发明名称 LIGHT EMITTING DEVICE
摘要 A light emitting device 1 includes a wiring substrate 4 on which a light emitting element 2 is mounted, a sealing section 5 containing a phosphor and sealing the light emitting element 2, a light diffusion section 7 provided on the sealing section 5 and containing particles for diffusing light emitted from the light emitting element 2, and a light reflection section 6 provided so as to cover part of the sealing section 5 other than a top surface of the sealing section 5 and reflecting light emitted from the light emitting element 2. In the light diffusion section 7, silicone dioxide which is a diffusing material is contained in a transparent medium which is a base material. In the light reflection section 6, titanium dioxide which is a reflective material is contained in a transparent medium which is a base material.
