Patent ID: 6986692

Claim:
A method of producing an image-forming apparatus wherein a face plate having phosphors of the three primary colors is opposed to a rear plate comprising a plurality of electron-emitting devices, each having a first electrode and a second electrode, and a plurality of column-directional wirings and row-directional wirings are connected to the plurality of electron-emitting devices, and the phosphors of the three primary colors are disposed in the same order repeatedly along the row direction, said method comprising: (a) a step of arranging a plurality of first electrodes and second electrodes on the rear plate such that first and second electrodes of each of the electron-emitting devices are opposed to each other in the row direction; (b) a step of forming the plurality of column-directional wirings, wherein each of the column-directional wirings connects commonly a plurality of the first electrodes; (c) a step of forming the plurality of row-directional wirings, wherein each of the row-directional wirings connects commonly a plurality of the second electrodes, intervals of the row-directional wirings are larger than those of the column-directional wirings, each of the row-directional wirings cross some of the column-directional wirings; and the row-directional wirings are formed so as to be insulated from the column-directional wirings; and (d) a step of applying a liquid containing at least a metal or a semiconductor so as to connect the first and second electrodes to each other according to an ink jet method, and wherein said step of forming the column-directional wirings comprises: a step of forming a film comprising a photosensitive material and an electroconductive material on the rear plate; a step of irradiating desired areas of the film with light; a step of patterning the film; and a step of baking the patterned film.
