Abstract:
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 of iodine and dichroic dye is oriented in a certain direction; forming a mask layer including at least one punched area on one surface of the polarizing element; partially bleaching the polarizing element formed with the mask layer by immersing the polarizing element into a bleaching solution; and correcting an appearance of the partially bleached polarizing element.
