Patent ID: 8867585

Claim:
A device comprising: a first layer selected from a glass substrate, a quartz substrate, a plastic substrate, or a resin film; a light emitting element over the first layer; and a light-transmitting second layer covering the light emitting element, the light-transmitting second layer being selected from a glass substrate, a quartz substrate, or a plastic substrate, wherein the light-transmitting second layer has a curved convex portion which overlaps with the light emitting element and a flat portion around the curved convex portion, wherein the light emitting element comprises a first electrode and a second electrode with an electroluminescent layer sandwiched therebetween, wherein the curved convex portion and the flat portion each overlap with the first electrode and the electroluminescent layer, wherein the light-transmitting second layer is in direct contact with a top surface of the electroluminescent layer, and wherein the second electrode is confined in a region which overlaps with the curved convex portion.
