An electroluminescent device includes at least first and second radiation emitter devices arranged on a common substrate. Each radiation emitter devise includes a first active layer and a second layer of organic material for generating the radiation, respectively. This device includes isolation means of dielectric material which are at least partially interposed between the first and second active layers to electrically isolate the first layer from the second active layer.
