Abstract
A field emission device includes a cathode, an anode, an emitter, a first adjusting electrode, and a second adjusting electrode. The emitter electrically connects to the cathode. The cathode, the first adjusting electrode, and the second adjusting electrode electrically connect to an electrode down-lead. The anode electrically connects another electrode down-lead. The cathode is disposed between the first adjusting electrode and the second adjusting electrode.
