Abstract :
A novel thin-film electroluminescent device having a brightness/voltage characteristic depending strongly on the frequency of the excitation voltage is described. It is essentially a ZnS:Mn thin-film EL device of double-insulating-layer structure with a new dielectric layer of frequency-dependent impedance characteristic as the insulator.
