METHODS FOR MANUFACTURING POLARIZING ELEMENT, POLARIZING ELEMENT ROLL AND SINGLE SHEET TYPE POLARIZING ELEMENT HAVING LOCAL BLEACHING AREAS (AS AMENDED) |
| 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. |

1. A method for manufacturing a polarizing element including locally bleached areas comprising:
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; 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. |
