An electroluminescent display device includes a substrate on which a display area and a non-display area are defined. A thin film transistor is in the display area on the substrate. A light-emitting diode is connected to the thin film transistor and includes a first electrode, a light-emitting layer and a second electrode. A first link line is disposed in the non-display area and applies a first voltage to the first electrode. A second link line is spaced apart from the first link line in the non-display area. A conductive pattern is disposed in the non-display area and is connected to the second electrode to apply a second voltage. The conductive pattern has an opening corresponding to the first link line.
