1. A semiconductor light emitting element comprising:

  • a light emitting layer for emitting light of a wavelength λ

    by current injection; and

    a GaP substrate transparent to light of the wavelength λ and

    having;

    a first surface on which the light emitting layer is formed;

    a second surface opposed to the first surface and having an area smaller than the first surface; and

    side surfaces individually being aslant to become narrower toward the second surface and permitting part of light from the light emitting layer to be extracted externally therethrough, said side surfaces having a plurality of depressions and protrusions along outer surfaces thereof.
