摘要： The present disclosure relates to a polarizing plate including an adhesive layer, a primer layer and a polyethylene terephthalate film which are sequentially formed on at least one side of a polarizer, wherein the adhesive layer in the present disclosure is formed by an active energy ray-curable adhesive including a first epoxy compound of which a homopolymer has a glass transition temperature of 120° C. or higher, a second epoxy compound of which a homopolymer has a glass transition temperature of 60° C. or lower, and a cationic photopolymerization initiator, and wherein the primer layer is formed by a primer composition including one or more binder resins selected from the group consisting of polyester and polyvinyl alcohol-based resins, and one or more cross-linking agents selected from the group consisting of acrylic cross-linking agents, epoxy-based cross-linking agents and polyvinyl alcohol-based cross-linking agents.
