Abstract

A method of producing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate including a resin substrate and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate to produce a polarizing film on the resin substrate; laminating a first protective film on the polarizing film on an opposite side to the resin substrate; and peeling the resin substrate, followed by laminating a second protective film on the polarizing film on a side from which the resin substrate has been peeled. The laminating of at least one of the first protective film and the second protective film is performed through an adhesive having a moisture content of 10% or less.
