ABSTRACT:
An electroluminescence element composed of a substrate, a first electrode, a first insulating layer, a light-emitting layer, a second insulating layer, and a second electrode in this order and a process for producing the same are disclosed, in which the light-emitting layer comprises a chemically stable oxide material containing a plurality of elements, the composition ratio of the elements constituting said oxide material being substantially equal to that of the elements charged, the light-emitting layer is formed by coating a first insulating layer with a sol solution containing a plurality of metal elements at a prescribed composition ratio and heating the coating layer to form an oxide layer.
