2. Description of the Related Art FIG. 4 is an exploded perspective view showing the structure of one pixel of a conventional plasma display panel. In FIG. 4, FP is a front substrate, and BP is a rear substrate. The X and Y electrodes formed on the rear surface of the front substrate FP opposite to the display surface of the substrate body 10 are sustain electrodes, and are usually made of a transparent conductive material such as ITO or NESA. Reference numerals 11 and 12 denote bus electrodes, which serve to supply power to the sustain electrodes X and Y. Reference numeral 15 denotes a dielectric layer, and reference numeral 16 denotes a protective film made of an MgO film. On the other hand, 31 formed on the surface of the substrate body 20 of the back substrate BP is a stripe-shaped partition wall,
R, G, and B are excited by vacuum ultraviolet light,
This is a phosphor layer that emits blue light, and is applied on the surface of the substrate body 20 between the adjacent partitions 31 and on the side walls of the partitions 31. Also, 21, the rear substrate substrate body 20 has
Reference numerals 22 and 23 denote address electrodes for electrically writing light emitting and non-light emitting information therein. Two panels composed of a front substrate FP and a rear substrate BP shown in FIG. 4 are tightly sealed together so that a discharge space is formed therebetween, and a discharge gas is sealed in the discharge space. .

As shown in FIG. 5, in the first prior art, the sustain electrodes for adjacent cells C1 and C2 are X1, Y
1, X2, and Y2 are alternately arranged, and the gas discharge for display (sustain) is performed by a combination of the sustain electrode X1 and the sustain electrode Y1 and the sustain electrode X2 and the sustain electrode Y2. Discharge). In the figure, 1
Reference numerals 3 and 14 denote bus electrodes, and 31, 32, 33 and 34 denote partition walls. At this time, if a sustain discharge is generated between sustain electrode Y1 and sustain electrode X2, it is an erroneous discharge, which hinders accurate image expression. In order to prevent this, in the first prior art, it is usual to set an unpaired electrode interval between the sustain electrode Y1 and the sustain electrode X2 to a sufficient distance.

In the second prior art shown in FIG. 6, sustain electrodes Y1 and Y2 having the same potential, such as X1, Y1, Y2 and X2, are arranged next to each other to take measures against erroneous discharge. ing.

[0005]

Due to such a structure, in the conventional plasma display panel, there is a region where light is not emitted, such as between the sustain electrode Y1 and the sustain electrode X2 shown in FIG. It was a big hindrance.

As shown in FIG. 6, when the arrangement of the sustain electrodes is set to X1, Y1, Y2, X2, since both the sustain electrodes Y1, Y2 have the same potential, both the sustain electrodes Y1, Y2
Although no erroneous discharge is caused between the sustain electrodes X1 and Y1, the erroneous discharge between the sustain electrode X1 and the sustain electrode Y2 simultaneously occurs with the sustain discharge between the sustain electrode X1 and the sustain electrode Y1 as the interval is reduced to increase the effective light emitting area. It is easy to occur, and there are limits to the method.

Further, in the conventional plasma display panel, the light emitting performance of the phosphor layer differs for each of RGB. In general, since the emission intensity of blue (B) is weaker than the other two colors, only a white display at a low color temperature can be performed, and a conventional PDP is used.
Was not good at vivid-looking expressions.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has been made in order to increase the effective light emitting area of a cell and to make the cell brighter and to reproduce a vivid image at a high color temperature. And a substrate structure therefor.

Among the plurality of sustain electrodes, three successive sustain electrodes are defined as a first sustain electrode X1, a second sustain electrode Y12, and a third sustain electrode X2, respectively, as shown in FIGS. Sometimes, the first sustain electrode X1 and the second sustain electrode Y12
And a set of the third sustaining electrodes X2,
They are repeatedly arranged along the direction D2. That is, the second sustain electrode Y12 is disposed in the center of the pixel, and each of the upper and lower portions is parallel to the second sustain electrode Y12 with a predetermined discharge gap from the second sustain electrode Y12.
A first sustain electrode X1 and a third sustain electrode X2 are arranged. A bus electrode (second bus electrode) 1 for supplying power to the second sustain electrode Y12 is provided at the center of the second sustain electrode Y12.

Here, it should be noted that the arrangement relationship between the front substrate and the rear substrate in the present embodiment is that the first sustain electrode X1 and the second sustain electrode Y1 are arranged from the display surface side of the front substrate.
When the second and third storage electrodes X2 are viewed, the central portions of the second storage electrode Y12 and the bus electrode 13 are in the second horizontal partition wall 3 position.
6 and the first sustaining electrode X1
Is arranged between the top of the first horizontal partition 35 and the top of the second horizontal partition 36, and the third storage electrode X2 is connected to the top of the second horizontal partition 36 and the top of the third horizontal partition 37. It is to be arranged between the parts. In other words, the front substrate and the rear substrate are adhered to each other and the two substrates are sealed so that the bus electrode 13 is located above the top of the second horizontal partition 36. As a result, the second cell portion C2 and the third cell portion C3 in FIG. 2 are partitioned by the second horizontal partition 36, and the discharge regions of the two cell portions C2 and C3 do not overlap. C3 can be driven separately, and the second storage electrode Y12 and the bus electrode 13 are shared by the second cell portion C2 and the third cell portion C3. Similarly, the first horizontal partition wall 35 is
The two discharge regions of the cell portion C2 and the third cell portion C3 thereon are prevented from overlapping, and the third horizontal partition 37 is formed between the third cell portion C3 and the second cell portion C2 thereunder. The two discharge regions are prevented from overlapping. Moreover, each horizontal partition 3
Since both ends E1, E2 of 5, 36, 37 are connected to the side walls of the second and third partition walls 32, 33, the second phosphor layer of the second emission color and the second phosphor layer of the third emission color are used.

