Continuous roll of optical function film, method of manufacture of liquid crystal display element employing same, and optical function film laminating device
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（中）：

本发明的目的是减轻从具有在其宽度方向上具有刻痕线的连续辊馈送光学功能膜并将光学功能膜粘合在液晶面板上时在液晶显示元件中发生的条纹显示不均匀。 连续卷包括光纤膜层压体（15），其为卷绕成卷的连续幅材的形式，并且至少包括光学功能膜（10）和可释放地放置在光学功能膜上的载体膜（13） 10）。 光学功能膜（10）通过沿光学膜层叠体（15）的宽度方向形成的刻痕线（16）分割为多个切割片。 可以通过使光学功能膜的单位纵向长度的弯曲刚度落在特定范围内来解决问题。
