Abstract: A method of manufacturing a display device includes forming an uncut electrode on a substrate, at least a portion of the uncut electrode being formed in a non-emission area; disposing a first insulating layer to overlap the uncut electrode; removing at least a portion of the first insulating layer in the non-emission area; cutting the at least a portion of the uncut electrode in the non-emission area; disposing light emitting elements including a first light emitting element in an emission area and a second light emitting element in the non-emission area; and disposing a second insulating layer to overlap the emission area and the non-emission area. The second light emitting element is disposed in the non-emission area where the uncut electrode is not disposed. Also provided is a display device manufactured by the method.
