Abstract

See full text

A light-emitting device includes: a substrate; and a laminated structure provided at the substrate and having a plurality of columnar parts. The columnar part has: an n-type first semiconductor layer; a p-type second semiconductor layer; a light-emitting layer provided between the first semiconductor layer and the second semiconductor layer; and an electrode provided on a side opposite to a side of the substrate, of the laminated structure. The first semiconductor layer is provided between the light-emitting layer and the substrate. An end part on a side opposite to a side of the substrate, of the light-emitting layer, has a first facet surface. An end part on a side opposite to a side of the substrate, of the second semiconductor layer, has a second facet surface. A relation of θ2≤θ1 is satisfied, where θ1 is a taper angle of the first facet surface, and θ2 is a taper angle of the second facet surface. θ1 is 70° or smaller, and θ2 is 30° or greater.
