Polarizing plate and method of producing polarizing plate
A method of producing a polarizing plate according to an embodiment 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.
