Abstract:
An LED device that includes electrodes patterned over a substrate; the pattern forming several first electrodes separated by inter-electrode spacers. One or more light-emitting layers are formed over the first electrodes. A patterned conductive layer is formed over the one or more light-emitting layers and over the first electrodes in regions external to the inter-electrode spacers. A continuous unpatterned conductive layer is formed over both the patterned conductive layer and the inter-electrode spacers. Finally, a combination of the patterned and continuous unpatterned conductive layers form a single, bi-layered, electrically continuous second electrode.
