Abstract
A method of manufacturing a light emitting device includes: bonding a wavelength conversion sheet containing phosphor particles onto upper surfaces of light emitting elements mounted on a substrate; dividing the wavelength conversion sheet into a plurality of wavelength conversion members, each corresponding to one of the light emitting elements, by cutting from an upper surface of the wavelength conversion sheet; forming light reflecting members between adjacent ones of the wavelength conversion members to reflect light emitted from the light emitting elements; and machining an upper surface of a collective body including the wavelength conversion members and the light reflecting members into a curved surface having a concave shape.
