Abstract
In a display device according to an embodiment of the present disclosure, a second electrode layer which has a higher melting point than that of the first electrode layer has high resistance to laser heat, such that damage thereto may be reduced even when a laser cutting process is performed. Thus, penetration of external defect-causing factors into an organic light-emitting layer may be reduced due to the second electrode layer constituting an outermost layer of the cathode electrode layer.
Claims19
A display device comprising:
- a substrate;
- a light-emitting layer disposed on the substrate;
- and
- a cathode electrode layer disposed on the light-emitting layer,
- wherein the cathode electrode layer includes:
- a first electrode layer disposed on the light-emitting layer;
- and
- a second electrode layer disposed on the first electrode layer,
- wherein each of the first electrode layer and the second electrode layer is a metal layer, and
- wherein the second electrode layer has a melting point higher than a melting point of the first electrode layer.
