Since it is arranged so that it can be seen through the film, it has a drawback that the light transmittance is poor. Moreover, since the ITO film has poor conductivity, it is necessary to apply a high voltage to the discharge electrode when increasing the discharge current in order to increase the emission intensity. Therefore, the conventional plasma display panel using the ITO film has a drawback of high power consumption. Further, the printing method and the sandblast method for forming the barrier ribs, and the photolithography method for forming the discharge electrode have an extremely large number of processing steps, and conventionally, the barrier rib and the discharge electrode are separately formed. Therefore, the conventional plasma display panel has a drawback that the manufacturing cost is high. Therefore, an object of the present invention is to provide a plasma display panel and a method of manufacturing the same, which does not use a transparent electrode such as an ITO film as a discharge electrode and which is lower in manufacturing cost than conventional ones.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to illustrated embodiments. In FIG. 1, reference numeral 1 is a plasma display panel. This plasma display panel 1 is
A front panel 2 on the front side, a rear panel 3 on the back side, and a large number of partition walls 4 provided in parallel between the two panels 2 and 3 in the X direction in the drawing. Both the front panel 2 and the rear panel 3 are made of transparent resin (for example, PET, polyimide) and have flexibility. The partition walls 4 of this embodiment are formed in a thin plate shape with a transparent resin (for example, PET or polyimide) mixed with a phosphor, and are arranged at predetermined intervals in the Y direction parallel to the X direction and orthogonal to the X direction. is doing. The width of the bottom of the partition wall 4 (dimension in the Y direction) is slightly larger than the width of the top (dimension in the Y direction) and is trapezoidal. Each partition wall 4 is provided so as to stand upright on the surface of the rear panel 3. A large number of elongated discharge spaces 5 parallel to the X direction are defined by the partition walls 4 and the panels 2 and 3. A discharge gas is enclosed in these discharge spaces 5.

A linear Y-direction electrode 6 is provided on the rear panel 3 facing each of the discharge spaces 5 in parallel with the Y-direction. These Y-direction electrodes 6 are made of thin copper foil and are arranged at equal intervals in the X-direction. Each Y direction electrode 6
This constitutes a preliminary discharge electrode. The partition wall 4 is
The Y-direction electrodes 6 are provided so as to be orthogonal to each other, and the bottom surface of each partition wall 4 is superposed on and closely adhered to the upper surface of the rear panel 3 and each Y-direction electrode 6. On the other hand, unlike the conventional one,
In this embodiment, an X-direction electrode 7 orthogonal to the Y-direction electrode 6 is provided on the top of each partition wall 4. This X-direction electrode 7 is also made of a thin copper foil, is integrally provided over the entire length of the top of each partition wall 4, and the X-direction electrode 7 provided on the top of each partition wall 4 is
It is in close contact with the bottom surface (rear side surface) of. The X-direction electrode 7 is composed of two types of electrodes, a main discharge electrode and a GND electrode, and the main discharge electrode and the GND electrode are alternately arranged in the Y direction. The X-direction electrode 7 provided on the top of the partition wall 4 also has a black stripe function. As described above, the phosphor is mixed in each partition wall 4, but in the present embodiment shown in FIG. 1, the X-direction electrode 7 serving as the main discharge electrode has red, green, and The blue phosphor is mixed, and the X-direction electrode 7 serving as the GND electrode is mixed with half of the phosphor of the color mixed in the partition 4 at the adjacent position.

Further, the rear panel 3 provided with the X-direction electrodes 7, the Y-direction electrodes 6 and the respective partition walls 4 in this way is covered with a thin dielectric film 8 over the entire surface. As this dielectric film 8, a SiO ₂ film or a MgO film is used. By thus coating the surface of each partition wall 4 with the dielectric film 8, the surface of the partition wall 4 made of resin can be protected and at the same time discharge concentration can be prevented during AC discharge. The contoured portions of the two panels 2 and 3 are sealed by a not-shown closing member, and the discharge spaces 5 between the panels 2 and 3 are in a sealed state.
The required discharge gas is sealed inside. In the present embodiment, for example, a mixed gas of xenon gas and neon gas or a mixed gas of helium gas, xenon gas and neon gas is used as the discharge gas. Further, in this embodiment, several% of carbon monoxide is mixed in the mixed gas.

