The present invention relates to a display device, such as an organic electroluminescent device, for preventing corrosion of a signal line. A display device according to the present invention, comprising a substrate; a first electrode layer disposed over the substrate; a second electrode layer disposed to cover the first electrode layer and configured to electrically communicate with the first electrode layer; and a pixel disposed over the substrate, wherein a signal line is defined as an electrode layer including the first electrode layer and the second electrode layer, wherein the first electrode layer is in electrical communication with the pixel. The display device according to the present invention can prevent the material of the signal line from being corroded. Also, the device can prevent the reduction of brightness and the increase of power consumption.
