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 modified polymer which can serve as a raw material of novel reverse dispersion retardation films is provided, the modified polymer having no need to select a plurality of monomers or polymers in order to realize a reverse dispersion and having no problems concerning glass transition temperature or the like in drawing treatment. A polymer having a polyol skeleton as its main chain is caused to react with a compound for modification such as an aromatic carboxylic acid hydride. Through this reaction, a modified polymer in which a chemical group such as an aromatic carbonyl group is bonded to an oxygen atom in a side chain of the polyol skeleton is prepared. For example, polyvinyl alcohols and benzoyl chloride can be used as the polymer and the compound for modification, respectively. The chemical group may be a benzoyl group. When this modified polymer is formed into a film and then subjected to drawing treatment, a retardation film which exhibits a reverse wavelength dispersion characteristic can be obtained.
