Method of production of electron source substrate provided with electron emitting elements and method of production of image forming apparatus using the substrate

摘要

A novel process for producing an electron source substrate is disclosed for formation of electron-emitting element at high efficiency with less shape irregularity. In the process, the region for electroconductive film formation is divided into plural subregions on which an electroconductive film is formed respectively. In forming the electroconductive film by application of plural liquids, the time interval between the application of the two drops is controlled to be larger than the time length necessary for suppressing the spreading of the succeedingly applied liquid within an allowable limit. <IMAGE> <IMAGE>
