Abstract
A light emitting device includes a conductive substrate having a first substrate surface and comprising a conductive material, a protrusion formed on the conductive substrate, wherein the protrusion is defined in part by a first protrusion surface that is not parallel to the first substrate surface, and light emission layers disposed over the first protrusion surface. The light emission layers can emit light when an electric field is applied across the light emission layers.
