ABSTRACT:
A method of manufacturing an electron-emitting device includes providing a pair of electrodes and an electroconductive thin film arranged between the electrodes. The method also includes a step of forming an electron-emitting region in the electroconductive film by the steps of partially modifying the composition of the electroconductive thin film with a chemical change to make a region of the electroconductive thin film have a higher resistivity than a resistivity in other regions, and causing an electric current to run through the electroconductive thin film to form the electron-emitting region in the region having the higher resistivity.
