Title:
MANUFACTURING METHOD OF ELECTRON EMITTING UNIT, MANUFACTURING METHOD OF COLD CATHODE FIELD ELECTRON EMITTING ELEMENT, AND MANUFACTURING METHOD OF COLD CATHODE FIELD ELECTRON EMITTING DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3828397
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a manufacturing method of a flat type cold cathode field electron emitting element that is capable of forming electron emitting units having uniform and well-controlled convex and concave parts.
SOLUTION: This is a manufacturing method of a cold cathode field electron emitting element that is comprised of a cathode electrode 11, an electron emitting part 15 that is composed of a plurality of electron emitting units 15A formed on the cathode electrode 11, and a gate electrode 13 that is arranged over the electron emitting part 15 and has an opening part 14A. The electron emitting units are formed by (A) a process for forming the base layer 21 on the cathode, (B) a process in which a convex-shape base layer 21 is left on a part of the cathode electrode by electrolyzing the base layer 21, and (C) a process in which an electron emitting layer 22 is formed on the cathode electrode 11 and on the base layer 21.
