Abstract: Provided are a field emission device and a field emission display device using the same. The field emission device includes a cathode portion having a substrate, a cathode electrode formed on the substrate, and a field emitter connected to the cathode electrode; a field emission-suppressing gate portion formed on the cathode portion around the field emitter and surrounding the field emitter; and a field emission-inducing gate portion having a metal mesh with at least one penetrating hole, and a dielectric layer formed on at least a part of the metal mesh, wherein the field emission-suppressing gate portion suppresses electrons from being emitted from the field emitter, and the field emission-inducing gate portion induces electrons to be emitted from the field emitter. According to this configuration, the conventional problems of the field emission device including a gate leakage current, electron emission caused by an anode voltage, electron beam divergence can be significantly improved.

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.
