Abstract: Provided are methods of manufacturing carbon nanotube (CNT) paste, to which a nano-sized particle is added, and a CNT emitter with high reliability for a field emission display (FED). The method includes the steps of: (i) dispersing CNT powder in a solvent; (ii) adding an organic binder to the solution in which the CNT powder is dispersed; and (iii) performing a milling process to adjust viscosity of the dispersion solution to which the organic binder is added, wherein a nano-sized metal particle is added in step (i) or (iii). Accordingly, the nano-sized metal particle is added as a metal filler of the CNT paste, and thus a metal may be melted at a low temperature at which CNTs do not deteriorate. Thus, adhesion between the CNT paste and a cathode may be improved, and resistance between the cathode and the CNT or between CNTs may be reduced. Further, the CNT paste manufactured by the above method is employed in manufacturing the CNT emitter to thereby obtain uniform emission of electrons from the CNT emitter and increase electron emission sites, and thus the reliability of the CNT emitter may be further improved.

Abstract: [Object] In an emitter of field-emission electron that includes a carbon film structure, a localized electric-field concentration is suppressed and an electric-current degradation or an electric-discharge phenomenon due to thermal deterioration is prevented from occurring. Moreover, a dispersion of electron emission is suppressed. Furthermore, in a field emission device to which the emitter has been applied, a desired function is achieved so that a more practical product is provided.
[Solution] An electron emitter includes a guard electrode 13 on the outer circumferential side of a carbon film structure 10 which is formed on a substrate 7 by plasma CVD method. This guard electrode 13 includes a curved surface portion (a curved surface portion that curves from top toward a side opposite to the film-forming direction) 13a convex in a film-forming direction of the carbon film structure 10. A curvature radius R1 of an outer-circumferential-side portion of the curved surface portion 13a is larger than or equal to a curvature radius R2 of a carbon-film-structure-side portion of the curved surface portion 13a.
