1. A transparent display device, comprising:
a substrate including an emission area where a sub-pixel having an organic light emitting diode are disposed, and a transmission area where an auxiliary sub-pixel adjacent to the sub-pixel and having an auxiliary organic light emitting diode are disposed,
wherein the organic light emitting diode includes a 1-1 electrode in which a first transparent conductive layer, a reflective layer, a second transparent conductive layer and an intermediate insulating layer which is interposed between the reflective layer and the second transparent conductive layer,
wherein the first transparent conductive layer, the reflective layer and the intermediate insulating layer are disposed in the emission area, and the second transparent conductive layer is disposed to extend from the emission area to the transmission area,
wherein the auxiliary organic light emitting diode includes a 1-2 electrode in which the second transparent conductive layer is extended and provided, and
wherein the auxiliary organic light emitting diode are arranged to correspond to an entire transmission area.
