Patent ID: 6991949

Claim:
A manufacturing method of an electron emitting apparatus comprising the steps of; (A) forming a carbon-group-material layer on an electrically conductive layer, and (B) forming a fluoride-carbide-containing thin film on the surface of the carbon-group-material layer from a fluorine-containing hydrocarbon gas, thereby to obtain an electron emitting portion comprising the carbon-group-material layer and the fluoride-carbide-containing thin film formed on the surface of the carbon-group-material layer, in which a dispersion of carbon-nano-tube structures in a binder material is applied onto the electrically conductive layer and then the binder material is fired or cured to form the carbon-group-material layer in the step (A), and in which a metal compound solution in which carbon-nano-tube structures are dispersed is applied onto the electrically conductive layer, and then the metal compound is fired, to form the carbon-group-material layer in the step (A).
