<p>PURPOSE: To provide an electron emitting element to perform light emission and electron emission with a low power consumption which is favorable for embodying an image forming device producing a light and high-grade image by equipping the electron emitting element with a conductive film having an electron emission part between electrodes, and locating the conductive film in a specific position. CONSTITUTION: An electron emitting element has a conductive film 3 having an electron emission part 2 between electrodes 4, 5, wherein the film 3 having electron emission part 2 which is favorably a gap formed in the film 3 is located on a light emitting body 6. The light emitting body 6 should preferably be such one as energized by a low-speed electron beam and emitting light. The intended image forming device is composed of a plurality of such elements, a modulating means to modulate the electron beam emitted by each element in conformity to the information signal, and an image forming member (phosphor, etc.) to form images by means of irradiation with electron beam.</p> |
