Summary:An electron-emitting device comprises an electroconductive film including an electron-emitting region and a pair of electrodes for applying a voltage to the electroconductive film. The electron-emitting region is formed by applying a film of organic substance to the electroconductive film, carbonizing the organic substance by electrically energizing the electroconductive film, and forming a fissure or fissures in the electroconductive film prior to the carbonization. The electron-emitting device constitutes an electron source having a plurality of electron-emitting devices, and further an image-forming device comprising an electron source and an image-forming member arranged in an envelope.
