シールすることにより作製する。 The gas discharge display panel according to the present invention includes an insulating substrate 1,
Electrodes 3 and 4 are formed on each of the electrodes 2 using a thin aluminum film or a thick silver film using thick film printing technology. Subsequently, the electrodes 3 and 4 are covered with a low melting point lead glass film 5,
Cover with step 6. Furthermore, an insulating layer 7 for preventing discharge is formed on the portion of the substrate 2 where the opposing electrodes overlap in the vertical direction.
It is formed by patterning it by silk screen printing and firing it in an air atmosphere. The material used is a mixture of low melting point lead glass with a softening temperature of 400 to 500 DEG C. and aluminum oxide in a weight ratio of 3:7 to 7:3. The formed film thickness is 30 to 50 μm,
When the substrates 1 and 2 are opposed to each other, the electrodes 3 and 4 have the function of preventing discharge at the intersection (shown in FIG. 1B). Next, both substrates 1 and 2 are made of aluminum oxide.
The partition walls 8, 9 having a film thickness of 80 to 100 μm are formed by printing and firing a paste containing magnesium oxide as a main component and low melting point lead glass as a binder. The insulating substrates 1 and 2 formed as described above are made to face each other with the electrodes 3 and 4 facing each other in a positional relationship as shown in the schematic diagram of FIG. 1, and neon gas is injected to airtightly seal the surroundings. .

である。(5) Description of Effects The gas discharge display board according to the present embodiment described above exhibits discharge characteristics as shown in FIG. 3. The discharge area that becomes the display pixel is the part shown in FIG. 1A. The applied voltage V IN is a rectangular wave voltage with a duty of 50%. As the applied voltage V IN is increased, discharge suddenly starts at a voltage of V W , and thereafter, as the applied voltage increases, the discharge area expands, and the discharge current also increases accordingly. On the other hand, once the gas discharge display board is in a discharge state, it is possible to maintain the discharge state until the voltage VE is lower than V W by decreasing the applied voltage V IN .
従つて、本実施例のガス放電表示板は、第４図

を維持電圧VSに保ち適当に印加電圧をVE，VWと
すれば任意の位置での放電の維持が可能である。 Therefore, as shown in FIG. 4, the gas discharge display board of this embodiment starts discharging when the applied voltage V IN is set to V IN > V W , and maintains the discharge at V E < V IN < V W (at this time). (The voltage at which the voltage is maintained is the sustaining voltage VS. ), and the discharge can be stopped when V IN < VE . In other words, the applied voltage V IN
It is possible to maintain discharge at any position by keeping V S at the sustaining voltage and setting the applied voltages V E and V W appropriately.

飛躍的に高められた。 The gas discharge display board of this embodiment is different from conventional gas discharge display boards in that the pair of electrodes do not cross each other and face each other, but are arranged in parallel with a gap between them. Because of this feature, the memory function (corresponding to V W - V E in Figure 3) of gas discharge display boards has been dramatically improved.

とが可能である。 In addition, conventional memory-type gas discharge display boards used glass rods, etc. placed around the outer periphery of the display area to obtain a discharge gap, so in order to realize a large-area display board, a thick glass substrate was used. It was necessary to prevent the substrate from deforming due to atmospheric pressure. For this reason, there was a drawback that the weight of the gas discharge display board increased. However, in the case of this embodiment, since the partition walls are formed within the display area to determine the discharge gap, it is possible to realize a large-area display panel using a thin glass substrate.
