面の高品質化が進められている。Plasma display panels (FDP) are becoming widely used as a display device to replace CRT displays because they can provide a large display screen with a small depth. Therefore, as well as increasing the density of display dots and lowering prices, the quality of display screens is also increasing.

の上面の表示面に文字や図形が表示される。Figure 2 is a cross-sectional view of the main parts showing the structure of PDP II. The PDPII has a glass substrate 1 on the display side, a glass substrate 2 on the back side, and h-shaped tc ht. :-x electrode 3 and Y'F! 18ii4, x, y
It is composed of dielectric layers 5 and 6 covering the electrodes 3 and 4, protective layers 7 and 8 made of magnesium oxide (MgO), and a sealing glass 9 that seals the surroundings, and the internal discharge space 10 includes: For example, a mixed gas of neon and xenon is sealed. Light emission occurs due to discharge in the display cells defined at each intersection of the X electrode 3 and the Y electrode 4, and the combination of the display cells that emit light causes the glass substrate l

した光を外部へ漏洩させる必要がないので、製造コスト
面で有利な厚膜法により形成されることが多い。The X electrode 3 and the Y electrode 4 can be formed by a thin film method such as vapor deposition or sputtering, or a thick film method by printing and burning a conductive paste. Since there is no need for leakage, the thick film method is often used, which is advantageous in terms of manufacturing cost.

ラスなどの低融点ガラスからなる。The dielectric layers 5 and 6 are for sustaining a discharge that has occurred once by applying a discharge sustaining voltage, and are made of low melting point glass such as lead glass.

めに、黒色の塗装が施される。Usually, the bottom surface of the glass substrate 2 on the rear side is painted black in order to make the display clearer, that is, to increase the contrast of the display.

体Ｎ６を着色することにより、表示品質の向上が図られ
ている。By the way, as mentioned above, when forming the Y electrode 4 by the thick film method, a paste containing silver as a main ingredient is generally used. However, the surface of this silver paste becomes white due to oxidation during firing. The white Y electrode 4 stands out on the display surface, especially when the back surface is painted black, resulting in a reduction in display quality. For this reason, the display quality is improved by coloring the dielectric material N6 on the back side, as disclosed in, for example, Japanese Unexamined Patent Publication No. 61-74239.

いた。In addition, in the case of Y electrode 4 using a thin film method (for example, a three-layer electrode of chrome-copper-one-chromium), the Y electrode 4 itself does not deteriorate the display quality, but even in that case, the display quality may deteriorate due to peeling of the paint film. In order to prevent deterioration and reduce manufacturing man-hours by omitting the painting process, the dielectric layer 6 on the back side may be colored instead of painting the back side. Conventionally, such a colored dielectric layer 6 has been produced by applying a low melting point glass paste mixed with a coloring agent to the surface of the glass substrate 2 provided with the Y electrode 4 by screen printing, and then baking the glass paste layer. It was formed by admonishing.

表示品質が低下するという問題があった。However, as mentioned above, in the conventional plasma display panel manufacturing method in which the dielectric N6 is formed by burning a glass paste layer of IN mixed with a colorant, residual bubbles etc. may appear on the surface of the dielectric N6. Irregularities and protrusions are likely to occur. As a result, the dimensions of the discharge gap become non-uniform, causing variations in discharge characteristics between each display cell, and the light emitted by the discharge is diffusely reflected by the uneven portions of the surface of the dielectric layer 6, and the diffusely reflected light is Appears as a bright spot on the display screen,
There was a problem that display quality deteriorated.
本発明は、上述の問題に鑑み、誘電体層の表面の凹凸な

ている。SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to eliminate unevenness on the surface of a dielectric layer and to prevent deterioration in display quality.

が軟化する。In the invention of claim 2, as shown in FIG. 1, a glass paste containing a coloring agent is applied to the surface of the substrate 2 provided with the electrode 4 on the back side, and heat treatment is performed to form the first glass layer 6a. forming a glass paste containing no colorant on the first glass layer 6a to form a second glass layer 6b, and integrating the first glass layer 6a and the second glass layer 6b by heat treatment, Colored dielectric layer 6 covering electrode 4 on the back side
It is designed to take shape. [Function] The first glass layer 6a containing a colorant is covered with the second glass layer 6b not containing a colorant. By heat treatment in this state, the first glass layer 6a and the second glass layer [6b

２ガラスＪｉ６ｂの表面に凹凸が生じる。At this time, irregularities occur on the surface of the second glass Ji6b due to outward diffusion of bubbles (outgassing) and the like.

Next, a glass paste that does not contain a colorant, that is, a glass paste suitable for transparent glass that is obtained by removing the colorant from the glass paste of the first glass layer 6a, is applied over the first glass layer 6a. , is applied over the first glass layer 6a and dried to form a second glass layer 6b consisting of a paste layer [FIG. 1(d)].

ｅ）］。After sequentially laminating the first glass layer 6a and the second glass layer 6b in this way, the glass substrate 2 is heated at a temperature higher than the transition temperature of the low melting point glass (550 to 58
0°C), maintain that temperature for 60 to 90 minutes, and then cool naturally to room temperature. Through this heat treatment, the organic solvent etc. evaporate and the first glass layer 6a and the second glass layer 6b are vitrified and integrated, and a single layer of dielectric material N6 colored black is formed by the diffusion of the colorant.

６の表面の凹凸がなくなり、その表面が平坦となる。As described above, the glass paste was applied twice to form the first glass layer 6a containing a colorant and the second glass layer 6b not containing a colorant, and these two layers were integrated by heat treatment. In the dielectric layer 6, the viscosity of the second glass layer 6b is higher than the viscosity of the first glass N6a compared to a conventional one formed by applying heat treatment to an IN glass layer containing a colorant.
Since the viscosity of the dielectric layer 6 is smaller than that of the dielectric layer 6, the unevenness on the surface of the dielectric layer 6 is eliminated in a short heat treatment time, and the surface becomes flat.
