Abstract
This invention discloses an electron source manufacturing method including the step of applying a voltage to a plurality of conductive members by applying a potential to first portions of the plurality of conductive members serving as at least part of electron-emitting devices via a wiring commonly connected to the plurality of conductive members, and applying a potential to second portions of the plurality of conductive members, wherein the potential applied to the second portions of the plurality of conductive members is set to relax the difference in voltage applied to the plurality of conductive members owing to the difference between potentials at portions respectively connected to the first portions of the plurality of conductive members in the wiring commonly connected to the plurality of conductive members.
