Method for manufacturing polarizing film |
| abstract |
An object of the present invention is to reduce variations in optical characteristics in the width direction of a polarizing film. A method for manufacturing polarizing film according to the present invention manufactures a polarizing film from a polyvinyl alcohol-based resin film, and comprises in this order a treatment step of bringing a treatment liquid into contact with a polyvinyl alcohol-based resin film for performing treatment, and a cleaning step of bringing a cleaning liquid into contact with the polyvinyl alcohol-based resin film for cleaning, wherein in the cleaning step, when the width of the polyvinyl alcohol-based resin film is used as reference and divided into one end portion including one end in the width direction of the polyvinyl alcohol-based resin film, the other end portion including the other end in the width direction, and a central portion which is in the inner side of the one end portion and the other end portion in the width direction, the polyvinyl alcohol-based resin film is such cleaned that a degree of cleaning of the one end portion is larger than the degree of cleaning of the other end portion, and the degree of cleaning of the other end portion is larger than the degree of cleaning of the central portion. |
