Abstract
In a method of manufacturing an electron-emitting device, an electroconductive film formed on a substrate is subjected to a clean processing to remove a foreign matter from the electroconductive film, and thereafter, energization is conducted on the electroconductive film, to form an electron-emitting region. Accordingly, there is provided an electron-emitting device which avoids a formation defect of the electron-emitting region due to the existence of the foreign matter and which has satisfactory characteristics without fluctuation.
