Abstract
A field emission element that can prevent one cathode electrode line from being completely disabled due to a short circuit between an emitter electrode and a gate electrode. One cathode electrode line consists of a stripe cathode conductor and plural island electrodes arranged on the one side of the cathode conductor. The gate electrode is disposed on the insulating layer overlaying the upper surface of each island electrode. The first resistance layer and the second resistance layer each having a different resistance value are laminated in a current control resistance layer. When excessive current flows through the emitter cone, the laminated thick-film portion is destroyed so that only the island electrode connected to the emitter cone is electrically separated off from the cathode conductor. One second resistance layer is locally laminated on the first resistance layer and for each of plural island electrodes.
