DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel used for a flat panel television or an information display, and more particularly, to a plasma display in which an exhaust groove for exhaust is provided in a partition located at a non-discharge gap portion. Panel and its manufacturing method.

[0002]

2. Description of the Related Art In the structure of a conventional plasma display panel (hereinafter referred to as PDP), a partition 40 and a glaze layer 6 are formed.
0, the exhaust groove is not formed in the glass substrate 50 and the like, and the manufacturing method is mainly such that the partition wall 40 is formed by embedding a partition wall material (paste) in a dry film resist (hereinafter referred to as DFR) having a pattern cut. There are a sand blast method and a cutting method of cutting the partition wall 40 with a mold. These methods are currently used for manufacturing the stripe-shaped partition wall 40, but are not enough to form an exhaust groove. Therefore, the partition 40, the glaze layer 6
0. As a technique of forming an exhaust groove in the glass substrate 50, a method of laminating a plurality of DFRs having different sandblast resistance and sandblasting to form an exhaust groove to increase a panel exhaust conductance is performed.

FIGS. 7 and 8 show a plan view and a sectional view of a conventional structure. The exhaust path is configured so that it is only in a parallel direction along the partition wall 40.

Further, in connection with the prior art, (1) a configuration in which a plurality of exhaust grooves are formed in front / rear substrates of a flat type display and communicated with each other in the periphery thereof to increase the exhaust conductance (particularly, Kaihei 08-031346),
(2) As a configuration in which a partial side cross section of the partition wall 40 of the PDP is narrowed, an exhaust space is provided between the back plate and the partition plate to reduce exhaust resistance (Japanese Patent Laid-Open No. 06-26742).
8), (3) the plurality of island-shaped third dielectrics formed except for the discharge display portion on the second substrate of the PDP correspond to the island-shaped first and second cell members formed on the first substrate. There is a configuration in which the exhaust space is reduced by opposing the cell space so as not to make the cell space closed (Japanese Utility Model Application Laid-Open No. 56-079964). The technique of increasing the exhaust conductance is easily achieved by making exhaust grooves and cutouts. Reference (1) has nothing to do with PDP, but exhaust conductance (exhaust resistance) is reduced by employing exhaust grooves and notches in all three examples.

[0005]

However, in the conventional method, if an exhaust groove is formed not in the non-discharge gap portion but in the discharge gap, electrons leak to adjacent cells through the exhaust groove. Will emit light,
There was a problem that the lighting was wrong.

The present invention has been made in view of such a problem, and an object thereof is to provide an exhaust groove at a position corresponding to a non-discharge gap to prevent light emission to an adjacent cell. Another object of the present invention is to provide a plasma display panel having a high yield and a high reliability, and a method of manufacturing the plasma display panel.

Embodiments of the present invention will be described below in detail with reference to the drawings. The schematic structure of the plasma display panel according to the present embodiment includes an exhaust groove 30 provided in a partition 40 on the data side 200, a scan electrode 10 and a non-discharge gap 20, as shown in the plan view of FIG. FIG. 2 is a cross-sectional view taken along the line AA ′, and a glass substrate 50,
The glaze layer 60, the partition wall 40, the glaze layer 60 as a material for the scan side, and the glass substrate 50 are roughly configured in this order, and the scan electrodes are formed on the scan-side glaze layer 60,
It is arranged in a direction crossing the partition wall 40.

The partition wall 4 adjacent to the non-discharge gap 20
An exhaust groove 30 is formed at 0. In this configuration, the exhaust groove 30 is formed in the non-discharge gap 20 portion.
Therefore, the effect that the exhaust conductance increases regardless of the light emitting unit is provided. The existence of the exhaust groove 30 in the non-discharge gap 20 according to the present invention allows the conventional partition wall 4
The degree of freedom of the exhaust, which was only in the direction parallel to 0, is changed to the exhaust groove 30.
It can be seen that the exhaust conductance is remarkably improved from the direction.

The non-discharge gap 20 according to the present embodiment is
The exhaust groove 30 of the section is manufactured by the method shown in FIG.

The method according to the present embodiment employs a step called a sand blast method. A plurality of DFRs having different sandblast resistances are attached and patterned, and then the partition walls 40 and the exhaust grooves 30 are formed by sandblasting.

First, (a) a partition paste is applied on a substrate in a solid state, (b) a first DFR is applied, and (c) exposure is performed so as to form a partition pattern. After that, (d) a second DFR is attached, and (e) exposure is performed so as to form an exhaust pattern. (F) This is developed, (g) sand blasting is performed, and (h) the exhaust groove 30 is formed and quieted.

