Abstract

A light emitting device includes a light emitting element and a luminescent color conversion layer covering a light emitting surface of the light emitting element. The luminescent color conversion layer includes a transparent synthetic resin material and integrated particles provided inside the transparent synthetic resin material, each of the integrated particles being a mixture of phosphors and a dispersively binding material that are bonded to each other. The dispersively binding material has transparency and bondability to the phosphors. The luminescent color conversion layer is arranged such that primary light and secondary light are mixed to generate a mixed color light and such that the mixed-color light is emitted outside from the luminescent color conversion layer, the primary light being excitation light emitted by the light emitting element, and the secondary light being a portion of the primary light that has been is color-converted by an excitation of the phosphors.
