Abstract:
PROBLEM TO BE SOLVED: To provide an electron emitting element capable of continuously operating for a long time.SOLUTION: The electron emitting element is provided with a first electrode, an insulator layer that is formed on the first electrode and has an opening, a second electrode that is formed on the insulator layer, arranged in opposite to the first electrode across the opening and overlapped by the insulator layer, and a fine particle layer that lies between the first and second electrodes and the insulator layer and is composed of insulating fine particles and conductive fine particles. By applying voltage between the first electrode and the second electrode, an electron emitted by the first electrode is accelerated in the fine particle layer and is configured to pass through the second electrode.
