An electron-emitting device manufacturing method comprising a gas removal step
of removing a gas dissolved in a liquid containing a formation material of an electroconductive
film in which an electron emitting area is to be formed, a temperature adjusting
step of adjusting a temperature of the liquid from which the gas is removed, and
a droplet discharge step of discharging droplets of which the temperature is adjusted
by droplet discharge means in an ink jet manner, while controlling relative positions
of the droplet discharge means and a substrate on which the electroconductive film
in which the electron-emitting area is to be formed is formed. The droplets are
thereby applied to a predetermined position on the substrate.
