ABSTRACT:
A construction for electroluminescent device includes a substrate and an electroluminescent stack which forms a step relative to the substrate. A transparent layer of protective material is placed atop the stack to bridge the step and create a smooth edge profile along the edge. A metallization layer is situated atop the layer of protective material and is coupled to the electroluminescent stack through vias in the protective material.
