Abstract: An electroluminescent display device includes a plurality of pixels that each comprise a portion of a substrate. A pixel dam is disposed over an intermediate layer over the substrate. An overcoat layer is in contact with the pixel dam, the overcoat layer having a planar top surface. An emitting diode is on the overcoat layer and includes a first electrode, a second electrode, and an emitting layer between the first electrode and the second electrode.

Abstract: An electroluminescent display device can include a substrate having a display area and a pad region; a thin film transistor in the display area; first and second pads in the pad region; an insulating layer covering the thin film transistor and the first and second pads; first and second pad contact holes exposing the first and second pads, respectively; a light-emitting diode electrically connected to the thin film transistor and including first and second electrodes and a light-emitting layer interposed therebetween; and first and second auxiliary pads on the insulating layer, the first and second auxiliary pads being electrically connected to the first and second pads, respectively, in which each of the first electrode and the first and second auxiliary pads includes a first layer formed of a transparent conductive material and a second layer formed of a metallic material, and a surface length between the first and second auxiliary pads is greater than a distance between the first and second auxiliary pads.
