Further, the scanning electrodes 1 and the common electrodes 2 are arranged in parallel along the row direction H of the screen, and alternately protrude on the strip-shaped partition walls 3 toward the center of the unit cell 15.

The scanning electrode 1 and the common electrode 2 are, for example,
The scanning electrode 1 and the common electrode 2 are made of metal electrodes such as copper, silver, and aluminum, and are covered with a dielectric layer 7a made of zinc-containing frit glass, lead-containing frit glass, or the like. Then, the dielectric layer 7a is covered with a protective layer 8 made of, for example, MgO (magnesium oxide).

Examples of the ultraviolet generating gas include a mixed gas of Ne and Xe, He
And a mixed gas of Ne and Xe.

According to the above-described structure, since the dielectric layer 7a and the transparent electrode 13 used in the conventional plasma display panel are not provided in the unit for extracting visible light in the unit cell 5, the visible light transmittance is reduced. The brightness can be improved.

Since there is a space in the path for charging and discharging the capacitance between the scanning electrode 1 and the common electrode 2 in the unit cell 5, the capacitance between the electrodes is low and the charging / discharging current can be reduced. As a result, the reactive power can be reduced.

The scanning electrode 1 and the common electrode 2 are 1,
2,1,1,2,1,1,2,1, ..., 1,2,1
, The distance of the non-discharge gap 16 required for the conventional plasma display panel can be shortened, the aperture ratio can be improved, and the applied voltage is the same between the unit cells 5 in the column direction V. Discharge current can be reduced, and reactive power can be reduced.

Further, since the scanning electrode 1 and the common electrode 2 are provided so as to have a height of 50 to 200 μm, the wall charges required for the sustain discharge can be sufficiently accumulated.

Since the scanning electrode 1 and the common electrode 2 are not formed in the partition 3, the phosphor layer 9 can be formed without reducing the application area.

Furthermore, since the light-shielding projections of the scanning electrode 1 and the common electrode 2 are arranged above the partition walls 3 which do not contribute to light emission, external light can be absorbed and the contrast can be improved.

The range of the electrode height was determined based on the following grounds. In other words, the current plasma display panel production process is performed at about ± 5 μm with respect to the design dimensions. When a 30-inch HDTV-sized plasma display panel is produced by the current production process, the electrode area (display electrode pair One area, for example, the area of the portion that does not overlap the partition 3 in the unit cell 5 of 13a) is about 6800 μm ² . In order to secure this area with the electrode of the present invention, the height is about 65μ.
m is required. In the case of a 50-inch XGA size plasma display panel, the electrode area is about 43000 μm ² . In order to secure this area with the electrode of the present invention, a height of about 120
μm is required. When the electrode area is reduced, the light emission characteristics are reduced, and therefore the lower limit is considered to be 50 μm in height. Also, as the electrode area increases, the emission characteristics improve,
It is thought that the upper limit is 200 μm in height, which is a value that can be created on the current creation process. More preferred range is height 65-150
μm, particularly preferably a height of 70 to 125 μm (30-inch HDTV to
(When considering a 50-inch XGA).

In the first embodiment described above, five modifications are shown, but those modifications also apply to the second embodiment.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and the design may be changed without departing from the gist of the present invention. The present invention is also included in the present invention.

For example, the arrangement of the protruding portions of the scanning electrode 1 and the common electrode 2 is not particularly limited in the present invention, and 1, 2, 1, 2 in the row direction H of the screen as in this embodiment. ,... May be replaced in the order of 2, 1, 2, 1,... In each row. Further, the shape of the partition wall 3 is not particularly limited in the present invention, and may be a cross-girder shape other than the band shape as in the present embodiment.

[0069]

As described above, according to the structure of the plasma display panel of the present invention, since the transparent electrode and the dielectric layer are not laminated at the portion where the visible light is extracted in the unit cell, the visible light transmittance is reduced. Therefore, the aperture ratio can be greatly improved because of the structure in which the distance of the non-discharge gap can be reduced. Accordingly, a plasma display panel having improved luminance is provided.

Since the scanning electrode and the common electrode have a height of 50 to 200 μm, a plasma display panel capable of sufficiently accumulating wall charges required for sustain discharge is provided.

Further, there is a space in a path for charging and discharging the capacitance between the scanning electrode and the common electrode in the unit cell,
Since the applied voltage is the same between the unit cells in the column direction, the capacitance between the electrodes is low, the charge / discharge current can be reduced, and the plasma display panel can be reduced in reactive power.

Further, since no electrode is formed on the partition wall portion, the phosphor layer can be formed without reducing the application area of the phosphor. Since the protective layer and the substrate on which the phosphor layer is formed are different, the protective layer is formed on the phosphor layer. There is provided a plasma display panel which is not formed and does not lower the excitation light emission efficiency of the phosphor.

Furthermore, since the light-shielding projections of the scanning electrode and the common electrode are arranged above the partition walls that do not contribute to light emission, a plasma display panel capable of absorbing external light and improving contrast can be provided.
