<p>PURPOSE:To provide a low power consumption electron source and image forming device using an electron emitting element by subjecting the element under the manufacture to a process to reduce the electric resistance of a conductive film, arnd thereby lessening the driving voltage and power consumption of the element CONSTITUTION:An electron emitting element has a conductive film 4 including an electron emission part 3 between two opposing electrodes 5, 6. In manufacturing, the electron emitting element is subjected to a process to reduce the electric resistance of the film 4 formed between the two electrodes 5, 6. The process should preferably be a reductive treatment of the conductive film. Examples are: (1) heating at 100-400 deg.C in a vacuum, (2) heating in a reductive gas atmosphere at a temp. between room temp. and 400 deg.C (the gas of H2, CO, H2S), and (3) heating at 20-100 deg.C in a reductive solution (hydrazine, formic acid, aldehyde, etc.).</p> |
