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.
