An object of the present invention is to provide a field emission device capable of preventing occurrence of arc discharge due to application of high voltage. A first substrate, an electron emitter composed of a cathode, an emitter, and a gate formed on the first substrate are disposed at a predetermined distance from the first substrate. A second substrate 41 forming a vacuum space together with the substrate, a phosphor 54 formed on the second substrate 41 and emitting light by electrons emitted from the electron emitter, and a mesh grid 50 arranged on the electron emitter And a field emission device comprising: [Selection diagram] FIG. |
