Abstract: A light emitting device includes: a package having an upper surface defining a recess; a light emitting element and a protection device respectively disposed on a bottom surface of the recess; a first reflecting layer covering a lateral surface of the recess; and a second reflecting layer covering the bottom surface of the recess. The first reflecting layer is apart from the light emitting element and covers the protection device. The second reflecting layer contacts with a lower portion of a lateral surface of the light emitting element. An upper surface of the light emitting element and an upper portion of the lateral surface of the light emitting element are exposed from the second reflecting layer.
