Abstract
Provided is a light emitting device having a phosphor layer on a surface of a semiconductor light emitting element and reducing unevenness in light distribution color, and a method of manufacturing the same. A light emitting deviceincludes a light emitting elementwith a supporting body which is composed of a semiconductor light emitting elementand a supporting body, and a phosphor layerwhich continuously covers an upper surface and side surfaces of the semiconductor light emitting element, and side surfaces of the supporting body. The phosphor layeris configured such that at least a lower portion of the side surface of the supporting bodyis thinner than the upper surface and the side surface of the semiconductor light emitting element. Such a configuration of the phosphor layer can be formed by applying a spray-coating of a slurry containing phosphor particles and a thermosetting resin in a solvent on the semiconductor light emitting elementside of the light emitting elementwhich has the supporting body.
