Abstract
A light-emitting element includes a semiconductor layered body comprising: an n-type semiconductor layer, and p-type semiconductor layer; an insulating film disposed on the semiconductor layered body and defining at least one p-side opening above the p-type semiconductor layer and a plurality of n-side openings exposing the n-type semiconductor layer; an n-side electrode disposed on the insulating film and comprising a plurality of first n-contact portions each electrically connected to the n-type semiconductor layer through one of the plurality of n-side openings; a p-side electrode electrically connected to the p-type semiconductor layer through the at least one p-side opening; a p-side post electrode disposed on the p-side electrode; and an n-side post electrode disposed on the n-side electrode. A total area of one or more first n-contact portions located on the second side is smaller than a total area of one or more first n-contact portion located on the first side.
