Abstract: PROBLEM TO BE SOLVED: To maintain optical clearness and transparency of at least two plates, for example, of glass forming the display by preventing a gas discharge groove of a light emitting gas discharge display from being heated or contaminated at the time of manufacture. SOLUTION: While the display is being manufactured, a by-pass tube (bridge tube) 36 is used for isolating a gas discharge groove 16 of a light emitting gas discharge display 10 from heat and contamination. The by-pass tube 36 is removed after that so that the light emitting discharge passage through the groove. In such a manner, a high quality and reliable lamplight or display for advertisement can be provided.