In the above structure, a low voltage is applied to a specific electrode of the Y-direction electrode 6 (preliminary electrode) from a power source (not shown) so that the specific electrode and adjacent electrodes sandwiching the specific electrode are adjacent to each other. Pre-discharge. Next, by applying a voltage to a specific electrode of the main discharge electrodes of the X-direction electrode 7, main discharge is performed between the specific main discharge electrode and the GND electrode adjacent to the specific main discharge electrode at the location where preliminary discharge is performed. At this time,
The voltage applied to the Y-direction electrode 6 (preliminary electrode) is smaller than the voltage applied to the main electrode of the X-direction electrode 7. Then, the discharge gas in the discharge space 5, which is located adjacent to the intersection of the specific Y-direction electrode 6 and the X-direction electrode 7, is in a discharge plasma state to generate ultraviolet rays. The ultraviolet rays cause the phosphors mixed in the partition walls 4 to emit light to emit required visible light. At this time, in this embodiment, since carbon monoxide is mixed in the discharge gas, when visible light is emitted, orange emission is suppressed and the brightness of the display color is increased. . As described above, in the present embodiment, the X-direction electrode 7 is provided integrally with the partition wall 4 on the top of the partition wall 4, and the ITO film is not provided on the lower surface of the front panel 2 facing each discharge space 5. Therefore, the emission brightness is higher than that of the conventional one.
In addition, in this embodiment, since the ITO film is not used as the discharge electrode and copper having good conductivity is used, it is not necessary to apply a high voltage to the X-direction electrode and the Y-direction electrode, and the power consumption is smaller than in the conventional case. The plasma display panel 1 can be provided. Moreover, in this embodiment, since both panels 2 and 3 are made of transparent resin, it is possible to provide the plasma display panel 1 in which the internal configuration can be visually observed from the outside, unlike the conventional case. In addition, as a material of both panels 2 and 3 in the above-mentioned embodiment,
Soda lime glass may be used instead of the resin (PET). Furthermore, the present embodiment can provide the bendable plasma display panel 1 by forming both the panels 2 and 3 and the partition wall 4 from a resin having flexibility. Although the phosphor is mixed in the partition wall 4 in this embodiment, the phosphor may be applied to the side surface of the partition wall 4 or the surface of the rear panel 3 as in the conventional case.

--- (Description of Manufacturing Process) Next, the manufacturing process of the plasma display panel 1 of the present embodiment will be described with reference to FIGS. First, as shown in FIG.
A thin plate 11 of transparent resin (PET), which is a material of the rear panel 3, is prepared. On the upper surface (front side surface) of the thin plate 11, a large number of streaky copper foils 12 to be the Y-direction electrodes 6 are attached in advance at predetermined intervals. Next, as shown in FIG. 3, a resin film 13 having a predetermined thickness is attached by thermocompression bonding to the entire upper surface of the thin plate 11 on which the copper foil 12 is provided. Red, green, and blue phosphors are mixed in advance in the resin film 13 in a predetermined width, and the X-direction electrode is previously formed in the entire upper surface (front surface) of the resin film 13. The copper foil 14 to be No. 7 is attached by thermocompression bonding. In the present embodiment, since the thin plate 11 to be the rear panel 3 is made of resin, a thin film of SiO ₂ is applied to the entire surface (upper surface) of the thin plate 11, and the resin film 13 is stuck on the thin film. ing. Next, as shown in FIG. 4, the copper foil 14 located on the surface of the resin film 13 is formed into stripes parallel to the X direction at predetermined intervals by a conventionally known photolithography method. Patterning is performed so that More specifically, first, a resist is applied to the upper surface of the copper foil 14, and then the applied resist is exposed to form a predetermined pattern to cure the resist into a large number of streaks. Then, the copper foil 14 other than the hardened part of the resist is removed by washing. As a result, the copper foil 14
The resist in the region which does not remain as an electrode in is completely removed. Next, chemical etching is performed on the copper foil 14 in this state. By performing this chemical etching, the copper foil 14 in the region where the resist is not attached is entirely removed from the surface of the resin film 13. After that, the resist adhered to the copper foil 14 which remains in a streak shape is completely removed chemically. By patterning the copper foil 14 in this manner, the copper foil 14 to be the X-direction electrode 7 remains in a streak shape on the surface of the resin film 13.

Next, laser etching is performed by irradiating the surface of the resin film 13 and the striped copper foil 14 in this state with CO ₂ laser light (FIG. 5). that time,
Since the striped copper foil 14 functions as a mask, the unmasked resin film 13 located between adjacent striped copper foils 14 is removed (FIG. 6). Further, since the SiO ₂ film is applied to the surface of the thin plate 11 made of resin, laser etching is performed up to the position where this film is applied so that the surface of the thin plate 11 made of resin is not laser-etched. There is. As a result, the resin film 13 in the area masked by the strip-shaped copper foil 14 remains in the strip shape and is formed as the partition wall 4. The partition wall 4 thus formed has a striped shape in which the width of the bottom is slightly larger than the width of the top, and the thin plate 11 is formed.
Is formed in an upright state with respect to the surface of. In addition,
This means that each partition wall 4 contains a phosphor of a predetermined color. In addition, the copper foil 14 attached to the top of the partition wall 4 and remaining
Are formed as the X-direction electrodes 7. Also, the thin plate 11
The copper foil 12 is exposed on the upper surface of the so as to be orthogonal to the partition wall 4, and this becomes the Y-direction electrode 6. next,
As shown in FIG. 7, the entire surface of the rear panel 3 is covered with a SiO ₂ film 8 serving as a dielectric film. As a result, the rear panel 3 having the Y-direction electrode 6 and the X-direction electrode 7 and the partition wall 4 are formed. Next, the back surface of the resin thin plate 15 which becomes the front panel 2 is brought into close contact with the tops (X-direction electrodes 7) of the partition walls 4 on the rear panel 3 (FIG. 8). After that, after supplying the discharge gas into the discharge space 5 between the adjacent barrier ribs 4, both thin plates 11,
The plasma display panel 1 of the present embodiment shown in FIG. 1 is completed by closing the opening of the contour 15 with the closing member.

