1. A light emitting device comprising:
a mounting board;
one or more light emitting elements mounted on the mounting board, the one or more light emitting elements each including an upper surface as a light extraction surface;
a light transmissive member bonded to the upper surface of each of the one or more light emitting elements, the light transmissive member having an upper surface and a lower surface and a lateral surface, and allowing light from the one or more light emitting elements to be incident on the lower surface of the light transmissive member and to be output from the upper surface of the light transmissive member; and
a light reflective member covering surfaces of the light transmissive member and lateral surfaces of the one or more light emitting elements so as to expose the upper surface of the light transmissive member,
wherein at least a first portion of the mounting board is exposed from the light reflective member in a plan view,
wherein, in the plan view, the light transmissive member further has a second upper surface surrounding the upper surface of the light transmissive member, and the lower surface is opposite the upper surface of the light transmissive member and the second upper surface,
wherein, in the plan view, the lower surface of the light transmissive member encompasses the one or more light emitting elements, and the second upper surface of the light transmissive member overlaps the upper surface of each of the one or more light emitting elements,
wherein the lateral surface of the light transmissive member has a curved surface, and
wherein the second upper surface of the light transmissive member has a portion parallel to an upper surface of the mounting board without an intervening light emitting element of the one or more light emitting elements in the plan view.
