Abstract: A light emitting device includes a package having an upper surface and an upward-opening recess defined in a portion of the upper surface, at least one light-emitting element in the recess, a light-transmissive member covering the opening of the recess, and an antireflection film on a lower surface of the light-transmissive member, the antireflection film located between the lower surface of the light-transmissive member and an upper surface of the package at a location where a portion of the lower surface of the light-transmissive member is bonded to the upper surface of the package via the antireflection film. A coating film is disposed on at least a portion of an outer surfaces of the light emitting device, the portion including a region where the antireflection film located between the lower surface of the light-transmissive member and the upper surface of the package is exposed.

Abstract: A light emitting device includes: a base having an upper face; a light emitting element mounted on the upper face of the base; one or more bonding members disposed on the upper face of the base outward of the light emitting element; a light transmissive member bonded to a portion of the upper face of the base by the one or more bonding members; and a protective film that continuously covers the light emitting element, the upper face of the base, lateral faces of the one or more bonding members, and a lower face of the light transmissive member. A gap is located between the upper face of the base and the lower face of the light transmissive member and configured to allow a space in which the light emitting element is mounted to communicate with an outside of the light emitting device, wherein the gap is defined by the upper face of the base, the lower face of the light transmissive member, and the one or more bonding members.
