A polarizing plate having excellent durability is provided. An average surface roughness of a bonding surface of a polarizer and a cyclic olefin resin film bonded to at least one surface of the polarizer, the bonded surface of the cyclic olefin resin film with the polarizer. A polarizing plate characterized in that Ra is 10 nm or more and 200 nm or less, and the contraction rate in the transmission axis direction of the polarizer is 20% or less after the polarizer is left in an atmosphere at a temperature of 105 ° C. for 10 hours. is there.
