Therefore, a plurality of display colors can be realized on the surface of the front substrate 14 by selectively executing the voltage application via a control / drive circuit (not shown). For example, if only the discharge cells 36 belonging to the first discharge region 22 are turned on, red light is emitted, and if only the discharge cells 36 belonging to the second discharge region 24 are turned on, green light is emitted to both discharge regions. If the corresponding discharge cells 36 are simultaneously turned on, yellow light which is a mixed color of red and green is obtained. In addition, when the width of the comb-shaped discharge portions 22a and 24a in each discharge region and the thickness of the partition member 20 are made as small as possible, when only one discharge region is turned on, display unevenness is eliminated. The display colors can be realized evenly over the entire display surface, and when both discharge regions are simultaneously turned on, the degree of color mixing can be improved. Incidentally, in this embodiment, the width of each comb-shaped discharge portion 22a, 24a is set to 2 mm, and the thickness of the partition member 20 is set to 1 mm.

However, after the vacuum evacuation / gas filling device connected to the main pipe 46 is operated to perform vacuum evacuation in each discharge region at the same time, Ne is introduced into both discharge regions through the main pipe 46. Fill with a mixed gas of He. Then, the lower end of the branch pipe 48a connected to the first discharge region 22 is heated and melted by a gas burner to hermetically seal it. Next, after the Ne and He gas in the second discharge region 24 is exhausted through the main tube 46, He and X are introduced into the second discharge region 24 through the main tube 46.
The mixed gas of e is filled. Then, the second discharge region 24
The lower end of the branch pipe 48b connected to is heated and melted by a gas burner and hermetically sealed. Finally, as shown in FIG. 5, the boundary between the main pipe 46 and the connecting pipe 50b is heated and melted by a gas burner and sealed off, and then the sealed portion of each branch pipe 48 is cut to cut off each discharge region. The filling of the discharge gas is completed.
As described above, a thick portion is provided near the lower end of the inner surface of each branch pipe 48.
Since 54 is formed, the above airtight sealing can be performed very easily by heating the portion with a gas burner.

According to the filling method described above, the vacuum exhaust and gas filling of each discharge area can be realized by one vacuum exhaust / gas filling apparatus, so that the manufacturing equipment and the process can be simplified. Of course, it is needless to say that an independent evacuation / gas filling device may be connected to each discharge region, and evacuation and filling of the discharge gas may be performed individually.

In the multi-color light emitting type gas discharge display panel according to the present invention, the inside of one envelope formed by a pair of front and rear substrates is provided with two discharge regions via a partition member. Airtightly divided, because each discharge region is filled with a discharge gas forming a different emission color, by selectively generating discharge emission in the discharge cells belonging to one of the discharge regions, Although it is a single gas discharge display panel, different display colors can be realized for each discharge region. In addition, since the comb-teeth-shaped discharge parts of the first discharge area and the comb-teeth-shaped discharge parts of the second discharge area are arranged alternately, when discharge light emission is simultaneously generated in both discharge areas. It is possible to realize a third display color that is a mixed color of both.
