<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a cold cathode display device capable of securing uniformity in the surface of the aperture diameter of the aperture parts which are passing holes of electrons. <P>SOLUTION: A cathode electrode 5 is arranged on a substrate 4, and a sacrifice layer 15 is formed at a prescribed location (location where an electron releasing material 13 is formed later) of the cathode electrode 5. Then, an insulating membrane 6 and a gate electrode 7 are formed so as to cover the sacrifice layer 15, and then, by removing the sacrifice layer 15, a through hole 12 is formed on the insulating membrane 6 and also the aperture part 8 is formed on the gate electrode 7. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
