ABSTRACT:
An electroluminescent display device with decreased voltage requirements comprises a substrate having a major surface, a first electrode over the major surface, a light-emitting film over the first electrode, and a second electrode over the light-emitting film. At least one insulating film is disposed in contact with a major surface of the light-emitting film, which insulating film has a columnar crystal structure oriented parallel to an electric field formed between the two electrodes.
