<p><P>PROBLEM TO BE SOLVED: To reduce the number of production processes and cost when producing resistance films for prevention of charge-up, limitation of current to electron emission layers, suppression of electrode migration, and protection of electrodes. <P>SOLUTION: The cold-cathode electron source having a cathode electrode with an electron emission layer 6 and a gate electrode separately disposed with an exposed insulating area therebetween includes four areas: an exposed insulating area not covered with the electrodes, a boundary area between the cathode electrode and the electron emission layer, an exposed electrode area, and an exposed area on the top of the electron emission layer, wherein a single continuous high-resistance film is placed on at least two of the four areas. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
