lines (16) formed along a widthwise direction of the optical film laminate (15). It is possible to resolve the problem by making the bending rigidity per unit longitudinal length of the optical function film fall within a specific range.
