ABSTRACT:
An electroluminescent device of compound semiconductor includes a compound semiconductor substrate having at least one through-hole, an electroluminescent part consisting of a plurality of epitaxial compound semiconductor layers formed on the substrate, and at least a pair of electrodes having external leads in which one electrode is connected to the uppermost layer of the electroluminescent part and another electrode is directly connected to the lowest layer of the electroluminescent part through the through-hole of the substrate. Thereby, a voltage from an external source is enabled to be directly applied to the electroluminescent part.
