ABSTRACT:
A process for producing an electroluminescent device comprises providing in a film forming space for forming an electroluminescent film a substrate having an electrode formed on the surface thereof, said electrtode optionally having a first insulating layer formed thereon, introducing into said film forming space the compounds (A), (B) and (C) represented by the general formulae (A), (B) and (C) shown below and a gaseous halogenic oxidizing agent capable of chemically reacting with at least one of said compounds (A), (B) and (C), respectively, to thereby form an electroluminescent film on said electrode of said substrate, and if desired forming a second insulating layer and electrode in succession thereon:
