摘要:
An organic electroluminescence display device includes: a substrate; a first electrode including a first sub-electrode and a second sub-electrode spaced apart from each other and on the substrate; a first light emitting unit on the first electrode; a charge generation unit on the first light emitting unit; a second light emitting unit on the charge generation unit; and a second electrode on the second light emitting unit, wherein the first light emitting unit comprises a first light emitting layer correspondingly on the first sub-electrode; and a second light emitting layer correspondingly on the second sub-electrode, wherein the second light emitting unit comprises a third light emitting layer correspondingly on the first light emitting layer; and a fourth light emitting layer correspondingly on the second light emitting layer.
