Abstract: A display device includes a substrate; an organic light-emissive layer disposed on the substrate; and a cathode electrode layer disposed on the organic light-emissive layer, wherein the cathode electrode layer includes: a first electrode layer disposed on the organic light-emissive layer; a second electrode layer disposed on the first electrode layer; and a third electrode layer disposed on the second electrode layer, wherein the second electrode layer is a conductive organic material layer. The second electrode layer can absorb heat from laser to reduce damage to the third electrode layer. Thus, penetration of external defect-causing factors into the organic light-emissive layer through the third electrode layer can be reduced.
