An electron-emitting device includes a substrate, first and second carbon films
disposed so as to have a first gap between the first and second carbon films on
a surface of the substrate, and first and second electrodes electrically connected
with the first and the second carbon films respectively, wherein the carbon film
has a region showing orientation, and a direction of the orientation is in an approximately
parallel direction along the substrate surface. Thereby, it is possible to improve
thermal and chemical stability of a carbon film and stabilize good electron emission
characteristics over a long period.
