摘要：
A polarizing plate of the present invention comprises a polarizer; an adhesive layer; and a transparent protective film bonded to at least one side of the polarizer with the adhesive layer interposed therebetween, wherein the adhesive layer is formed from an active energy ray curing adhesive containing at least one curable component, and the adhesive layer has a glass transition temperature (Tg) of 60° C. or more, and a thickness of 0.01 μm an to 5 μm. The polarizing plate has sufficient durability in a severe environment at high temperature and high humidity.
