Abstract:
A manufacturing method for manufacturing an electron source comprising a plurality of electron emitters comprising steps of:(a) preparing a substrate;(b) forming on a substrate plural pairs of electrodes, each pair comprising first and second electrodes, wherein said first and second electrodes are spaced by a gap and arranged in opposition to each other;(c) forming on said substrate plural first wirings according to a printing method so that said first wirings are arranged substantially in parallel, wherein at least one said first wiring is formed to overlap with a part of at least one said first electrode each of said first wirings comprises some of said first electrodes connected commonly;(d) forming plural insulating layers on said first wirings according to the printing method;(e) forming plural second wirings so that said second wirings are substantially normal to said first wirings and are electrically insulated from said first wirings, wherein said second wirings are formed substantially in parallel to a direction along which said first and second electrodes are opposed, and each of said second wirings are formed to connect commonly some of said second electrodes;(f) forming plural electrically conductive films on said substrate on which said first and second wirings are formed, wherein each of said electrically conductive film is formed to connect said first and second electrodes; and(g) forming an electron emission portion at each of said plural electrically conductive film, by applying a voltage to each of said pair of electrodes.
