The purpose of the present invention is to provide: a high-performance polarizing plate which has high transmittance, high degree of polarization and high contrast, while exhibiting high heat durability, especially high wet heat durability; an image display device which is provided with this polarizing plate; and a method for producing a polarizing plate. The present invention provides a polarizing plate which is provided with: a polarizing element film that is a stretched film of a hydrophilic polymer, on which a dichroic dye is adsorbed; a transparent protective layer that is provided on both surfaces or one surface of the polarizing element film; and at least one acrylic resin layer that is arranged between the polarizing element film and the protective layer. This polarizing plate is configured such that the acrylic resin layer is obtained by curing a polymerizable resin composition so that the thickness after curing is 5-10 μm, said polymerizable resin composition containing a photopolymerization initiat
