Patent ID: 8368617

Claim:
A light emitting device comprising: a substrate; a layer having a convexoconcave surface and disposed on the substrate such that the convexoconcave surface faces away from the substrate, the convexoconcave surface having a continuous convexoconcave shape with arcuate convex and concave segments; a first electrode on the convexoconcave surface and conforming thereto so as to have a first electrode surface having the continuous convexoconcave shape and facing away from the substrate; a distance adjustment layer that covers the first electrode, the distance adjustment layer having (i) a first surface that has the continuous convexoconcave shape and contacts the first electrode and (ii) a second surface that is flat and faces away from the first electrode; an organic layer on the distance adjustment layer, the organic layer including a light emitting layer and at least a hole injection layer, the hole injection layer being in contact with the second surface of the distance adjustment layer, and the organic layer being planar over the extent of the first electrode surface; and a second electrode on the organic layer, the second electrode having a second electrode surface that faces the organic layer and is planarized, wherein, the light emitting device has a resonator structure in which light generated in the light emitting layer is resonated between a first end and a second end, the first electrode surface being the first end and the second electrode surface being the second end, and the light being emitted via the second electrode, and an optical distance between the first end and the second end continuously varies according to the continuous convexoconcave shape of the first end.
