Abstract: A field emission device having cold cathode devices including an emitter and a lead electrode, and the field emission device is provided with the plural kinds of cold cathode device groups classified based on the emission property of the cold cathode device. This field emission device has a member for allowing the cold cathode device group to perform emission by successively changing the cold cathode device group that mainly performs emission based on the difference in the emission property. Thus, it is possible to maintain the emission current at a predetermined necessary value or more and to realize the long lifetime of the field emission device.
