<P>PROBLEM TO BE SOLVED: To provide a technology capable of enhancing the durability of a polarizing film itself from a viewpoint of a concrete micro structure while maintaining high optical characteristics. <P>SOLUTION: A polarizing film forming method is provided in which at least a process for dipping a film into an aqueous solution containing a metal chelate agent is performed before at least a dyeing process in the forming of a polarizing film. Since a bridge of an amorphous area in the polarizing film can be achieved by the forming method, the polarizing film enhancing durability at a high temperature or in high temperature/high humidity environment by regulating local molecular motion while maintaining the high optical characteristics can be provided. <P>COPYRIGHT: (C)2010,JPO&INPIT |
