Abstract:
A light-emitting diode (LED) device includes a reflective electrode and a transparent electrode having one or more light-emitting layers formed there-between. A contrast-enhancement element is located on a side of the transparent electrode opposite the light-emitting layer. The contrast-enhancement element has a first reflected-light absorbing layer and a second layer including transparent areas and reflective areas. The second layer is between the first reflected-light absorbing layer and the reflective electrode. A patterned light-scattering layer is located between the reflective areas of the second layer and the reflective electrode.
