Abstract: Disclosed is a pressure sensitive adhesive-equipped polarizing plate (100) including a first pressure sensitive adhesive sheet arranged on one principal surface of a polarizing plate containing a polyvinyl alcohol-based polarizer. The polarizing plate includes a transparent protective film bonded to the second principal surface of the polarizer, and a urethane layer having a thickness of 0.1 to 10 μm disposed in contact with the first principal surface of the polarizer. The value XD2 of the first pressure sensitive adhesive sheet disposed on the urethane layer is 1×10−7 g/24 h or more, where X is a water-vapor permeability of the pressure sensitive adhesive sheet, and D is a thickness of the pressure sensitive adhesive sheet.
