The partition walls constituting the discharge display cell are required to have a high degree of shape accuracy.However, when the partition walls are formed by the above-described manufacturing methods, the printability is deteriorated due to wettability with the insulating substrate and the minuteness of the partition walls. Defects at the time of molding such as chipping, specifically, defects such as peeling of the partition walls from the insulating substrate in the manufacturing process, dimensional changes due to deformation of the partition walls, and cracks of the partition walls themselves may occur, particularly at the ends of the partition walls. There is a common problem that it is difficult to obtain flatness and uniformity of thickness, which not only reduces the production yield as it is, but also tends to reduce the dimensional accuracy of the discharge display cell, making it difficult to achieve high definition. The challenge It was.

う課題があった。In the case of forming a partition having a two-layer structure by the above-mentioned thick film printing method, a step of exchanging two kinds of pastes is required. It is easy to cause an increase in manufacturing cost and a decrease in production yield due to an increase in the number, and when a sandblasting method or a photolithography method is adopted, if the adhesion and drying conditions of the two layers are not optimized, the two layers are not used. , And the production of the display colors is extremely difficult. Therefore, in any of the methods, a large number of discharge display cells with high definition are provided.
There has been a problem that it is difficult to inexpensively manufacture a PDP used for a color display device for a large screen of up to 60 inches.

When the content of the composition for forming the partition walls or a part thereof is less than 15% by weight, the content is less than 15% by weight. The shape retention of the powder component such as glass, which is the main component of the composition, becomes insufficient, causing the partition wall molded article to sag and deform as described above.

る。On the other hand, if the content exceeds 50% by weight, carbon remains in the inside of the fired partition walls from the viewpoint of thermal decomposability, resulting in the generation of impurity gas and the like during emission of PDP, and a decrease in display luminance. This leads to a reduction in display quality such as a decrease in luminous efficiency and a reduction in the display life of the PDP.

くなる。When the content of the organic compound having an epoxy ring is less than 1% by weight, the composition for filling the defective portion of the partition wall cannot provide sufficient shape-retaining property, and the above-mentioned powder is removed when the binder is removed. The body component collapses, making it impossible to repair the partition walls. As a result, the plasma generated by the discharge leaks from the defective portion, and accurate display of the discharge display cell cannot be performed.
【００３４】一方、前記含有量が４０重量％を越える

When the content exceeds 45% by weight, on the other hand, if the content exceeds 45% by weight, the fluidity of the composition is so high that the composition drips from the partition end face to the partition side face after printing. As a result, as a result, the function of increasing the luminance of the white partition walls cannot be realized, and furthermore, color variation or the like due to a luminance change for each discharge display cell is caused.

れ、最終的に光漏れがあった。As a result, in Sample No. 1 in which the amount of the epoxy ring organic compound added was less than 1% by weight, the black layer collapsed from the end of the partition wall when the binder was removed, and in Sample No. 9 exceeding 45% by weight, The fluidity of the black paste increases, causing dripping from the edge of the partition wall at the time of application and falling on the white layer. In the sample No. 10 of the comparative example in which the epoxy ring organic compound is not used, defects such as collapse and dripping are found at the edge of the partition wall. All were recognized, and there was finally light leakage.

るＰＤＰ用隔壁が得られる。As described above, the composition for barrier ribs of PDP of the present invention and the method of manufacturing barrier ribs for PDP using the same comprise an organic additive containing an organic compound having a certain range of epoxy ring. A glass or ceramic powder, or a mixture of them and a coloring agent is used as a composition for partition walls, and the mixture is used to form the entire partition walls constituting the discharge display cell by various conventionally known molding methods, or After compensating for shape defects such as height insufficiency or cracks and deformation of the partition walls, the partition wall molded body or the filling portion is cured in the air,
Then, other than baking integrally with the insulating substrate, since a light-absorbing black colored layer cured in the air is applied to the end face of the partition on the display side, the wettability of the partition composition is improved. In addition, it is possible to increase the adhesion strength between the insulating substrate and the partition wall, and to prevent shape defects such as dropout or deformation of the partition wall, thereby improving the production yield and increasing the productivity, and further, increasing the precision dimension. In addition to obtaining shaped partition walls, it is extremely easy to repair the shape defects of the partition walls, and at the same time, it is possible to provide a black colored layer firmly adhered by a simple method, and to develop color with adjacent discharge display cells. It is possible to obtain a partition wall for a PDP that can clearly distinguish and enhance the contrast, easily improve the size of the screen, and achieve high definition with a greatly improved luminous efficiency.
