Abstract
A light emitting device includes a light-transmissive member including a first surface, a second surface opposite to the first surface, and third surfaces connected to the first surface and the second surface. A phosphor layer faces the second surface of the light-transmissive member. A reflective member faces side surfaces of the phosphor layer and the third surfaces of the light-transmissive member. The light-emitting element has a top surface facing the phosphor layer, a bottom surface opposite to the top surface, and side surfaces connecting the top surface and the bottom surface. The phosphor layer has a bonding surface facing the light emitting element. A first dielectric multilayer film is arranged on at least one of side surfaces of the light-emitting element without being provided on the bonding surface of the phosphor layer.
