Abstract:
A method for producing an electron-emitting device, said method comprising the steps of:a step of preparing a sodium-containing substrate having a first principal surface and a second principal surface opposed to each other;a step of forming an electroconductive film on the first principal surface;an electric field application step of applying an electric field to cause a potential of the first principal surface to become higher than a potential of the second principal surface, to cause at least one sodium ion existing in a side of the first principal surface to move to a side of the second principal surface, thereby reducing a concentration of sodium ions in the side of the first principal surface and minimizing an influence of sodium ions during an energization step of energizing said electroconductive film; andan energization step of energizing said electroconductive film after the electric field application step.
