Title:

PASTE FOR ELECTRON EMISSION SOURCE, ELECTRON EMISSION SOURCE USING SAME, ELECTRON-EMITTING ELEMENT, AND METHOD FOR PRODUCING EACH

Document Type and Number:

WIPO Patent Application WO/2011/093204

Kind Code:

A1

Abstract:

By means of a paste that is for an electron emission source and that contains a carbon material for an electron emission source, phosphate glass, and conductive particles having an average particle size of 0.1-1.0 μm, the phosphate glass containing 25-70 mol% of a P2O5 component, and the conductive particles being particles containing a conductive oxide or particles wherein a portion or all of the surface of an oxide is coated with a conductive oxide, an electron emission source is provided that can emit electrons at low voltages, and that favorably maintains both conductivity of the electron emission source and strong adhesiveness between the carbon material for an electron emission source and a cathode electrode substrate.
