Light emitting device and method of manufacturing light emitting device
A light emitting device includes a light emitting element, a wavelength conversion member, a reflecting member and a covering member. The light emitting element has a top surface and lateral surfaces. The wavelength conversion member has a top surface, a bottom surface, and lateral surfaces, with the bottom surface of the wavelength conversion member facing the top surface of the light emitting element. The reflecting member surrounds the lateral surfaces of the light emitting element and the lateral surfaces of the wavelength conversion member. The reflecting member has a top surface. The covering member covers the top surface of the wavelength conversion member and the top surface of the reflecting member. The covering member contains a pigment or a dye so that a body color of the covering member is the same or a similar color as a body color of the wavelength conversion member.
