This discharge display panel comprises a front glass substrate (1), a rear glass substrate (2) and an XY matrix-shaped anode (3) sandwiched between them.
It consists of a cathode (4), each anode (3) being separated by an insulating barrier (5). Back glass substrate (2)

れトリガー電圧の経時的増大も顕著であった。This discharge display panel uses a pilot fire called a trigger discharge in order to improve the discharge characteristics of the main discharge between the anode (3) and the cathode (4). This is caused by the voltage applied between the trigger electrode (7) and the cathode (4), but the actual discharge due to the presence of the dielectric layer (6) between the trigger electrode (7) and the cathode (4). Occurs between the wall of the dielectric layer where the wall voltage (8) is induced and the cathode (4). In order to raise the wall voltage, it is better to increase the dielectric constant of the dielectric layer (6), but if it is too large, the lines of electric force are concentrated on the bottom surface of the cathode and the wall voltage does not rise effectively. Therefore, at present, glass having a dielectric constant ε of about 6 to 10 is used. However, the trigger voltage becomes 300 V or more, and sometimes causes dielectric breakdown of the dielectric layer (6). This also leads to poor manufacturing yield. On the other hand, the surface of the dielectric layer (6) was contaminated by cathode sputtering, and the increase of the trigger voltage with time was remarkable.

0) is composed of a front glass substrate (1), a rear glass substrate (2) and an XY matrix-shaped anode (3) and cathode (4) which are sandwiched between them and face each other across a discharge space. , Each anode (3) is separated by an insulating barrier (5). In the rear glass substrate (2), the trigger electrode (7) is connected to the cathode (4) below the cathode (4) through the first insulating layer having a uniform thickness, that is, the dielectric layer (6). It is provided in parallel. Thus, in the present invention,
In particular, between the cathodes (4) and the first dielectric layer (6) thereunder, a plurality of stripe-shaped second second layers arranged parallel to each other on the first dielectric layer (6). An insulating layer, that is, a dielectric layer (11) is provided.

る。Further, a trigger electrode (7) is formed on the upper surface of the rear glass substrate (2), and a first dielectric layer (6) having a uniform thickness is formed on the entire surface by a thick film printing method. A striped second dielectric layer (11) is formed on the dielectric layer (6) at predetermined intervals, and a cathode (4) is formed thereon by a thick film printing method. In this case, the width of the stripe-shaped dielectric layer (11) can be made wider than that of the cathode (4). Each of these components is baked after screen printing.
Next, the two glass substrates (1) and (2) are arranged so as to face each other so that the anode (3) and the cathode (4) are orthogonal to each other,
Frit seal. After that, heating and exhausting, gas filling (for example, Ne-Ar gas), final sealing, and other steps are performed to complete the process.

なり、その分トリガー電圧の低減が図られる。According to this structure, each cathode (4) is formed on the first dielectric layer (6) via the plurality of stripe-shaped second dielectric layers (11) arranged in parallel with each other. So
The wall voltage induced on the first dielectric layer (6) and the surface becomes high, and the trigger voltage can be reduced accordingly.

方が壁電圧VWが高くなる。That is, the present invention is compared with the conventional example with reference to FIGS. 5 and 6 showing the equipotential surface. V T = 24 on the trigger electrode (7)
This is the case where 0V, 80V is applied to one cathode (4), and 0V is applied to the other cathode (4). In the present invention shown in FIG. 5, since there is a second dielectric layer (11) formed in a stripe shape on the first dielectric layer (6), induction is caused between the wall of the dielectric layer and the cathode. The wall voltage V W generated becomes higher than that in the conventional example of FIG. 6 by the amount of the equipotential surface that cuts into the second dielectric layer (11). Moreover, even if we consider an equivalent circuit, (Where V T is the voltage to be applied to the trigger electrode,
Cg is the capacitance between the cathode and the surface of the first dielectric layer, and Cd is the capacitance between the trigger electrode and the surface of the first dielectric layer. The wall voltage V W is higher in the present invention.

命化を図ることができる。Further, by providing the stripe-shaped second dielectric layer (11), the creepage distance between the surface of the cathode (4) and the surface of the first dielectric layer (6) becomes longer than that of the conventional type. Therefore, even if the cathode material is attached to the surface of the first dielectric layer (6) between the adjacent cathodes (4) by the cathode sputtering, the insulation deterioration between the cathodes (4) hardly occurs. Therefore, the life of the discharge display panel can be extended.

きる。On the other hand, in the configuration of FIG. 3, the first dielectric layer (6)
Can be made of a material having a high dielectric constant ε, and the striped second dielectric layer (11) can be made of a material having a low dielectric constant ε. With this configuration, electric field concentration on the bottom surface of the cathode is eliminated,
Furthermore, the wall voltage can be effectively induced. That is, the first
By increasing the dielectric constant of the dielectric layer (6), the wall voltage can be increased. In addition, since the high dielectric constant material can reduce the voltage drop in that layer, the layer thickness of the first dielectric layer (6) can be thinned to the extent that dielectric breakdown does not occur, and the trigger voltage, that is, the trigger electrode. It is possible to reduce the voltage to be applied to. In this case, the stripe-shaped second dielectric layer (11) has a low dielectric constant of Zn-based glass, Al 2 O 3
TiO 2 (titania), barium titanate, lead titanate, strontium titanate, etc. can be used for the first dielectric layer (6) requiring high dielectric constant of several 10%. Mixed glass can be used. With this configuration, the trigger voltage can be reduced to 200 to 250V.
