Abstract
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.
