摘要：
An electron-emitting device comprising a substrate, first and second carbon films disposed on the substrate, and first and second electrodes electrically connected to the first and second carbon films, respectively. The first and second carbon films are opposed to each other with a first gap interposed therebetween, and a portion of the substrate located between the electrodes comprises at least Si, O and N.
