摘要:

A high-performance polarizing plate exhibiting high transmittance, high degree of polarization, and high contrast, and exhibiting high heat durability, particularly high moisture heat durability, and an image display apparatus provided with the same, and a polarizing plate The purpose is to provide a manufacturing method. A polarizing element film which is a stretched film of a hydrophilic polymer adsorbed with a dichroic dye, A transparent protective layer provided on both sides or one side of the polarizing film; It is a polarizing plate provided with an acrylic resin layer at least one layer between the above-mentioned polarizing element film and the above-mentioned protection layer, A polymerizable resin composition in which the acrylic resin layer has a thickness after curing of 5 to 10 μm and contains a (meth) acrylate component containing a (meth) acrylate (A) having a hydroxyl group, and a photopolymerization initiator A layer obtained by curing a polymerizable resin composition having a total hydroxyl value of 95 to 120 mg KOH / g of the (meth) acrylate component, Provided is a polarizing plate.
