PURPOSE: To provide an electron beam generating device which can be driven at low voltage, and an image display and a recording device in which the beam generating device is used by improving the modulation efficiency of an electron beam.
CONSTITUTION: In an electron beam generating device having an electron emission element comprising element electrodes 3 provided thereon with an electron emitting portion 4 therebetween, and modulating electrodes 2 for modulating an electron beam emitted from the element, the electron emission element and the modulating electrodes are formed on the same substrate and are arranged so that the distance L by which each modulating electrode projects upward from an electron emitting face is equal to or greater than the distance S from the center of the electron emitting portion to each modulating electrode. The device can then be driven at low voltage and damage to the element is reduced and the convergence of the electron beam is enhanced, so the device can be suitably used in an image display and a recording device, etc.
