Abstract
A substrateis provided with conductive cathode tracks and a field electron emission material on the tracks. Septaand pillarsare provided as raised elements over the emission material. An electrically insulating layer is formed over the emission material and raised elements, such that boundary walls are formed in the insulating layer where it contacts the raised elements. The raised elementsare then removed, to leave emitter cells and voids for other components, defined by the boundary walls with the insulating layer. A gate electrode is provided over the insulating layer.
