ABSTRACT:
A light emitting diode constituted by a pair of semiconductor layers having a planar P-N junction therebetween, the semiconductor layers having at least one side surface extending transversely across the P-N junction and from which light is emitted in a direction parallel with the plane of the P-N junction, a pair of electrodes on the respective outer surfaces of the pair of semiconductor layers parallel with the plane of the P-N junction plane, at least one of the pair of electrodes covering an area less than the total area of the P-N junction and being located adjacent to the one side surface from which the light is emitted, the remainder of the area of the outer surface of the semiconductor layer not being covered by the electrode, and a light shielding member covering the remainder of the area of the outer surface of the semiconductor layer which is not covered by the one electrode. The light shield member is made of a material identical with that of the one electrode, and is insulated from the one electrode, and the light shielding member and the one electrode are spaced from each other to define a gap therebetween for insulating them from each other.
