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