Abstract: A light-emitting display device includes: a substrate including a first region and a second region spaced apart from each other, a first lower electrode at the first region, a second lower electrode at the second region, a first light-emitting layer having a first dopant on the first lower electrode of the first region, a second light-emitting layer on the second lower electrode of the second region, the second light-emitting layer having a second dopant different form the first dopant, the second light-emitting layer being configured to emit a light of a same color as that of the first light-emitting layer, and a common electrode on the first and second light-emitting layers, over the first and second regions.

Abstract: A light emitting display device can include a plurality of light emitting portions disposed on a substrate and a non-light emitting portion between the light emitting portions; first electrodes respectively disposed at the plurality of light emitting portions, the first electrodes being spaced apart from each other; a first stack, a charge generation layer and a second stack disposed on the first electrodes, the charge generation layer being disposed between the first stack and the second stack; and a second electrode disposed on the second stack. Also, the second electrode is connected to the first charge generation layer through a connection portion at the non-light emitting portion.
