Patent ID: 8278667

Claim:
A light-emitting element comprising: a semiconductor layer; a gold electrode layer that is formed on a part of the semiconductor layer and electrically connected to the semiconductor layer, the gold electrode layer being made of metal including gold; an insulator film that covers the semiconductor layer and has a contact opening corresponding to the gold electrode layer; a barrier metal layer that covers an upper face of the gold electrode layer and the insulator film in a vicinity of the contact opening; and an aluminum wiring layer that is formed on the barrier metal layer and electrically connected to the barrier metal layer, that extends on the insulator film in a direction departing from the vicinity, and that is made of metal including aluminum, wherein a lower surface of the aluminum wiring layer is in contact with the barrier metal pattern in the contact opening and in the vicinity of the contact opening, and extends in the direction in a state of contacting with the insulator film.
