Patent ID: 10269886

Abstract:
An organic electroluminescent display device and a manufacturing method thereof are disclosed. The organic electroluminescent display device includes a substrate, a first thin film transistor disposed on the substrate, a second thin film transistor disposed on the first thin film transistor, a first light emitting element electrically connected with a drain of the first thin film transistor, wherein the first light emitting element comprises a first electrode, a first light emitting layer and a second electrode which are stacked, a second light emitting element electrically connected with a drain of the second thin film transistor, wherein the second light emitting element is disposed on the second thin film transistor and comprises a third electrode, a second light emitting layer and a fourth electrode, wherein the second light emitting element is configured to emit white light. By forming the second light emitting element on the second thin film transistor, an original non-display region of the organic electroluminescent display device becomes a display region, as a result, an aperture ratio of the organic electroluminescent display device is increased, and the display effect of the organic electroluminescent display device is improved.
