Abstract
To provide a method for manufacturing an electron source having electron-emitting devices with excellent electron-emitting property arranged on a substrate and enabling an image-forming apparatus capable of displaying an image with high brightness and uniformity to be enhanced in terms of screen size and production scale. The method for manufacturing the electron source includes a step of disposing a plurality of units and a plurality of wirings connected to the plurality of units on a substrate, each unit including a polymer film and a pair of electrodes with the polymer film interposed therebetween, and a step of forming electron-emitting devices from the plurality of units by repeatedly performing a process including a selecting substep of selecting a desired number of units from the plurality of units, a resistance-reducing substep of reducing resistance of the polymer films of the selected units and a gap-forming substep of forming a gap in each of the films formed by the resistance-reducing substep.
