According to an aspect of the invention, a light-emitting element includes a semiconductor layer, a gold electrode layer, an insulator, a barrier metal layer, and an aluminum wiring layer. The gold electrode layer is formed on a part of the semiconductor layer and is electrically connected to the semiconductor layer. The gold electrode layer being made of metal including gold. The insulator film covers the semiconductor layer and has a contact opening corresponding to the gold electrode layer. The barrier metal layer covers a an upper face of the gold electrode layer and the insulator film in a vicinity of the contact opening. The aluminum wiring layer is formed on the barrier metal layer and electrically connected to the barrier metal layer.
