1. An organic electroluminescent display device comprising:
a plurality of sub-pixels, each of the sub-pixels comprising an active area for displaying an image and an inactive area other than the active area, wherein a driving switching element is in the inactive area, and is configured to supply a driving current; and a power supply wire for supplying power to the sub-pixels, wherein the power supply wire comprises:
a first power supply wire extending in a first direction along long sides of the sub-pixels;a dummy power supply wire on the first power supply wire and electrically connected with the first power supply wire; anda second power supply wire extending in a second direction along short sides of the sub-pixels, and a protection electrode on the dummy power supply wire, the protection electrode covering the dummy power supply wire, wherein the dummy power supply wire comprises an opaque conductive material, and wherein the protection electrode comprises a transparent conductive material and is a same material as an anode of an organic light emitting diode driven by a driving signal of the driving switching element.
