Title:
ELECTRON EMISSION DEVICE AND FIELD EMISSION DISPLAY
Document Type and Number:
WIPO Patent Application WO/2002/061789
Kind Code:
A1
Abstract:
Low-cost electron emission device and field emission display using a cold cathode that is high in electron beam utilization efficiency and can restrict the spreading of an electron beam. A configuration is built such that an electric field strength at or near a gate electrode acting as an electron emission quantity control unit is made different between the center and the periphery of a 1-pixel (or 1-sub-pixel) in-plane under a condition, Ea $m(G) Eg, so that the spreading of an electron beam can be restricted, whereby a device using a field emission electron source array enabling a low voltage and a high emission current density can be provided at low costs.
