Abstract:
A light emitting device includes: a substrate having a concave portion formed on a surface thereof; a light emitting element emitting a first light which is a blue light or a near-ultraviolet light; a resin sheet being a deformable resin sheet formed on the substrate so as to cover the light emitting element; a first transmissive layer formed in a hemispherical shape on the first region of the resin sheet, and transmitting the first light; a color conversion layer including a fluorescent material that converts the first light into a second light of a different wavelength from that of the first light and a transmissive material that transmits the first light, the color conversion layer covering the first transmissive layer in such a manner that an end portion reaches an upper face of the resin sheet; and a second transmissive layer covering the color conversion layer in such a manner that an end portion reaches the upper face of the resin sheet, and transmitting the first light and the second light.
