Abstract:
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 Al2O3, TiO2, and SiO2. 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.
