Abstract

A light-emitting device (100) includes: a semiconductor layered structure (10); an upper electrode (11) disposed on a portion of an upper surface of the semiconductor layered structure (10); a lower electrode (12) disposed on a lower surface of the semiconductor layered structure (10) in a region spaced from a region directly under the upper electrode (11), the lower electrode (12) being reflective; and a protective film (13) disposed continuously on a surface of the upper electrode (11) and on the upper surface of the semiconductor layered structure (10). A thickness of a first portion of the protective film (13), which is disposed at least in a region (12R) directly above the lower electrode (12), is smaller than a thickness of a second portion of the protective film (13), which is disposed continuously on the surface of the upper electrode (11) and on a portion of the upper surface of the semiconductor layered structure (10) adjacent to the portion on which the upper electrode (11) is disposed.
