Abstract

A light emitting device including a mounting board, one or more light emitting elements, a light transmissive member, and a light reflective member. The light emitting element(s) are mounted on the mounting board, and each include an upper surface. The light transmissive member is bonded to the upper surface of each of the light emitting element(s). The light transmissive member has an upper surface and a lower surface, and allows light from the light emitting element(s) 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. The light reflective member covers surfaces of the light transmissive member and lateral surfaces of the light emitting element(s) and exposes the upper surface of the light transmissive member. At least a first portion of the mounting board is exposed from the light reflective member in a plan view.
