Abstract
The present invention provides a light emitting device solving weakness caused by bonding between first and second light emitting elements and a method of manufacturing the same. A chip-shaped first light emitting element and a second light emitting element overlapped each other are disposed on a supporting base. Four island-shaped projections are provided on the top face of the supporting base, and support the second light emitting element. The projections are formed by wet-etching or dry-etching the supporting base, and a pad electrode is provided on the top face of the projection. The pad electrode is electrically connected to the second light emitting element and is also electrically connected to a wire.
