This abstract first appeared for US patent application 18827150 titled 'LIGHT EMITTING ELEMENT

==Original Abstract Submitted==

A light emitting element includes: a semiconductor structure including: a first semiconductor layer that has: a first face that has a peripheral region, and a central region surrounded by the peripheral region in a plan view, wherein a surface roughness of the central region is higher than a surface roughness of the peripheral region, and a second face that opposes the first face and has a first region and a second region, an active layer disposed on the first region, and a second semiconductor layer disposed on the active layer; a first electrode disposed on the second region and electrically connected to the first semiconductor layer; a second electrode disposed on the second semiconductor layer and electrically connected to the second semiconductor layer; a first reflecting film disposed only on the peripheral region among the surfaces of the semiconductor structure; and a first protective film disposed on the central region.
