BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. The embodiment of the present invention is not limited to this.

(First Embodiment) FIG. 1 is a sectional perspective view showing a schematic structure of a plasma display panel according to a first embodiment of the present invention. The same parts as those in the structure of the general plasma display shown in FIG. 7 are designated by the same reference numerals.

The front plate 1 has a structure in which a plurality of display electrodes 5 covered with a dielectric layer 3 and a protective film 4 of a MgO vapor deposition film are provided on a transparent and insulating substrate 2 such as glass. ing. The display electrode 5 is a pair of a scan electrode 6 and a sustain electrode 7, the scan electrode 6 is composed of a transparent electrode 6a and a bus electrode 6b formed thereon, and the sustain electrode 7 is a transparent electrode 7a. And a bus electrode 7b formed thereon.

The back plate 8 is provided with a plurality of data electrodes 11 covered with an insulating layer 10 on an insulating substrate 9 such as glass, and the data electrodes 1 on the insulating layer 10 are attached.
A stripe-shaped partition wall 12 is provided between the first and second electrodes in parallel with the data electrode 11.
The structure is such that the phosphor layer 13 is provided over the side surface of the.

The front plate 1 and the rear plate 8 are arranged so as to face each other across the discharge space 14 so that the scan electrodes 6 and the sustain electrodes 7 and the data electrodes 11 are orthogonal to each other. The discharge space 14 is filled with at least one rare gas selected from helium, neon, argon, and xenon as a discharge gas, and is partitioned by the partition 12 to form the data electrode 11, the scan electrode 6, and the sustain electrode 7. The discharge space 14 at the intersection of the positions operates as a discharge cell 15.

Now, the bus electrode 6b of the scan electrode 6, the bus electrode 7b of the sustain electrode 7, and the data electrode 11 will be described in more detail. FIG. 2 shows the bus electrodes 6b of the scan electrodes 6.
And the bus electrode 7b of the sustain electrode 7 are shown as an example. The data electrode 11 also has the same structure as the bus electrodes 6b and 7b, and therefore the description thereof will be omitted below. FIG. 2 shows the scan electrodes 6 and the sustain electrodes 7 in a cross section perpendicular to the substrate 2. The scan electrode 6 is composed of a transparent electrode 6a and a bus electrode 6b formed thereon, and the sustain electrode 7 is a transparent electrode 7
The bus electrode 6b and the bus electrode 7b (hereinafter simply referred to as bus electrodes 6b and 7b) have a two-layer structure, for example.

When forming the bus electrodes 6b and 7b having the two-layer structure, an inorganic solid substance and an organic compound are provided on the transparent electrode 6a and the transparent electrode 7a on the substrate 2 (hereinafter simply referred to as the substrate 2). The electrode material is formed by stacking two layers of the electrode material and then firing, and the content ratio of the inorganic solids of the electrode material for forming the first layers 16a and 17a is set to the second layer 16b and The feature is that the content of the inorganic solid is larger than that of the electrode material for forming 17b. The effect of this is as follows. Usually, when a mixture of an inorganic solid and an organic compound is fired, the organic compound burns and disappears due to firing, so that volume shrinkage occurs after firing with respect to the applied state before firing, and the volume shrinkage is This causes the electrodes 6a and 7a to be separated from the substrate 2. However, in the present embodiment, the content of the inorganic solids in the electrode material of the first layers 16a and 17a is high, and therefore, the amount of the inorganic solids at the time of firing is small. Since the volume shrinkage is small, peeling from the substrate 2 is unlikely to occur, and the second layers 16b and 17b are formed by coating on the first layers 16a and 17a.
Even a and 7a as a whole are not separated from the substrate 2.

As a specific example, the electrodes 6b and 7b are made of a mixture of Ag and glass powder as an inorganic solid material and an acrylic resin as an organic compound, and the weight of the inorganic solid material and the organic compound is used. The ratio of the first layer 16a
And the electrode material for forming 17a were 60% by weight: 40% by weight, and the electrode material for forming the second layers 16b and 17b were 50% by weight: 50% by weight. The film thickness at the time of coating was 4 μm, and the total film thickness of both was 8 μm. When firing is performed after such a stacked state, the electrodes 6b and 7b can be formed in a good state without peeling from the substrate 2 or warping of the ends, and finally, The scan electrodes 6 and the sustain electrodes 7 could be formed without any problem.

Further, in order for the bus electrodes 6b and 7b to function well as electrodes, it is required that the electric resistance be low, and for that purpose, a certain thickness is required. However, only the electrode material containing a high proportion of inorganic solids
When the bus electrodes 6b and 7b having such a layered structure are to be formed, since the electrode material contains a large amount of inorganic solids, the proportion of the organic compound is low, and such an electrode material is used as a screen. If a thick film is formed on the substrate 2 by a printing method or the like, printing problems such as poor separation from the screen plate will occur. However, in the present embodiment, an electrode is formed using an electrode material having a large content ratio of the inorganic solids only in the region where the volume shrinkage with respect to the substrate 2 at the time of firing is a problem, and the second layer is formed thereon. 16
Since b and 17b have a laminated structure using an electrode material having a normal inorganic solid content, the above-mentioned problems do not occur when the electrode material is applied.

