Abstract
A light emitting element having a light emitting element portion formed of a group III nitride-based compound semiconductor and having a layer to emit light. The light emitting element portion is formed by lifting off a substrate by wet etching after the light emitting element portion is grown on the substrate. The light emitting element portion has a lift-off surface that is kept substantially intact as it is formed in growing the light emitting element portion on the substrate.
