Claim:
1. An electroluminescent substrate comprising: a gate insulating film; a transistor; an electroluminescent element; a capacitor section; and a protective layer, a semiconductor layer of the transistor, a lower part electrode of the electroluminescent element, and an upper part electrode of the capacitor section being provided on the gate insulating film, a source electrode of the transistor contacts and overlaps an interface between the semiconductor layer and the lower part electrode, and the protective layer being provided over the semiconductor layer, the lower part electrode, and the upper part electrode, the protective layer having an opening through which the lower part electrode and the upper part electrode are exposed, the semiconductor layer being an oxide semiconductor layer, and each of the lower part electrode and the upper part electrode being a reduction electrode which has been made by reducing the oxide semiconductor layer provided on the gate insulating film.
