Abstract

There is provided a process for producing an EL element by photolithography, which process can produce an EL element having improved luminescence efficiency. The production process comprises the steps of removing a photoresist from photoresist layer-covered parts of an electroluminescent layer and cleaning the surface of the electroluminescent layer parts from which the photoresist has been removed.
