Abstract: The invention generally relates to the technical field of devices using the effect to emit electrons out of a solid into vacuum due to high electric field strength. Such devices are usually called field emission devices. The invention relates more specifically to the structure of a field emission device, to the method of fabricating a field emission device, and to the use of a multitude of field emission devices in the technical field of flat panel displays. The inventive structure of a field emission device (15) comprises an individual series resistor for each electron emitting tip (1), wherein the series resistor is formed by the tip (1) itself. The tip (1) comprises a body (9) of a first material with high resistivity and an at least partial coating (7) of a second material with low work function, wherein the body (9) of the first material forms the series resistor and the coating (7) of the second material provides for electron emission.
