Abstract: A display device includes a substrate including a non-transmissive area and a transmissive area, where the non-transmissive area has a first emission area, and the transmissive area has a second emission area. The display device further includes a first light emitting element disposed in the non-transmissive area and including a first anode electrode, a second light emitting element disposed in the transmissive area and including a second anode electrode, a thin film transistor disposed in the non-transmissive area and configured to drive at least the second light emitting element, and a transparent electrode electrically connecting the thin film transistor to the second anode electrode of the second light emitting element. Further, the structures of the first anode electrode and the second anode electrode are different from each other.
