Abstract
A light emitting device includes first and second light emitting elements, first and second color conversion material layers, a support member and a light reflective member. The first color conversion material layer has a first color conversion surface facing a first light extraction surface of the first light emitting element. The second color conversion material layer has a second color conversion surface facing a second light extraction surface of the second light emitting element. The support member supports the first and second color conversion material layers. The light reflective member covers a first side surface of the first light emitting element and a second side surface of the second light emitting element. At least a part of an upper surface of the light reflective member is positioned closer to the support member than the first color conversion material layer and the second color conversion material layer.
