Light Emitting Element and Illumination Device

摘要

Provided is a light emitting element capable of improving light extraction efficiency and suppressing the nonuniformity of emission intensity distribution over the entire surface of a light extraction surface. The light emitting element is provided with a semiconductor multilayer body having an n-type semiconductor layer and an emission layer and a p-type semiconductor layer, and an electrode pad connected to the p-type semiconductor layer. The semiconductor multilayer body has a large number of projections on one main surface thereof through which the light from the emission layer is emitted. The main surface of the semiconductor multilayer body has a first region located in the vicinity of the electrode pad, and a second region being further separated from the electrode pad than the first region. The interval between the projections in the second region is smaller than that in the first region.
