Abstract

An inorganic light-emitting diode structure includes a transparent substrate and an inorganic semiconductor having a conduction layer and a light-emitting layer over and in contact with only a portion of the conduction layer. A first metal contact is in electrical contact with the conduction layer and a second metal contact is in electrical contact with a second contact portion of the light-emitting layer so that a current supplied between the first metal contact and the second metal contact through the inorganic semiconductor causes the light-emitting layer to emit light. A dielectric layer is located over at least a portion of the light-emitting layer and a reflective layer is located over at least a portion of the dielectric layer. The reflective layer encapsulates the light-emitting layer exclusive of the portion of the conduction layer in contact with the light-emitting layer.
