Abstract:
1. A process for producing an electroluminescent element comprising a patterned electroluminescent layer, said process comprising the steps of: forming an electroluminescent layer on a substrate having at least an electrode layer formed thereon; covering a photoresist layer on said electroluminescent layer; exposing said photoresist layer through a photomask and developing the exposed photoresist layer to pattern the photoresist layer; removing the electroluminescent layer in its areas, which are exposed on the surface of the assembly and are not covered with the photoresist layer as a result of said patterning of the photoresist layer, to pattern said electroluminescent layer; removing the remaining photoresist on the electroluminescent layer covered with said photoresist layer; and further removing the surface layer part of the electroluminescent layer from which said photoresist has been removed.
