Abstract
Electron excited luminous element capable of ensuring satisfactory emission characteristics of emitters for an extended period of time. A hydrophobic insulating film is formed on a glass anode substrate so as to cover an exposed portion thereof between anode electrodes. This keeps the glass anode substrate from being directly attacked by electrons, to thereby prevent decomposition of water and the like contained in a surface of the glass, resulting in oxygen which causes deterioration in emission characteristics of emitter cones being kept from being released from the glass.
