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.
