[PROBLEMS] To produce a polarizing plate having good wettability and adhesion to a polyvinyl alcohol polarizing film and various protective films, retardation films and optical compensation films, low viscosity, good workability, and uneven adhesion. And providing an active energy ray-curable adhesive for polarizing plates having a high curing speed, having both high adhesive strength, high heat resistance and excellent transparency. An active energy ray-curable adhesive comprising an N-hydroxyalkyl (meth) acrylamide and an N-substituted amide monofunctional monomer as main components, a polarizing film and a polarizing layer protective film, A polarizing plate excellent in polarization, transparency and heat resistance is provided by laminating a retardation film or an optical compensation film and curing the film by irradiation with active energy rays.
