ABSTRACT:
Disclosed is a microcavity organic light emitter having reduced variation in emission spectra per change in viewing angle. In an illustrative embodiment, a microcavity EL device comprises a microcavity layer structure stacked on a symmetric, non-planar surface of a substrate. The microcavity layer structure includes at least a first reflective layer on the non-planar substrate surface, a second reflective layer and an active layer having organic material capable of electroluminescence between the first and second reflective layers. The non-planar surface may be a shallow cone, frustum, a dome-like surface, or a combination thereof.