In order to distribute four cells forming one pixel to three colors, as shown in FIG. 2, the first color is a first cell part C composed of two vertical cells.
1 and the remaining two colors are assigned to the second cell portion C2 and the third cell portion, respectively.
It is distributed to each cell of the cell section C3. As a result, in the first cell section C1, between the first sustain electrode X1 and the second sustain electrode Y12 and between the third sustain electrode X2 and the second sustain electrode Y12.
The discharge area overlaps with the gap. On the other hand, since the second and third cell portions C2 and C3 are separately driven, the first to third lateral partition walls 35, 36 and 37 are provided at positions separating the discharge regions so that the discharge regions do not overlap. ing.

In the case of the first and second prior arts described above, in the portion where the second horizontal partition wall 36 of FIG. 1 is formed, the arrangement of electrodes spaced sufficiently apart to prevent erroneous discharge is required. Therefore, the portion was a non-light emitting region, which hindered the increase in brightness of the plasma display panel. On the other hand, in the present PDP, as described above, the second sustain electrode Y12 is shared by the upper and lower two cells among the four cells forming one pixel, and the second and third cell portions C2, With respect to C3, the overlapping discharge portion is completely partitioned by the horizontal partition walls 35, 36, and 37. On the contrary, in the first cell portion C1 which does not need to be partitioned, the large discharge space (the two upper and lower discharge regions in the related art) is positively provided. And a non-discharge area between them) is used as a discharge area. With this feature, it is possible to obtain a sufficiently wide effective light emitting area, and it is possible to realize an improvement in luminance.

Also, in this PDP, three pixels are required for four cells of one pixel.
The colors (R, G, B) must be assigned. Generally, two cells are assigned to blue cells having the weakest emission luminance, that is, the first color is set to blue (B), and the second color and the second color are set. By setting each of the third colors to either one of red (R) and green (G), a natural image having a high color temperature can be reproduced by maintaining RGB balance in white display.

Next, a method of manufacturing an AC surface discharge type plasma display panel having the cell structure shown in FIGS. 1 and 2 will be described. First, the procedure for producing the rear substrate will be described. That is, a back glass substrate (not shown) is prepared, and the patterns of the address electrodes 21 and 22 are formed by using silver as a main component.
It is formed on the surface of the rear glass substrate by a printing method or a photo process. Next, a white dielectric (not shown) having a function of reflecting phosphor emission is formed on the surface of the rear glass substrate by a printing method or the like so as to cover the address electrodes 21 and 22. Furthermore, on the surface of the white dielectric, a partition wall 31 having a predetermined height is formed by sandblasting or printing.
32, 33 and the horizontal partition walls 35, 36, 37 are formed in a shape as shown in FIG. Thereafter, the spaces formed by the partitions 31, 32, 33 and the horizontal partitions 35, 36, 37 are filled with the phosphor layers of the corresponding colors by a printing method. At this time, more preferably, a blue phosphor layer is applied and formed in a stripe shape on the upper portion of the address electrode 21, and the red and green phosphor layers are applied on the upper portion of the address electrode 22 so as to be alternately arranged. ·Form.

On the other hand, as for the front substrate, first, a front glass substrate (not shown) is prepared, and a transparent conductive film of NESA or ITO is formed on the front substrate by thermal CVD, sputtering or the like. The pattern shape is (X1, Y12, X
2), the second direction D2 of the second sustain electrode Y12
In the second direction D2 of the first and third sustain electrodes X1 and X2.
Is formed about twice as wide as the width, and the pattern of the sustain electrodes (X1, Y12, X2) is formed as one unit, and this repetitive pattern is formed. Next, the bus electrodes 14, 1
1 are arranged on the upper end of the corresponding first sustaining electrode X1 or on the lower end of the third sustaining electrode X2, and the bus electrode 13 is arranged on the central part of the second sustaining electrode Y12. Bus electrodes 14, 13, 1 by a printing method or the like.
Form one. Then, those parts X1, 14, Y1
2,13, X2,11, a transparent dielectric (not shown) is formed to a predetermined thickness over the entire surface so as to cover MgO.
By depositing a film (not shown) on the entire surface as a protective film,
The front substrate is completed.

Next, the completed front substrate and the rear substrate are frit-sealed. At this time, the bus electrodes 13 on the second sustain electrodes Y12 of the front substrate are connected to the red and green electrodes on the rear substrate. Both substrates or both panels are aligned so as to be located above the second horizontal partition 36 which is a partition of the phosphor layer (to overlap the partition 36 when viewed from the front side).

The PDP manufactured by the above method is then subjected to exhaust, gas filling, and aging steps.
Be completed.

Since the present PDP has the configuration as described above, the present embodiment has the following effects. That is, it is possible to increase the brightness of the PDP while effectively using the rear part of the sustain electrode, which has been a non-discharge area, as a discharge space. In particular, if the first color is blue, the white color temperature can be improved.
