Abstract
A field emission cathode capable of permitting a display to be carried out at increased density and a circuit incorporated therein together with an FEC to exhibit satisfactory characteristics and being driven according to a static drive system. A plurality of control lines and data wires are arranged in a matrix-like manner on a monocrystalline Si substrate, to thereby form element regions on the substrate. The element regions each are formed therein with a circuit element, on which a field emission section is laminated. The circuit elements each include a first transistor connected to both data wire and control wire and functioning as a switching element, a capacitor serving as a circuit for storing therein a signal input thereto, and a second transistor for amplifying a signal input thereto and feeding it to the field emission section.
