2. Description of the Related Art Generally, a PDP has a structure in which a pair of electrodes, which are regularly arranged, are provided on two opposing glass substrates, and a gas mainly containing Ne, Xe or the like is sealed between them. Then, a voltage is applied between these electrodes,
By generating an electric discharge in a minute cell around the electrode, each cell is caused to emit light to perform display. In order to display information, regularly arranged cells are selectively discharged and emitted. There are two types of PDP, a direct current type (DC type) in which electrodes are exposed in the discharge space and an alternating current type (AC type) in which an electrode is covered with an insulating layer. Both types are different in display function and driving method. Further, it is classified into a refresh driving method and a memory driving method.

FIG. 1 shows an example of the structure of an AC type PDP. This figure shows a state in which the front plate and the back plate are separated from each other. As shown in the figure, two glass substrates 1 and 2 are arranged in parallel and facing each other, and both of them serve as a back plate. The stripe-shaped ribs 3 provided in parallel with each other on the glass substrate 2 hold the glass substrate 2 at regular intervals. On the back side of the glass substrate 1 which is a front plate, a composite electrode composed of a transparent electrode 4 which is a sustain electrode and a metal electrode 5 which is a bus electrode is formed in parallel with each other, and a dielectric layer 6 is covered to cover the composite electrode.

This AC type PDP is a surface discharge type, and has a structure in which an AC voltage is applied between the composite electrodes on the front plate and the electric field leaks into the space to discharge. In this case, since the alternating current is applied, the direction of the electric field changes according to the frequency. Then, the phosphor layer 10 is caused to emit light by the ultraviolet rays generated by this discharge, and the observer visually recognizes the light transmitted through the front plate.

It is manufactured by providing the phosphor layer 10 on the. As a method of forming the address electrodes 8, a method of forming a film of an electrode material on the glass substrate 2 by a vacuum vapor deposition method, a sputtering method, a plating method, a thick film method or the like, and patterning the film by a photolithography method, , A method of patterning by a screen printing method using a thick film paste is known. The dielectric layer 9 is formed by screen printing or the like. Rib 3 is overprinted by screen printing,

The phosphor layer 10 includes red (R),
It is formed by selectively filling phosphor pastes for each color of green (G) and blue (B), and then drying and firing. Conventionally, it is necessary to fill the phosphor pastes. Screen printing is used. That is, the step of selectively filling the phosphor paste between the ribs by screen printing and drying is repeated three times, and then firing is performed.
However, as the PDP becomes finer and has a larger area, it is necessary to use a screen plate corresponding to it. However, such a screen plate is stretched or distorted.
Since it is difficult to align the back plate with the glass substrate, it becomes difficult to accurately fill the phosphor paste.

For this reason, recently, a phosphor paste is also efficiently applied between the ribs by a dispenser method. This dispenser method uses a coating head having a plurality of ejection holes in a direction perpendicular to the coating direction, and the phosphor paste is coated between the ribs while the coating head is moved relative to the substrate. According to this method, it is possible to simultaneously coat three colors of phosphor paste by using a coating apparatus incorporating a plurality of coating heads.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since the back plate for P has many components such as electrodes, dielectric layers, ribs, and phosphor layers, it is necessary to go through many complicated steps for one glass substrate when manufacturing it.
Therefore, in order to reduce the manufacturing cost, recently, the manufacture of substrates by multi-sided mounting has become the mainstream. As the multiple imposition, a pattern imposition as shown in FIGS. 2 to 4 is generally used, but in any case, it is divided into respective surfaces after the final step or at some point. Thus, the glass substrate 2 must be cut.

[0009] Usually, for this cutting for each surface, a cutting line α is made in the glass substrate 2 using a disk-shaped cutter C as shown in FIG. 5, and the cutting is performed at the cutting line α. Done in steps. However, the high strain point glass used for the glass substrate of the PDP has a crack called a cullet when a score line is formed to cause a small piece and the cut surface is not clean. Therefore, in order to prevent the occurrence of this cullet, oil such as kerosene is generally applied in advance to the portion to be cut.

However, when cutting the glass substrate constituting the back plate for PDP, if oil is applied to the portion to be cut, only the water can be washed in order to prevent the components from being affected, so the oil is completely removed. It is not possible to do so, and there is a concern that it may remain as a stain and that there will be problems in the heat treatment in the subsequent process.

BEST MODE FOR CARRYING OUT THE INVENTION The method for cutting a glass plate of the present invention is a method for cutting a glass plate made of high strain point glass, which comprises applying a water-soluble organic solvent to a site to be cut in advance on a cutter. A score line is made and a fold is made at the score line.

In the above glass plate cutting method, the organic solvent is required to have a boiling point of 100 ° C. or higher at atmospheric pressure. That is, the boiling point is 10
This is because if the temperature is lower than 0 ° C., it is volatilized between application and cutting and the effect of preventing cullet generation is lost. Among the organic solvents that satisfy this condition, it is preferable to use alcohol having a boiling point of 100 ° C. or higher at atmospheric pressure. Alcohol having a boiling point of 100 ° C. or higher at atmospheric pressure not only shows good results when used alone, but also causes cullet as a mixed solvent mixed with another alcohol having a boiling point of 100 ° C. or lower. Can be used for prevention.

Further, in the above glass cutting method, as for the blade edge angle of the cutter, if the blade edge angle of the cutter is small, the cutting line into the glass plate becomes deep and cullet is likely to occur. On the other hand, if the cutting edge angle is too large, it is difficult for the score line to be cut into the glass plate, and the folding may not be successful in many cases. Therefore, it is preferable to use the blade angle of the cutter in the range of 140 to 160 degrees.

As a preferred specific example to which such a glass plate cutting method is applied, there is a case where the back plate for PDP is manufactured by multi-sided mounting as described above. That is, it is necessary to cut the glass substrate so that the rear plate for PDP manufactured by multi-sided mounting is divided into the respective surfaces after the final step or at some point, and the above glass plate is used for cutting the glass substrate. The cutting method is applied.

PDP to which the above glass plate cutting method is applied
The first manufacturing method of the rear plate for use is as follows. That is, one glass substrate made of high strain point glass, electrodes,
After forming each component of the dielectric and rib with a pattern of two or more screens, apply a water-soluble organic solvent in advance to the site to be cut, then make a cutting line with a cutter and cut it. After the glass substrate is cut so as to be divided into the respective surfaces by performing folding at the score line, at least the vicinity of the cut portion of each glass substrate is washed with water, and then the phosphor layer is formed. . Also in this case, it is preferable to chamfer the cut end face and perform the corner cutting process after cutting the glass substrate.

Since the phosphor layer is porous and relatively soft, glass fragments may bite into it and may not be removed by washing with water. Therefore, as in the case of the first manufacturing method, by cutting the glass substrate and washing it with water before forming the phosphor layer, the glass fragments generated at the time of cutting cut into the phosphor layer and cannot be removed. It can be lost.
