PROBLEM TO BE SOLVED: To provide a polarizing plate in which a transparent protective film is bonded to a polarizer composed of a polyvinyl alcohol-based resin film via a photocurable adhesive, and the polarizer and the protective film are strongly bonded to each other.SOLUTION: There is provided a polarizing plate in which a transparent protective film is bonded via an adhesive layer to at least one surface of a polarizer composed of a polyvinyl alcohol-based resin film in which a dichroic dye is adsorbed and aligned, wherein the adhesive layer is a layer obtained by curing a photocurable adhesive containing (B) 1 to 10 pts.wt. of a photo-cation polymerization initiator and (C) 0.5 to 19 pts.wt. of a diol compound, based on 100 pts.wt. of a photo cation curable component containing (A) (A1) 50 to 90 wt.% of a diepoxy compound having an alicyclic ring and two epoxy groups in the molecule and (A2) 10 to 50 wt% of a reactive aliphatic compound selected from an aliphatic epoxy compound and an aliphatic vinyl ether compound by cation polymerization. |
