Zusammenfassung:Disclosed an emission device includes a substrate; a cathode electrode formed on the substrate; a gate electrode crossing the cathode electrode and insulated from the cathode electrode; and an electron emission region electrically connected to the cathode electrode. The cathode electrode includes a main electrode with an inner opening portion, an isolate electrode placed in the opening portion and spaced apart from the main electrode by a distance, and a resistance layer disposed between the main electrode and the isolate electrode. The isolate electrode has a via hole. The electron emission region contacts the isolate electrode, and is placed in the via hole. The isolate electrode has a first height, and the electron emission region has a second height smaller than the first height.
