2. Description of the Related Art A plasma display panel (hereinafter simply referred to as a PDP) is a monochromatic surface discharge display device using a neon gas discharge, and has been used as a display of a notebook personal computer or an information display device in a car.
Since the PDP does not require very fine processing such as a cell gap in a liquid crystal display, the PDP is being developed as a display of 40 inches or more for a large TV screen.

[0003] However, in the case of a color display, three times as compared with a single color.
Since twice the number of cells is required, a pixel having a smaller pixel size than a conventional PDP has been required. Furthermore, in the case of a high-definition wall-mounted TV, it is necessary to form high-definition pixels over a wider screen.

A PDP has a DC type and an A type depending on a driving method.
There are two types of the C type, and the DC type is originally superior in terms of the richness of gradation expression as a TV, but has a problem that the life of the electrode is short, the structure is complicated, and the production is difficult. On the other hand, the AC type has a stripe-shaped partition wall, has a relatively simple structure, and is easy to manufacture. Therefore, recently, only the AC type has been developed.

As a method for forming the partition, there are a printing method, a sand blast method, an embedding method and the like. The sand blast method is a method in which a partition member is applied uniformly on the entire surface of a substrate, and after drying, a resist mask for sand blast is formed on the surface by a photolithographic method or the like, and is considered to be the most stable at present. However, there are some problems as described below.

<Amount of Resin in Partition Member> A certain amount of resin is required to maintain the strength of the partition during processing and to reduce the amount of side etching when cutting the partition, but the amount of resin is large. When this happens, the machinability deteriorates and the throughput decreases.

<Mask Strength> The mask must have the strength to withstand the impact of sand used in sand blasting (hereinafter simply referred to as sand). In practice, the mask material is made of a flexible resin to maintain cushioning properties. Is used and requires some thickness. At present, those having a size of about 30 to 50 μm are used. Since the mask is thick, the resolution is 30 μm.
The pattern is up to about m.

Hard and fine sand is required, but if it is too fine, the time required for cutting becomes very long. Therefore, it is necessary to set an appropriate particle size according to the size of the pattern. Sand with high hardness may cut the substrate and electrodes, so calcium carbonate, glass beads, Si

Conventionally, the partition wall width is as wide as 60 to 80 μm, so that the contact area of the mask is large and the adhesion force is high. And the space (cut part) is as wide as 120-140 μm,
Since the flow of sand was slow, side etching was difficult to proceed. However, as the densification progresses, the width of the partition walls becomes narrower and the space becomes narrower, so that the side etching easily proceeds, and the sand acts to turn over the back surface of the mask, so that the mask is easily peeled. The striped partition wall is cut from both left and right sides of the partition wall to form a wall (portion of FIG. 2 (A)), but the tip portion is also cut from the left and right as well as from the front (portion of FIG. 2 (B)). Cutting very fast.

As a countermeasure against this, it is conceivable to increase the amount of resin in the upper layer of the partition member to increase the adhesion to the mask. However, in the case where the partition wall width is 30 to 50 μm, even in this case, there is a problem that the mask at the partition wall tip portion is peeled off during processing and the length of the partition wall tip portion is not uniform. For this reason, there has been an attempt to prevent separation by increasing the area of close contact of the mask by making the vicinity of the end longer than the effective surface, making the shape of the mask at the tip of the partition wall thicker or rounding, or the like. However, basically, since the forefront portion is shaved from three sides, it is still easy to be turned up, and it cannot be said that the state is sufficiently stable. In some cases, the curling may even spread from the edge toward the middle, and it is easy to make defective products.

Embodiments of the present invention will be described below. FIG. 1 shows an example of a cross-sectional structure of an end of a partition wall of a plasma display panel according to the present invention before sandblasting. By coating the upper layer partition member (3) on the substrate (1) to the outside of the lower layer partition member (2), the step is moderated so that the dry film (4) can be securely bonded at the step. Further, by increasing the amount of resin of the upper partition member, the step portion on the side surface of the end portion of the lower partition member is covered with the upper partition member having a large amount of resin, and the partition pattern mask of the dry film does not end on the lower partition forming layer. By extending and covering the portion to the glass substrate, cutting of the side surface of the partition wall tip portion is reduced and the adhesion of the dry film is increased. As a result, the adhesion of the mask is improved at the tips of the stripe-shaped partition walls during sandblasting, and the partition walls can be formed stably.

A low-melting glass or the like can be used as the partition member in the present invention. Ethylcellulose is used as the resin component in the upper partition member more than the lower partition member, and about 0.8 to 2.0% by weight is preferable for the lower partition member and about 2.0 to 3.5% by weight for the upper partition member. Range. The resin amount of the lower partition wall member varies depending on the width of the partition wall and the width of the space, and is minimized in order to increase the cutting speed of sandblasting. In the upper layer, the finer the narrower the width of the partition wall, the lower the adhesion of the dry film mask, so that the upper layer is made larger. By increasing the resin content of the upper partition member, the adhesion of the mask is improved, and the partition can be formed stably.

In the present invention, the thickness of the upper partition member is preferably 10 to 20% of the thickness of the lower partition member.
If the thickness is less than 10%, it is difficult to obtain a smooth surface, and a black paste may be used to improve contrast.
At that time, a sufficient concentration cannot be obtained. In addition, since the paste is difficult to level and bubbles remain, it is not preferable. When the thickness is more than 20%, the cross section of the partition wall is doubled, and the neck portion of the partition wall becomes constricted. Not preferred.

As described above, according to the present invention, when a stripe-shaped partition wall is formed by a sandblast method,
The partition is formed of two layers, a lower layer and an upper layer, and the step of the lower layer, which is the end of the partition, is made gentle by coating the upper layer, so that the dry film mask can be formed so as to cover the side of the end of the partition to form a dry film mask. Mask peeling can be prevented. Furthermore, by forming the upper partition wall forming layer as a partition wall member having a large amount of resin, the adhesion of the dry film mask is improved even when a narrow partition wall is formed, and it becomes possible to eliminate defects due to mask peeling and stably cut. Was. In addition, since the amount of resin in the lower partition wall forming layer can be suppressed, processing can be performed without lengthening the sandblasting time.
