A display device employing a planar array of elements disposed on a dielectric substrate. The dielectric substrate is affixed to a metallic plate which functions as an anode element in an electrical discharge while a perimetrical metallic strip serves as a cathode element. These components are disposed between two non-conductive plates in which a partial vacuum is created and backfilled with an inert gas. The non-conductive plate proximate the display surface of the array of elements is transparent enabling an undistorted view of the segments. A relatively large potential applied between the anode and the cathode elements sustains the electrical discharge thereby providing a source of free electrons in the area between the elements and the transparent plate. The application of a small bias voltage between selected segments of the array of elements and the anode element produces a thin luminous sheath over the energized segments which provides a sharply defined display.
