Polarizing Plate And Method Of Producing Polarizing Plate

There are provided a polarizing plate and a method of producing the polarizing plate by which a polarizing film can be produced without the occurrence of a problem such as peeling between a resin substrate and a polyvinyl alcohol-based resin layer, and after the production of the polarizing film, the polarizing film and the resin substrate can be peeled without limitations on a peel direction and a peel angle, and a polarizing plate excellent in external appearance can be obtained. The method of producing the polarizing plate according to an embodiment of the present invention includes: applying an application liquid containing a polyvinyl alcohol-based resin and a surfactant onto a resin substrate to produce a laminate in which a polyvinyl alcohol-based resin layer is formed on the resin substrate; stretching and dyeing the polyvinyl alcohol-based resin layer formed on the resin substrate to produce a polarizing film; laminating an optical functional film on a polarizing film side of the laminate to produce an optical functional film laminate; and peeling the resin substrate from the optical functional film laminate. A content of the surfactant in the application liquid is less than 1 part by weight with respect to 100 parts by weight of the polyvinyl alcohol-based resin.
