A luminous display device is disclosed as including a transparent or translucent top body part having a rear surface; a bottom body part having a front side, a rear side, and a trough extending along at least part of the front side of the bottom body part to form a pre-defined pattern; in which the rear surface of the upper body part is in fused sealing relationship with the front side of the bottom body part to form a sealed discharge chamber between the trough and the upper body part; an ionizable gas filling the chamber; and two openings in the bottom body part each having a first end communicating with the chamber and a second end communicating with an electrode, the electrodes being energizable to ionize the gas in the chamber to produce light discharge of the pre-defined pattern.
