POLARIZER, A METHOD FOR MANUFACTURING THE SAME, A POLARIZING PLATE, AN OPTICAL FILM AND AN IMAGE DISPLAY, CAPABLE OF SUPPRESSING THE DETERIORATION OF THE OPTICAL PROPERTY UNDER HIGH TEMPERATURE CONDITIONS

摘要

PURPOSE: A polarizer, a method for manufacturing the same, a polarizing plate, an optical film and an image display are provided to improve the durability of a polarizer by suppressing the orientation of a molecular chain.;CONSTITUTION: A polarizer is continuously formed with a stretchable film. The stretchable film is formed by processing a film with at least two color and dyeing it. The film is obtained from a polyvinyl alcohol resin, more than two carboxylic acid, or more than acid anhydride group more than the carboxyl group having a anhydride of 1000 molecular weight.;COPYRIGHT KIPO 2010
