FIELD EMISSION COLD CATHODE ELECTRON DEVICE

Title:

FIELD EMISSION COLD CATHODE ELECTRON DEVICE

Document Type and Number:

Japanese Patent JP3343060

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To prevent the generation of flickers of a fluorescent material, emitter damages, etc., and to prolong life and improve reliability.
SOLUTION: This field emission cold cathode electron device comprises a field emission cold cathode 10 formed with a gate 23 via an SiO2 film 22 on an Si substrate 21 and an emitter 26 which emits an electron by a tunnel effect in an opening removed of the gate 23, and an anode part 30 formed with an anode 32 on a glass substrate 31, and a fluorescent material 33 oppositely arranged to the field emitting cold cathode 10 on its top. On a part removed of the gate 23 on the SiO2 film 22 of the field emission cold cathode 10, a fine particle adsorption electrode 28 made of Ga is formed.