As described above, according to the method of manufacturing the plasma display panel 1 of this embodiment, the copper foil 14 as a mask patterned to form the partition walls 4 is formed.
Remains as the X-direction electrode 7 on the top of the partition wall 4 as it is, so that it is not necessary to dispose the X-direction electrode on the lower surface of the front panel 2 facing each discharge space 5. Further, in this embodiment, since the ITO film is not used, the step of providing it becomes unnecessary. Then, in this embodiment, the partition wall 4 and the X-direction electrode 7 can be formed by only a few steps. Compared with the conventional method for manufacturing a plasma display panel, which requires a large number of processing steps for forming barrier ribs and mounting X-direction electrodes, the manufacturing cost of the plasma display panel 1 can be significantly reduced according to this embodiment. You can Further, since the material of the partition wall 4 is resin, the resin in the unnecessary region can be easily removed by laser etching. Although resin (PET) is used as the material of both panels 2 and 3 in the above embodiment, soda lime glass may be used instead of resin. As described above, when soda lime glass is used, the SiO ₂ film applied to the surface of the thin plate 11 in the manufacturing process described above can be omitted.

(Second Embodiment) Next, FIG. 9 shows a plasma display panel 1 according to a second embodiment of the present invention. In short, this second embodiment is an upside down arrangement of both panels in the first embodiment. That is, in this embodiment, the partition wall 4 is formed integrally with the front panel 2, and the partition wall 4 facing downward is formed.
The X-direction electrode 7 is provided on the top that is the lower end of the. On the lower surface of the front panel 2 (the surface on the rear side), the Y-direction electrodes 6
Is provided. Then, the X-direction electrode 7 located on the top of each partition 4 is brought into close contact with the upper surface of the rear panel 3. The other structure and the manufacturing process of the plasma display panel 2 of the second embodiment are substantially the same as those of the first embodiment, and the description of the same parts will be omitted. The second of such a configuration
It is obvious that the same action and effect as in the first embodiment can be obtained in the embodiment as well.

The third embodiment is different from the first embodiment in that a partition 4'is also formed on the front panel 2 side at a position facing the rear panel 3 side, and the X-direction electrode 7 provided on the top of the partition 4 of the rear panel 3 is formed. It is a close contact. Since the other structure is the same as that of the first embodiment, the description of the same parts will be omitted. It is apparent that the third embodiment having such a configuration can also obtain the same operation and effect as those of the first embodiment.

The Y-direction electrodes 6 are provided at the positions of the bottoms of the partition walls 4 ′ in each Y-direction, that is, on the surface of the rear panel 3. The width of the Y-direction electrode 6 is formed wider than the width of the bottom portion of the partition wall 4'in the Y-direction. Therefore, both side portions of each electrode 6 in the longitudinal direction are exposed to the discharge space 5 to cause discharge. It faces Space 5. Other configurations and operations are the same as those of the first embodiment. Although the Y-direction electrode 6 is wider than the bottom of the Y-direction partition wall 4 ′ so that both sides in the longitudinal direction face the discharge space 5, the width of the Y-direction electrode 6 is Y-direction partition wall. The width may be set to be the same as the width of the bottom of 4 '.

The copper foil 14 is attached by thermocompression bonding. In the present embodiment, since the thin plate 11 to be the rear panel 3 is made of resin, a thin film of SiO ₂ is applied to the entire surface (upper surface) of the thin plate 11, and the resin film 13 is stuck on the thin film. ing. Next, as shown in FIG. 4, the copper foil 14 located on the surface of the resin film 13 is formed by a conventionally known photolithography method so that the copper foil 14 has a lattice shape parallel to the XY directions. Perform patterning. Next, the surface of the resin film 13 in this state and the copper foil 14 in the form of a lattice are irradiated with CO ₂ laser light to perform laser etching (FIG. 5). At this time, the copper foils 14 remaining in the lattice form function as a mask, whereby the partition walls 4 in the X direction and the partition walls 4'in the Y direction are substantially formed. Then, a resist is applied by screen printing only on the copper foil 14 (X-direction electrode 7) on the partition wall 4 in the X-direction. After that, chemical etching is performed to remove the copper foil 14 remaining on the partition walls 4'in the Y direction.
After that, the resist applied on the copper foil 14 (X-direction electrode 7) on the partition wall 4 in the X direction is removed. Thus, the X-direction partition 4 and the X-direction electrode 7 are formed, and the Y-direction partition 4'and the Y-direction electrode 6 are formed. Subsequent processing steps are the same as those in the first embodiment, so description thereof will be omitted. It is obvious that the fourth embodiment as described above can also obtain the same operation and effect as those of the first embodiment.
