Light emitting element and light emitting device using the same

Abstract

A light emitting element includes a semiconductor stacked layer body having an n-type semiconductor layer, an active layer, and a p-type semiconductor layer in this order, and a plurality of exposed portions defined at an upper surface side of the semiconductor stacked layer body, the plurality of exposed portions respectively exposing a part of the n-type semiconductor layer, a p-side electrode arranged in a first region and electrically connected with an upper surface of the p-type semiconductor layer and, arranged at one corner above the p-type semiconductor layer in a plan view, and an n-side electrode electrically integrally connected to the plurality of exposed portions and arranged in a different region in a plan view. In a plan view, the semiconductor stacked layer body has a rectangular shape and the plurality of exposed portions includes, a plurality of first exposed portions arranged at substantially equal intervals along a side of the semiconductor stacked layer body and a plurality of second exposed portions arranged closer to the p-side electrode than the first exposed portions are to the p-side electrode. The plurality of second exposed portions include at least one second exposed portion which has a shortest distance to the first exposed portions, the shortest distance to the first exposed portions being longer than a shortest distance among the first exposed portions. The at least one second exposed portion also has a shortest distance to the p-side electrode shorter than the shortest distance among the first exposed portions.
