A method of manufacturing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate including a resin substrate having a long shape and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate, to thereby produce a polarizing film on the resin substrate; laminating an optically functional film on a side of the polarizing film of the laminate, to thereby produce an optically functional film laminate; and cutting widthwise direction end portions of the optically functional film laminate. The cut portions include the resin substrate, the polarizing film, and the optically functional film.

Method of manufacturing polarizing plate

Provided is a polarizing film that is excellent in external appearance and can contribute to improving the display characteristics of an image display apparatus. A polarizing film of the present invention includes a polyvinyl alcohol-based resin film containing iodine. At least one surface side of the polyvinyl alcohol-based resin film includes a low-iodine layer.

Polarizing film and method for producing polarizing film

A method of manufacturing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate having a resin substrate and a polyvinyl alcohol-based resin layer formed on at least one side of the resin substrate to produce a polarizing film on the resin substrate; laminating an optically functional film on the laminate on a polarizing film side to produce an optically functional film laminate; and peeling the resin substrate from the optically functional film laminate. The peeling is performed so that an angle &#x3b1; formed between a surface of the optically functional film laminate immediately before the peeling and a peeling direction of the resin substrate is smaller than an angle &#x3b2; formed between the surface of the optically functional film laminate immediately before the peeling and a peeling direction of the polarizing film.
