Abstract: An electroluminescent display device includes a substrate having an emission region and a bezel region, a bank layer that extends from the emission region to the bezel region, a plurality of signal lines which are disposed on different layers on the substrate, a first metal layer that overlaps the plurality of signal lines and has a step, a second metal layer that is disposed on the first metal layer, and an intermediate layer between the first and second metal layer. A step or curvature above the first electrode may be offset by the first intermediate layer so that incident from the outside is inwardly reflected. Therefore, a failure that a user at the outside recognizes the reflected light may be solved.
