There is provided an electron emitting device including a substrate, a pair
of electrodes formed on the substrate and being apart from each other, a
pair of electrically conductive films formed on the electrodes,
respectively, and being apart from each other, a distance between the
electrically conductive films being shorter than a distance between the
electrodes, and an electron emitting film formed between the electrically
conductive films, the electron emitting film containing boron and at least
one of carbon and nitrogen.
