ABSTRACT OF THE DISCLOSURE An improved display device of the Type using self-sustained discharge as a source of electrons for cathodoluminescence is operable at relatively greater pressures so as to lower the necessary striking potential to the Paschen minimum and includes an improved grid structure for selectively controlling the transport of electrons from the sustained discharge to a high voltage screen, and constructed so as to limit positive ion space charge formation therebetween.
