Abstract
A light emitting device includes a light emitting element, a first light transmissive member, a second light transmissive member, and a light reflective member. The first light transmissive member contains a first phosphor. The first light transmissive member is in contact with an upper surface of the light emitting element, and has an area smaller than the light emitting element in a plan view. The second light transmissive member contains a second phosphor. The second light transmissive member covers lateral surfaces of the first light transmissive member and a part of the upper surface of the light emitting element that is exposed from the first light transmissive member, with an upper surface of the first light transmissive member being not covered by the second light transmissive member. The light reflective member covers lateral surfaces of the second light transmissive member and lateral surfaces of the light emitting element.
