An electron emission source-forming composition includes a carbon-based material; a vehicle composed of a resin component and a solvent component; and at least one metal oxide with an average particle diameter in a range of 100 to 1,000 nm selected from AlO, TiO, and SiO. The electron emission source-forming composition is sintered under an air atmosphere during electron emission source formation. Therefore, carbon deposits after sintering and degradation of Carbon Nano-Tubes (CNTs) upon sintering can be remarkably reduced. As a result, the electron emission source formed using the composition has a high current density and the electron emission device using the electron emission source exhibits enhanced reliability.

Electron emission source, its method of fabrication, and an electron emission device using the electron emission source

The present invention relates to a composition for formatting an electron emission source of an electron emission device, and an electron emission source comprising the same. The composition comprises a paste comprising multi-walled carbon nanotubes exhibiting an RBM (Radial Breathing Mode) peak. The paste further comprises an inorganic powder, a binder resin, and an organic solvent. The electron emission source made from the composition of the present invention improves the lifetime and electron emission characteristics of the electron emission device by using multi-walled carbon nanotubes having excellent lifetime and electron emission characteristics.
