PURPOSE:To lower the extent of driving voltage as well as to aim at improvement in luminous efficiency by forming a luminous layer, emitting light according to voltage impression, in one side of half-insulative semiconductor substrate, and forming a transparent electrode on this luminous layer, while forming a metal electrode in the other side of the semiconductor substrate. CONSTITUTION:A luminous layer 8, emitting light according to voltage impression, is formed in one side of a half-insulative semiconductor substrate 7, and a transparent conductive material of Au or the like is formed, as a transparent electrode 9, on this luminous layer 8, while another conductive material of In-Ga (5%) or the like, as a metal electrode 10, on an area of the semiconductor substrate 7, thus a film electroluminescent element is produced. The luminous layer 8 reflects a form of the semiconductor substrate 7 so that it comes to such one that is excellent in crystallinity. With this constitution, driving voltage is lowered to some extent and improvement in luminous efficiency is contrivable.
