Abstract:
1. A light-emitting diode (LED) device, comprising: a substrate; a reflective electrode comprising a reflective layer and a transparent, electrically-conductive layer and a transparent electrode having one or more light-emitting layers formed there-between formed over the substrate, the overlap of the reflective electrode, the transparent electrode and the one or more light-emitting layers defining a plurality of light-emitting areas; a contrast-enhancement element located over the substrate on a side of the transparent electrode opposite the light-emitting layer, the contrast-enhancement element having a first reflected-light absorbing layer and a second layer including transparent areas and reflective areas and wherein the second layer is between the first reflected-light absorbing layer and the reflective electrode; and a patterned light-scattering layer located in only a portion of each of the reflective areas of the second layer over the substrate between the reflective areas and the reflective electrode, wherein the patterned light-scattering layer is located between the reflective layer and the transparent, electrically-conductive layer.
