挠性偏振膜、其制造方法及图像显示装置
摘要：
本发明涉及一种挠性偏振膜，其具有厚度10μm以下的聚乙烯醇类起偏镜，所述聚乙烯醇类起偏镜是聚乙烯醇类树脂沿一个方向取向、且使碘或二色性色素吸附于上述聚乙烯醇类树脂并进行取向而成的，并且，该挠性偏振膜在实施了于上述聚乙烯醇类树脂取向的取向方向及与上述取向方向正交的方向反复进行U字状伸缩的U字伸缩试验后，在任一方向上都没有裂缝、折痕及漏光。本发明的挠性偏振膜即使使用了聚乙烯醇类起偏镜，也具有高度的柔软性(挠性)。
摘要（英）：

The present invention relates to a flexible polarizing film comprising a polyvinyl alcohol polarizer, not thicker than 10μm, in which polyvinyl alcohol resin is orientated in one direction and iodine or a dichromatic pigment is adsorbed and orientated on the polyvinyl alcohol resin, wherein the flexible polarizing film exhibits no breaking, traces of cracking or light-loss in either direction after being subjected to a U-shape flexing test in which the film is repeatedly flexed into a U-shape in the orientation direction in which the polyvinyl alcohol resin is orientated and the direction orthogonal to the orientation direction. The flexible polarizing film according to the present invention has a high level of flexibility despite using a polyvinyl alcohol polarizer.
