Claim:
1. A light emitting element comprising: a crystal growth substrate formed in a flat shape and that has a translucency; a semiconductor layer that constitutes a light emitting element structure and is formed at a side of a first surface of the crystal growth substrate; irregularities formed on a second surface of the crystal growth substrate, the second surface being an opposite surface of the first surface; and a protective layer that has a translucency and a predetermined hardness and brittleness, and covers the irregularities formed on the second surface of the crystal growth substrate, wherein the protective layer comprises at least one of phosphors and light-scattering material, wherein the protective layer includes a flat surface parallel to the first surface wherein the protective layer comprises a mixed particles of combined body particles, in which mixtures of phosphors and dispersed binders are bound, and the combined body particles are dispersed in a glass, and wherein the dispersed binders are non-glass materials having a translucency and a binding property to the phosphors.
