Title:
ELECTRON EMITTING ELEMENT, ELECTRON EMITTING DEVICE, SELF-LUMINOUS DEVICE, IMAGE DISPLAY DEVICE, COOLING DEVICE, AND CHARGED DEVICE
Document Type and Number:
Japanese Patent JP2010211967
Kind Code:
A
Abstract:
To provide an electron emitting element in which conductive fine particles are uniformly dispersed on an electron acceleration layer, and electrons can be stably emitted for a long period of time.
A fine particle layer 4 contains conductive fine particles 6 and insulating fine particles 5 with a primary average particle diameter larger than that of the conductive fine particles 6. An average particle diameter of an aggregate of the conductive fine particles 6 in the fine particle layer 4 is 0.35 μm or less.
