Stage: PROBLEM TO BE SOLVED: To provide a polarizing plate in which a decrease in transmittance in a high temperature environment is suppressed.SOLUTION: Disclosed a polarizing plate which includes: a polarizing element in which a dichroic dye is adsorbed and aligned on a polyvinyl alcohol resin layer; a first transparent protective film laminated on one surface of the polarizing element; and a second transparent protective film laminated on the other surface of the polarizing element. The polarizing element and the transparent protective film are bonded together by a first adhesive layer formed of a first adhesive containing a first compound. The polarizing element and the second transparent protective film are bonded together by a second adhesive layer formed of a second adhesive containing a second compound. The first compound is at least one kind selected from the group consisting of urea, urea derivative, thiourea and thiourea derivative, and the second compound has a nitroxy radical or a nitroxide group.SELECTED DRAWING: None (Grant)
