ABSTRACT:
A semiconductor light emitting element that includes a substrate having an upper surface, a multi-layered semiconductor stacked structure formed on the upper surface of the substrate. The multi-layered stacked structure emits light when a current is applied and passes through the structure. The element further includes a first electrode disposed on the multi-layered stacked structure and a second electrode disposed aside the multi-layered stacked structure on the upper surface of the substrate. The second electrode constitutes a counter electrode for the first electrode.
