Abstract: A see-through organic light emitting display device including a light emitting region having a transparent anode, an organic light emitting layer, and a transparent cathode, and a see-through region having a transparent auxiliary electrode, which is configured to transmit external light. The transparent auxiliary electrode can be made from the same material as the transparent anode and separated from the transparent anode, and the transparent cathode extends into the see-through region so as to be electrically connected with the transparent auxiliary electrode.
