Abstract
A light emitting element includes: a substrate; a first conductive type semiconductor layer stacked on the substrate; a light emitting layer stacked on the first conductive type semiconductor layer; a second conductive type semiconductor layer stacked on the light emitting layer; an ITO layer stacked on the second conductive type semiconductor layer; and a reflective layer stacked on the ITO layer. The substrate is transparent to an emission wavelength of the light emitting layer, and the reflective layer includes a Ti-containing first layer stacked on the ITO layer to make contact with the ITO layer and an Al-containing second layer stacked on the first layer in an opposite side to the ITO layer.
