Abstract
A method for manufacturing a light-emitting device including a light-emitting element and a quantum dot configured to convert light emitted by the light-emitting element includes: preparing a base and a light-emitting element disposed on the base; forming a light reflective member surrounding the light-emitting element and including an inner surface and a top surface; forming a first barrier layer continuously covering a surface of the light-emitting element and the inner surface and the top surface of the light reflective member; forming a wavelength conversion member including the quantum dot in a region surrounded by the inner surface of the light reflective member, the light-emitting element being embedded in the wavelength conversion member; and covering, with a second barrier layer, a top surface of the wavelength conversion member and at least a portion of the first barrier layer on the top surface of the light reflective member.
