1. An organic light-emitting display apparatus having a scan line and a data line, the apparatus comprising:
a first emission unit comprising a first organic light-emitting device configured to emit light in at least a first direction and through a first display surface, wherein the first organic light-emitting device comprises a first pixel electrode;a first opposite electrode facing the first pixel electrode, and a first organic emission layer disposed between the first pixel electrode and the first opposite electrode;
a second emission unit comprising a second organic light-emitting device configured to emit light in a second direction opposite to the first direction and through a second display surface opposing the first display surface, wherein the first emission unit and the second emission unit are alternately disposed, and the second organic light-emitting device comprises a second pixel electrode, a second opposite electrode facing the second pixel electrode, and a second organic emission layer disposed between the second pixel electrode and the second opposite electrode;
a transmissive area disposed adjacent to but not overlapping with the first emission unit and the second emission unit when viewed from a direction perpendicular to the first display surface, and configured to transmit external light through the first and second display surfaces in the transmissive area, wherein the transmissive area does not overlap the first opposite electrode and the second opposite electrode; and
a circuit unit which is electrically connected to the first emission unit and the second emission unit,
wherein the circuit unit comprises;
a first emission TFT and a second emission TFT, the first emission TFT comprising a first electrode, a second electrode and a gate electrode, and the second emission TFT comprising a first electrode, a second electrode and a gate electrode; and
a switching TFT and a driving TFT, the switching TFT comprising a first electrode, a second electrode and a gate electrode, and the driving TFT comprising a first electrode, a second electrode and a gate electrode,
wherein the first electrode of the first emission TFT is electrically connected to the second emission TFT, and the second electrode of the first emission TFT is electrically connected to the first organic light-emitting device,
wherein the first electrode of the second emission TFT is electrically connected to the first emission TFT, and the second electrode of the second emission TFT is electrically connected to the second organic light-emitting device,
wherein the gate electrode of the switching TFT is connected to the scan line and the first electrode of the switching TFT is connected to the data line,
wherein the gate electrode of the driving TFT is connected to the second electrode of the switching TFT, and the second electrode of the driving TFT is connected to the first electrodes of the first and second emission TFT,
wherein the first organic light-emitting device is arranged apart from the second organic light-emitting device, and from the direction perpendicular to the first display surface, the first emission TFT and the second emission TFT overlap the second emission unit, not the first emission unit,
wherein the first pixel electrode and the second pixel electrode are disposed to be spaced apart from each other in a third direction,
wherein the apparatus further comprises a third pixel electrode and the fourth pixel electrode, the third and fourth pixel electrodes being spaced apart from each other in the third direction, being spaced apart from the first pixel electrode and the second pixel electrode, and being disposed between the first pixel electrode and the second pixel electrode in the third direction, and
wherein the transmissive area extends from the first pixel electrode to the second pixel electrode in the third direction.
