The present invention relates to an organic light emitting display device capable of reducing the power consumption through supplying different driving voltages for the organic light emitting layers with different colors. An organic light emitting display device according to an embodiment of the present invention includes: a substrate; a thin-film transistor formed on the substrate; pixel electrodes which are formed on the thin-film transistor and include a first to third organic light emitting layer; a first common electrode formed on the first organic light emitting layer; a second common electrode formed on the second organic light emitting layer; and a third common electrode formed on the third organic light emitting layer. The first common electrode and the second common electrode are insulated from each other.