Since the first and second DFRs have different sandblast resistance, the depth of the exhaust groove 30 can be controlled by the blast rate of the sandblast and the blast resistance of the DFR. Instead of two DFRs, a plurality of DFRs may be attached. However, the exhaust groove 30 made in the present invention
In the case of the phosphor, there is a possibility that the phosphor may protrude into the surrounding cells via the exhaust groove 30 at the time of applying the phosphor, but this can be solved by controlling the depth of the exhaust groove 30.

As shown in FIG. 5, by providing the exhaust groove 30 also in the glaze layer 60 on the data side 200, the partition wall 40,
The exhaust groove 30 can be controlled in two stages of the glaze layer 60. Further, the exhaust groove 30 can also be provided in the glaze layer 60 on the scan side 100. As a method of providing a step in the glaze layer 60 of the non-discharge gap 20 part, a method of forming a step by sandblasting after the formation of the glaze layer, for example, when forming four layers when forming the glaze layer 60, one or two layers are printed in a solid pattern. The third and fourth layers are printed with a screen having a pattern such that the non-discharge gap 20 is not printed in the 20th portion to form a step.

As a method of forming the exhaust groove 30 in the partition wall 40, sand blast is applied to the formation method, but it is also possible to apply formation by a mold.

As another embodiment of the structure, the exhaust groove 3
The shape of 0 is not limited to a square. For example, there are shapes as shown in FIGS. This is also to prevent the phosphor from protruding into other cells when printing the phosphor.

As shown in FIG. 6, an exhaust groove 30 is formed only on the scanning side 100 as an example of a measure against the protrusion of the phosphor into another cell. The advantage of this method is data side 2
In the case of 00, if the exhaust groove 30 is formed and the conventional method is used, the protrusion of the phosphor into the cell can be completely prevented. Therefore, when looking only at the data side 200, only in the partition direction, the exhaust path is widened by the exhaust groove 30 formed on the scan side 100, and as a result, the exhaust conductance is increased.

It is to be noted that a mold method can be employed for the partition 40 in addition to the sand blast method. DFR in the sandblast method
The shape of the partition walls can be easily controlled by devising the paste or the paste. In the die method, the partition walls 40 having various shapes can be formed by using different molds.

The scanning side 100 and the data side 200
A method of excavating with a sand blast, water pressure, laser, or the like, or a method of shaving with a grinder can be adopted for the glass substrate 50, and the excavating depth can be adjusted by adjusting the sand blast pressure, water pressure, and laser intensity. In addition, the method of digging with water pressure has the merit that washing can be performed simultaneously with digging.

For the glaze layer 60 on the scan side 100 and the data side 200, a method of forming a step by sandblasting after printing the glaze layer 60 and a method of forming a step by changing a screen plate for each layer when printing the glaze layer 60 are adopted. did. In the sand blast method, the step can be adjusted by the sand blast pressure. In the method of adjusting the step by the screen, the step can be formed only by changing the screen plate without changing the number of times of printing at the time of printing.
Further, the step can be adjusted by the number of times of printing on each screen.

A partition 40 having an exhaust groove 30 is formed by forming a mold on a substrate on which a partition material is printed solid. Since the partition walls 40 formed by this method are formed by press-molding with a metal mold from above the solid printed partition material, the time required for reducing the number of steps can be reduced.

The plasma display panel and the method of manufacturing the same according to the embodiment have the following effects because they are configured as described above.

An exhaust groove 30 for improving the exhaust conductance is formed in the non-discharge gap 20 in view of the structural relationship of the PDP. The increase in the exhaust conductance increases the ability to remove impurity gas in the panel, and the exhaust Baking time can be reduced. Therefore, the yield and the reliability can be improved.

Since the non-discharge gap does not discharge,
By forming the exhaust groove here, electrons do not leak through this exhaust groove, preventing erroneous lighting and affecting adjacent cells.

As an example of each of the manufacturing methods, as a method of forming the exhaust groove 30 in the glass substrate 50, there are a method of digging with water pressure or laser, and a method of grinding with a grinder, in addition to sandblasting.

The number, position, shape, and the like of the above-mentioned constituent members are not limited to the above-described embodiments, but may be set to a number, position, and shape suitable for carrying out the present invention.

[0027]

Since the present invention is configured as described above, the following effects can be obtained. The effect of increasing the exhaust conductance is provided. That is, the exhaust groove 30 secures an exhaust path, thereby improving the exhaust conductance of the panel. As a result, (a) the ability to remove impurity gas in the panel is increased.
(B) The exhaust baking time can be reduced. Thereby, the yield and reliability of the product can be improved.

Further, by forming the exhaust groove 30 in the non-discharge gap, electrons do not leak to the adjacent cell through the exhaust groove 30, so that light emission of the adjacent cell can be prevented.
