摘要：
An electron-emitting device comprises a pair of oppositely disposed device electrodes and an electroconductive film electrically connecting the device electrodes and having an electron-emitting region formed as part thereof. The electroconductive film is partly or entirely covered by a metal oxide coat containing as principal ingredient with a melting point higher than that of the material of principal ingredient of the electroconductive film. The electroconductive film has also a deposited layer comprising carbon, a carbon compound or a mixture thereof.
