SURFACE CONDUCTIVE ELECTRON EMITTING ELEMENT AND IMAGE DISPLAY DEVICE USING IT

摘要

PURPOSE:To eliminate dispersion in the characteristics of electron emitting element from to piece which has a plurality of electron emission parts, enhance the yield of elements from production line, and prolong the lifetime of the element by changing over that part of each electron emitting element which concerns the electron emission after the element is forned. CONSTITUTION:A plurality of electron emission parts 5 in serial connection electrically are provided between a pair of electrodes 1, 2. An electtroconductive member 8 melting eith heat is furnished in the neighborhood of each electron emission part 5.
