Abstract:
1. A field emission device comprising: an anode plate, an anode electrode and a phosphor layer are formed inside of the anode plate; a cathode plate, a plurality of electron emission sources for emitting electrons which correspond to the phosphor layer and a gate electrode having gate holes through which the electrons pass are formed inside of the cathode plate; a mesh grid which is provided between the cathode plate and the anode plate and in which a plurality of electron-controlling holes are formed in a region corresponding to the gate holes; a spacer which supports the mesh grid between the anode plate and the mesh grid; and insulating layers which are formed on both sides of the mesh grid and have windows through which the plurality of electron-controlling holes are exposed and which correspond to a region where the plurality of electron-controlling holes are formed.
