Abstract:
A light emitting device includes a light emitting element, a first light transmissive member, and a second light transmissive member. A first lower face of the first light transmissive member is bonded to a light extraction face of the light emitting element and has a first lower face perimeter positioned outside of a light extraction face perimeter of the light extraction face when viewed in a height direction of the light emitting device. A second lower face of the second light transmissive member has a second lower face perimeter that coincides with or is inside of the first upper face perimeter when viewed in the height direction. A second upper face of the second light transmissive member is positioned inside of the first upper face perimeter when viewed in the height direction.
