Abstract
The rear substrate of an FED comprises data electrodes formed on a surface of the substrate, an insulating layer over the substrate covering the data electrodes, scan and common electrodes laterally disposed on the insulating layer such that they are parallel with each other and electron emitting elements, which emit electrons when they subject to electric field, connected between a scan electrode and a common electrode. The electron emitting elements have a middle portion narrower than end portions so that electron emitting surface area is located at a same location from emitter to emitter.
