Display units and their fabrication methods

摘要

There are realized display units which can increase the emitting point density of nanotube electron emitters as electron emitters and have a good image quality and their fabrication methods. In nanotube electron emitters forming electron emitters 403, nanotubes 102 and granular support media 103 composed of an electric conductor are mixed with each other, at least one end of the nanotubes 102 and the support media 103 are adhered onto a substrate by melted metal adhesives 104, and the other end of the nanotubes 102 is oriented as a free end in the vertical direction to the substrate by the support action of the support media 103. This can increase the emitting point density of the electron emitters from below 1000 points/cm<2 >in a prior art to above 100000 points/cm<2>. An in-plane uniform emitting pattern enough to make practical use of emissive type flat-panel display units can be realized.
