ABSTRACT:
An EL display panel comprises an electroluminescent element made of, for example, a ZnS:Mn layer sandwiched between a pair of dielectric layers. A front electrode is formed on one of the dielectric layers, and a rear electrode is formed on the other dielectric layer in order to apply a voltage signal across the electroluminescent element. An electron beam is applied to the electroluminescent element through the rear electrode to provide the electroluminescence at the position to which the electron beam is applied. A desired pattern is displayed on the EL display panel by properly controlling the application of the electron beam.
