Abstract

A light emitting device includes a substrate, a light emitting unit disposed on the substrate, a metallic electrode unit, a metallic adhesion layer disposed on the first and second electrodes of the electrode unit, and a protective layer disposed on the adhesion layer. The first electrode is disposed on a portion of a first-type semiconductor layer of the light emitting unit. The second electrode is disposed on a second-type semiconductor layer of the light emitting unit disposed on a separated portion of the first-type semiconductor layer. The first and second electrodes are partially exposed by the protective layer and the adhesion layer that is partially exposed by the protective layer. A production method for the light emitting device is also disclosed.
