Patent Searching and Data


Title:
ELECTRON EMISSION ELEMENT, ELECTRON EMISSION DEVICE, SELF-LUMINOUS DEVICE, IMAGE DISPLAY DEVICE, AIR BLOWING DEVICE, COOLING DEVICE, ELECTROSTATIC CHARGE DEVICE, IMAGE FORMING DEVICE, ELECTRON BEAM CURING DEVICE, AND METHOD OF MANUFACTURING THE ELECTRON EMISSION ELEMENT
Document Type and Number:
Japanese Patent JP2011175843
Kind Code:
A
Abstract:

To provide an electron emission element to which proper voltage is applied to produce a sufficient amount of electron emissions.

The electron emission element is provided which includes a first electrode, an insulation fine particle layer formed on the first electrode and consisting of insulation fine particles, and a second electrode formed on the insulation fine particle layer. In the surface of the insulation fine particle layer at the side of the second electrode, recessed portions are formed whose depths are each smaller than the layer thickness of the insulation fine particle layer. When voltage is applied between the first electrode and the second electrode, electrons supplied from the first electrode are accelerated in the insulation fine particle layer and then emitted from the second electrode.
