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.

摘要： A method of manufacturing a polarizer is provided that makes it possible to manufacture a polarizer prevented from curling even when a liquid is brought into contact with a hydrophilic polymer film by being sprayed. A method of manufacturing a polarizer includes a swelling step A for swelling a hydrophilic polymer film 1 by bringing it into contact with a swelling liquid 2, a dyeing step B for dyeing the hydrophilic polymer film 1 by bringing it into contact with a dye liquid 3 containing a dichroic material, and a crosslinking/stretching step C for crosslinking the hydrophilic polymer film 1 by bringing it into contact with a crosslinking liquid 4 and further stretching it. In the method, the contact with the swelling liquid in the swelling step A is carried out in the gas phase by spraying the swelling liquid 2 onto both surfaces of the hydrophilic polymer film 1.
