<p>PROBLEM TO BE SOLVED: To provide an electron-source substrate in which a positioning margin for the process of forming an interlayer insulating layer is large enough to reduce the time for the process. SOLUTION: In a matrix wiring board on the surface of which first wiring 2 and second wiring 4 that cross almost at right angles via an interlayer insulating layer 3 are formed, a pair of roughly trapezoidal element electrodes 1, 1 connected to the first 2 and second 4 wiring are formed in the regions of the matrix wiring board which are surrounded by the first 2 and second 4 wiring. An electron emitting part is formed in the microclearance 5 between the pair of element electrodes 1, 1.</p> |
