1. A polarizing plate, comprising:
a polarizer; an active energy beam-curable adhesive layer; and a pressure-sensitive adhesive layer, which are sequentially disposed, wherein the active energy beam-curable adhesive layer includes an adhesive composition including an epoxy compound and an acryl-based monomer in a cured state, wherein the epoxy compound includes an alicyclic epoxy compound and a glycidyl ether-type epoxy compound, wherein the pressure-sensitive adhesive layer includes a first pressure-sensitive adhesive layer forming a first surface; and a second pressure-sensitive adhesive layer forming a second surface, and the first and second surfaces include pressure-sensitive adhesive layers having different tensile modulus, wherein the active energy beam-curable adhesive layer is directly attached to at least one surface of the polarizer, and the first surface of the pressure-sensitive adhesive layer is directly attached to the adhesive layer, wherein the first surface has a higher tensile modulus than the second surface, wherein the first surface has a tensile modulus at 25° C. of 1 to 1,000 MPa, and wherein the second surface has a tensile modulus at 25° C. of 0.01 to 1.0 MPa. |
