ABSTRACT:
An electroluminescent display device comprising an electroluminescent emitting layer including zinc oxide containing a luminescent active material, an insulating layer formed on one surface of the electroluminescent emitting layer and a pair of energizing means for applying signal voltages corresponding to an information to be displayed to a multilayer assembly including the said two layers, characterized in that a plurality of semiconductor layers each containing at least one chemical compound selected from the group consisting of chemical compounds of the II-VI groups and tin oxide are arranged as one of the energizing means arranged on the side of the electroluminescent emitting layer or between the energizing means arranged on the side of the electroluminescent emitting layer and the electroluminescent emitting layer. This device features that it requires only a reduced drive voltage for image displaying purposes and ensures an increased luminescent brightness.
