Abstract: The inventive thin-film DC-driving electroluminescent device (ELD) is characterized by the thin-film current control layer which is inserted between a thin film phosphor layer and metal electrodes. This kind of ELD has the advantages of having a lower operation voltage than that of the conventional thin-film AC ELD and a higher resolution than that of the conventional thin-film/powder hybrid DC ELD. The thin-film current control layer acts as an energy barrier layer which supplies energetic electrons into said phosphor layer by a field-assistant injection of electron, and a current-limiting layer which prevents an electric field breakdown of said electroluminescent device caused by an excess current flow. The current control layer is embodied with a multilayered thin film laminated by an alternate deposition of metal oxides. In another embodiment, the current control layer consists of both an energy barrier layer and a current-limiting layer, separately formed.
