<p>PROBLEM TO BE SOLVED: To manufacture many electron emitting elements at low cost on a board by dropping solution containing metallic element to form a conductive film, between a pair of or a plurality of electrodes provided on the substrate, and providing the film with an electron emitter. SOLUTION: Element electrodes 2 and 3 are made a distance L1 (2μm) apart on a substrate 1. Next, a conductive film 4 is made to contact with the element electrodes 2 and 3 by discharging the liquid drop 24 consisting of solution containing metallic element from a liquid drop giving device (ink jet ejector) 7. Next, by foaming processing, cracks are brought into existence in the conductive film, and an electron emitter 5 is made. By such constitution, the conductive film is arranged equally in accurate position, and electron emitting property becomes stable. And, this is used for an electron source board, a display panel, an image forming device, etc., excellent in performance.</p> |
