Title:
ELECTRON EMITTING ELEMENT, ELECTRON EMITTING DEVICE, SELF LIGHT-EMITTING DEVICE, IMAGE DISPLAY, BLOWER, COOLING DEVICE, ELECTRICALLY-CHARGED DEVICE, IMAGE FORMING DEVICE, ELECTRON-BEAM CURING DEVICE, AND METHOD FOR MANUFACTURING ELECTRON EMITTING ELEMENT
Document Type and Number:
Japanese Patent JP2011003521
Kind Code:
A
Abstract:
To provide an electron emitting element which hardly generates insulation breakdown and is produced easily at low cost and emits stably a suitable amount of electrons.
The electron emitting element 1 includes insulator fine particles 5 between an electrode base board 2 and a thin-film electrode 3, and has an electron acceleration layer 4 excluding conductive fine particles. The electron emitting element 1 emits an electron from the thin-film electrode 3 by accelerating the electron in the electron acceleration layer 4 when applying voltage between the electrode base board 2 and the thin-film electrode 3.
