Abstract
The wirings on an electron source substrate are formed to intersect with each other in a matrix so as to address the electron emission devices on the substrate. First and second wirings intersect with each other on a crossing point. As such a crossing point, an insulating layer is placed between the first and second wirings. To ensure insulation, a plurality of insulating layers are laminated. According to the present invention, a wiring pattern is provided on the substrate with a conductive paste and baking the wiring pattern of the conductive paste to form the first wiring. Subsequently part of the first wiring is coated at the crossing point with an insulating paste and baking the insulating paste to form a first insulating layer. The coating thickness of the insulating layer formed adjacent to sidewalls of the crossing point is substanially equal to the height of the first wiring.
