Abstract
A light emitting element and a light emitting device for which light extraction efficiency is enhanced are provided. A light emitting element 10 includes a substrate 1 having light transmittance, a semiconductor layer 2 in which an n-type layer 2a, an active layer 2b, and a p-type layer 2c are stacked, a reflective electrode 3 stacked on the semiconductor layer 2 and configured to reflect light emitted from the active layer 2b, toward the substrate 1, a p-side pad electrode 4 stacked on the reflective electrode 3, an insulating film 6 covering a side surface of the semiconductor layer 2 and having light transmittance, a reflective film 7 stacked on the insulating film 6 and having light reflectivity, and an n-side electrode 5 provided on the substrate 1.
Claims12
A light emitting element, comprising:
- a substrate having light transmittance;
- a semiconductor layer in which an n-type layer, an active layer, and a p-type layer are stacked on the substrate;
- a reflective electrode stacked on the semiconductor layer and configured to reflect light emitted from the active layer, toward the substrate;
- a p-side pad electrode stacked on the reflective electrode;
- an insulating film covering a side surface of the semiconductor layer and having light transmittance;
- and
- a reflective film stacked on the insulating film and having light reflectivity, wherein:
- the p-side pad electrode and the reflective film are integrally formed,
- the reflective film covers the side surface of the semiconductor layer with the insulating film being interposed therebetween, and
- no insulating film is formed on an outer surface of the reflective film.
