Beschreibung
Zusammenfassung:	Objects of this invention are providing a high-performance polarizing plate showing high transmittance, high degree of polarization and high contrast and exhibiting high thermal durability, especially high wet heat durability, an image display device including the same, and a method for manufacturing the polarizing plate. This invention provides a polarizing plate comprising: a polarizer element film which is a stretched film of a hydrophilic polymer adsorbing a dichroic dye, a transparent protective layer provided on both sides or one side of the polarizer element film, and at least one acrylic resin layer between the polarizer element film and the protective layer, Wherein the acrylic resin layer is obtained by curing a polymerizable resin composition and has a thickness of 5 to 10 [mu]m after curing, the polymerizable resin composition containing a (meth) acrylate component containing a (meth) acrylate (A) having hydroxyl group, and a photopolymerization initiator, the (meth) acrylate component having a to
