Abstract:
An electron-emitting device according to this invention has a cathode electrode, a first electrode, a second electrode, an insulating layer, a gate electrode, and an electron-emitting member. The gate electrode, the insulating layer, and the first electrode respectively have an opening communicating with each other. The electron-emitting member is provided on the cathode electrode, and at least a portion of the electron-emitting member is exposed in the opening. The second electrode is provided in the opening of the first electrode and electrically connected to the cathode electrode.
