Abstract:
1. An electron-emitting device comprising: (A) first and second electrodes disposed on an electrically-insulating substrate, wherein a gap is formed between said first and second electrodes; (B) a first layer formed on said first electrode and having an oxide of Ti, an oxide of Zr, or an oxide of Nb on a surface thereof; and (C) a fibrous carbon grown through a catalyst particle disposed on a sidewall surface of said first layer facing a side of said second electrode, so that said fibrous carbon does not connect said first electrode to said second electrode, wherein only the sidewall surface of said first layer facing the side of said second electrode is exposed and other surfaces of said first layer are covered with a material on which a fibrous carbon does not grow as compared with said first layer, and wherein said material on which a fibrous carbon does not grow as compared with said first layer, is at least one of Ta, Cr, Au, Ag, Pt, and materials of a same kind as a material making said catalyst particle.
