Light emitting device having a backside electrode portion and same thickness protrusion and method of manufacturing the same
Abstract:
A light emitting device capable of emitting an excellent mixed color light, and a light emitting device capable of enhancing the concentration of mixed light or the directivity of emission is provided. The light emitting device comprises a light emitting element and a package. The package includes at least two recesses each having a bottom surface for mounting a light emitting element thereon and a side surface extending from the bottom surface, wherein each recess has, in a vertical cross section of the recess, a vertical line passing through the center of the bottom surface of the recess which is different than a vertical line passing through the intersection of a first straight line extending along an inclined edge of the recess and a second straight line extending along an inclined edge on another side of the recess.
