Title:
COLD-CATHODE ELECTRON SOURCE, ITS MANUFACTURING METHOD, AND LIGHT-EMITTING ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2008/069243
Kind Code:
A1
Abstract:
A cold-cathode electron source having a cathode and an electron-emitting part
provided on the cathode electrode and using an activated metal oxide. The activation
is conducted by raising by tape peeling, by applying a laser beam, by applying
high-electric field, or the like. If laser application or high electric field
application is used, an emission phenomenon can be brought about even at a low
applied voltage even if a nonconductive metal oxide is used. A cold-cathode electron
source in which metal oxide more inexpensive than carbon nanotube is used as the
emitter material can be provided.
