Abstract:
A method for producing an electron source substrate comprising a plurality of first wires, a plurality of second wires electrically insulated through insulating layers from said first wires, and a plurality of electron-emitting devices connected to said first wires and to said second wires, on a substrate, said method comprising the following steps:(A) a step of forming the first wires; (B) a step of forming the insulating layers each as a stack of M layers by repeatedly carrying out steps of laying and baking an insulating material on said first wires M times, M being an integer satisfying M&gE;3; and (C) a step of forming the second wires on said insulating layers, wherein an N-th insulating material used in formation of an N-th insulating layer, N being an integer satisfying 2&lE;N&lE;Mâˆ’1, is baked at a temperature lower than a softening point of said N-th insulating material, and wherein baking temperatures in formation of an (N+1)th to said M-th insulating layers are not more than the baking temperature in formation of said N-th insulating layer.
