<P>PROBLEM TO BE SOLVED: To provide a technique with which durability of a polarizing film itself can be heightened from a viewpoint of a concrete micro structure while high optical characteristics are maintained. <P>SOLUTION: There is provided a manufacturing method of the polarizing film with which at least a treatment step of removing water contained in the polarizing film is performed under a super-critical condition. Since water contained in the polarizing film can be reduced to the limit thereof by using the manufacturing method, the polarizing film having enhanced durability under high temperature and high temperature and high humidity conditions can be provided by regulating local molecular motion while high optical characteristics are maintained. <P>COPYRIGHT: (C)2010,JPO&INPIT |
