Electron-emissive drive units of electron-emissive elements capable of being arranged with a smaller pitch. FET and emitter array units exist in matrix element areas partitioned by a control wiring and data wiring. An exemplary unit is composed of four emitter arrays. The control wiring and data wiring are driven by first and second drive circuits, respectively. Corresponding arrays between units are connected by selection wiring and driven by a third drive circuit. The third drive circuit drives each unit of data wiring every time the drive circuit sequentially drives the four units of control wiring, and the emitter array drive circuit drives each emitter array selection wiring every time the drive circuit sequentially drives the three units of data wiring. Electrons can be emitted in units of arrays smaller than the unit.

A dispersion of carbon nanoparticles is prepared by monodispersing carbon nanoparticles in water droplets of a reverse micelle solution in which the water droplets are coated with amphiphilic molecules and dispersed in an organic solvent. In a method of preparing the dispersion of carbon nanoparticles, carbon nanoparticles and a monodispersion function material, e.g., ammonia, for imparting a polarity to surfaces of the carbon nanoparticles are added to the reverse micelle solution. The solution is then stirred, so that the carbon nanoparticles whose surfaces have the polarity are monodispersed in the water droplets of the reverse micelle solution. Further, a metal alkoxide is added to the solution and then stirring them, so that the surfaces of the carbon nanoparticles are coated with oxide of the metal.

The present invention provides carbon nanotubes perpendicularly and densely deposited over a wide area of a substrate. The carbon nanotubes are manufactured by supplying alternating-current power at a specific frequency between an anode and a cathode disposed in a reactor, and causing plasma to be generated between the anode and the cathode by introducing mixed gas containing an aliphatic hydrocarbon having 1-5 carbon atoms and hydrogen or mixed gas containing an aromatic hydrocarbon and hydrogen. The substrate is disposed between the anode and the cathode and held at a distance two times or less of the mean free path of a hydrocarbon cation from the anode.
