The present disclosure relates to a mask film used for manufacturing a polarizing plate having a locally bleached area, and a polarizing plate manufactured using the same.

Mask film and method for manufacturing polarizing plate by using same

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.

Methods for manufacturing polarizing element, polarizing element roll and single sheet type polarizing element having local bleaching areas

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.
