摘要： An EL display panel comprising an electroluminescent element made of, for example, a ZnS:Mn layer sandwiched between a pair of dielectric layers exhibits hysteresis properties within light intensity versus applied voltage characteristics. 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 sustaining voltage signal across the electroluminescent element for maintaining the memoried display information. An electron beam is applied to a desired position on the EL display panel through the rear electrode at a time when the sustaining voltage signal bears the zero level in order to erase the memoried information. The memoried display information is electrically read out by detecting a polarization relaxation current which flows through a memoried display position when an electron beam is applied thereto.
