Abstract
A metal layer , a light emitting layer section and a first electrode are formed in the order on a first main surface side of a conductive substrate and a current is supplied to the light emitting layer section through the first electrode and the conductive substrate . By using reflection on the metal layer , not only can good external quantum efficiency be realized, but electrodes or terminals can also be formed on both sides of the light emitting element. Thus, provided is a light emitting element excellent in external quantum efficiency thereof and in addition, not only simple in structure of a terminal lead thereof but excellent in convenience.
