METHOD FOR MANUFACTURING POLARIZING MEMBERS COMPRISING LOCALLY BLEACHED REGION, METHOD FOR MANUFACTURING POLARIZING MEMBER ROLLS, AND METHOD FOR MANUFACTURING SINGLE-TYPE POLARIZING MEMBERS

摘要

The present invention relates to a method for manufacturing a polarizing element including locally bleached areas including steps of providing a polarizing element including a polyvinyl alcohol-based polarizer in which at least one or more of iodine and dichroic dye is oriented in a certain direction; partially bleaching the polyvinyl alcohol-based polarizer by bringing a bleaching solution into contact with one surface of the polyvinyl alcohol-based polarizer through a printing method; and correcting an appearance of the partially bleached polarizing element.
