Abstract:
There are provided a stable electron-emitting device with less fluctuation in electron-emitting properties and a method of fabricating the electron-emitting device. The electron-emitting device has a substrate; a plurality of columnar first regions respectively orientated substantially perpendicular to the surface of the substrate; a second region provided between the respective first regions higher than the first regions in resistance; and an electron emission layer covering the columnar first regions and the second region.
