ABSTRACT:
An electron-emitting device comprises a pair of electrodes and an electroconductive thin film therebetween having an electron-emitting region. The electroconductive thin film is coated with an additional film at the electron-emitting region to provide an additional resistance within a range from 500 .OMEGA. to 100 k.OMEGA..
