Abstract: A method of manufacturing a light emitting device includes: mounting a light emitting element in a package in which a recess is defined, the light emitting element being mounted on a bottom surface defining the recess; forming a first reflecting layer by covering lateral surfaces defining the recess with a first resin containing a first reflecting material; forming a second reflecting layer covering the bottom surface defining the recess, wherein the step of forming the second reflecting layer comprises settling the second reflecting material in the second resin by a centrifugal force so as to form (i) a layer containing a second reflecting material on the bottom surface defining the recess, and (ii) a light-transmissive layer above the layer containing the second reflecting material; and disposing a phosphor-containing layer on the second reflecting layer and the light emitting element, the phosphor-containing layer comprising a third resin that contains a phosphor.

Abstract: A light emitting device includes a substrate, a light emitting element mounted on the substrate, a light transmissive member placed on an upper surface of the light emitting element, and a sealing member which seals the light emitting element and the light transmissive member. The light transmissive member is a plate-shaped member not containing a phosphor and is larger than the light emitting element when viewed from above. The sealing member includes a first sealing member which is formed of a light reflecting member for reflecting light emitted from the light emitting element and covers side surfaces of the light emitting element, and a second sealing member which contains a phosphor for converting the light emitted from the light emitting element into light having wavelength different from wavelength of the light emitted from the light emitting element and covers at least an upper surface of the light transmissive member.
