Abstract:
A light emitting device includes a mounting board, a light emitting element, first and second light reflecting members, a light transmissive member and a sealing member. The first light reflecting member surrounds a lateral surface of the light emitting element while a top surface of the light emitting element is exposed from the first light reflecting member. The second light reflecting member surrounds an outer periphery of the light emitting element in a plan view. The second light reflecting member is in contact with the first light reflecting member with at least a part of the second light reflecting member being positioned higher than the first light reflecting member. The light transmissive member is disposed inside the second light reflecting member. The light transmissive member includes a wavelength conversion substance. The sealing member covers the first and second light reflecting members and the light transmissive member.
