| titleOfInvention | Manufacturing method of polarizer |
| abstract | The present application provides a method for producing a polarizing plate, which can obtain a polarizing plate having excellent optical properties. A method for producing a polarizer comprising at least a dyeing step, a crosslinking step, and a stretching step on a polyvinyl alcohol-based film, followed by a cleaning step and a drying step in this order, wherein the drying The step includes a step of drying while stretching the polyvinyl alcohol-based film in the conveying direction of the polyvinyl alcohol-based film, and the total stretching ratio after the washing step is defined as x, and the When the total draw ratio after the drying step is defined as y, the polyvinyl alcohol-based film satisfies the condition of formula (1): y>x. |
