A thin film EL display device comprising a transparent conductive film formed on a transparent substrate, a first EL emission film formed on the transparent conductive film directly or by way of an insulation film, at least one set of voltage applying electrodes not connected electrically with each other and formed on the EL emission film directly or by way of an insulation film, a second EL emission film formed on the voltage applying electrode directly or by way of an insulation film and a conductive film formed on the second EL emission film directly or by way of an insulation film. Multi-color display is possible by the combination of emission color of the first EL emission film and/or the emission color of the second emission film. Easy lead out for the electrode is possible and pattern shape and width can optionally be set not restricted to the material for the transparent conductive film.