FIG. 3 shows a case where the electrodes 6a and 7a have a three-layer structure. Also in this case, as in the description with reference to FIG. 2, the content ratio of the inorganic solids in the electrode material for forming the first layers 16a and 17a is changed to that of the electrode material for forming the second layers 16b and 17b. By making it larger than the content ratio of the inorganic solid matter, it is possible to prevent the electrodes 6a and 7a from peeling off from the substrate 2 and curling back.

As described above, according to the plasma display of the present embodiment, problems such as peeling and warpage of the electrodes occur during firing when forming electrodes having a relatively thick film such as bus electrodes and data electrodes. It is possible to realize a plasma display panel with less energy consumption.

explain. Since many parts of the present embodiment are the same as those of the first embodiment shown in FIG. 1, the same parts are designated by the same reference numerals in the following description, which is characteristic of the present embodiment. Only the part will be described.

FIG. 4 shows the bus electrodes 6b of the scan electrodes 6 and the bus electrodes 7b of the sustain electrodes 7 in a cross section perpendicular to the substrate 2 in the plasma display panel according to the present embodiment.

The scanning electrode 6 is composed of a transparent electrode 6a and a bus electrode 6b formed thereon, and the sustain electrode 7 is composed of a transparent electrode 7a and a bus electrode 7b formed thereon, and the electrode 6b. And 7b have, for example, a two-layer structure. When forming the electrodes 6b and 7b having the two-layer structure, for example, an electrode material containing an inorganic solid substance and an organic compound on the transparent electrode 6a and the transparent electrode 7a (hereinafter simply referred to as the substrate 2) on the substrate 2 The first layer is formed by applying two layers of
The feature is that the coating thickness of 6a and 17a is made thinner than the coating thickness of the second layers 16b and 17b.

The effect of this is as follows. Usually, when a mixture of an inorganic solid and an organic compound is fired, the organic compound burns and disappears due to firing, so that volume shrinkage occurs after firing with respect to the applied state before firing, and the volume shrinkage is Although the electrodes 6a and 7a become a cause of peeling from the substrate 2, in the present embodiment, the coating thickness of the electrode material of the first layers 16a and 17a is made thin, so that the volume contraction during firing is suppressed. The absolute value becomes smaller. As a result, peeling from the substrate 2 is less likely to occur. The second layers 16b and 17b are the first layer 1
Since it is formed by coating on 6a and 17a, the electrode 6a
And 7a as a whole will not be separated from the substrate 2.

As a specific example, the electrodes 6b and 7b are prepared by using a mixture of Ag and glass powder as an inorganic solid material and an acrylic resin as an organic compound as an electrode material. The weight ratio of the first layer 16a
And 17a and the second layers 16b and 17b were the same, and were 50% by weight: 50% by weight. Then, the film thickness at the time of coating is set to 2 μm for the first layers 16a and 17a.
m, the thickness of the second layers 16b and 17b is 4 μm,
The total film thickness of both is 6 μm. After firing in such a laminated state, the electrodes 6b and 7 were baked.
b can be formed in a good state without peeling from the substrate 2 or warping of the end portion, and finally,
The scan electrodes 6 and the sustain electrodes 7 could be formed without any problem.

As described above, according to the plasma display of the present embodiment, problems such as peeling and warping of the electrodes occur during firing when forming electrodes having a relatively thick film such as bus electrodes and data electrodes. It is possible to realize a plasma display panel with less energy consumption.

FIG. 5 is a diagram illustrating the method of manufacturing the plasma display panel according to the present embodiment. Here, the structure of the plasma display panel manufactured by the method of manufacturing a plasma display panel according to the present embodiment is substantially the same as that shown in FIG. 1, and the same parts are denoted by the same numbers for the sake of explanation. In addition, in the present embodiment, the electrode 6b

Are patterned. Specifically, the transparent electrodes 6a and 7a can be made of ITO or tin oxide added with antimony, and the thickness thereof is, for example, about 10
It is about 00Å.

Next, as shown in FIG. 5B, an electrode material is applied on the transparent electrodes 6a and 7a to form first layers 16a and 17a. Here, the electrode material includes, for example, an inorganic solid substance of Ag and glass powder and an organic compound having an acrylic resin as a main component, and the mixing ratio of the inorganic solid substance and the organic compound is 60% by weight: 40% by weight.

When firing the electrode material of the first layer 16a and 17a and the electrode material of the second layer 16b and 17b, each electrode material is a mixture of an inorganic solid substance and an organic compound.

However, in the method for manufacturing the plasma display panel according to the present embodiment, when the first layers 16a and 17a are formed, since the electrode material having a large inorganic solid content is applied, The volume shrinkage at that time becomes small, and peeling from the substrate 2 becomes difficult to occur. Since the second layers 16b and 17b are formed by coating on the first layers 16a and 17a, the electrodes 6a and 7a as a whole are not separated from the substrate 2.
