ABSTRACT OF THE DISCLOSURE Display devices adapted to display one or more characters side-by-side in one or more rows and including an insulating member having a plurality of parallel grooves therein, or end supports, a plurality of elongated conductors each seated in one of the grooves or recesses and carrying along its length a cathode segment for each character position, and an anode associated with each group of the display segments. The cathode segments, together with an anode, can be selectively energized to display a character at any desired posi- tion. The devices also include a top insulating plate or sheet capable of transmitting light and providing a sealed flat panel containing an ionizable gas at a pressure capable of sustaining cathode glow dis- charge. A unitary shield which may be an insulating member or an electrode has portions shielding each group of cathode segments and its anode from the others.
