[Problems to be solved by conventional techniques and devices]

 A commonly used conventional surface discharge plasma display panel will be described below with reference to FIGS. 7 and 8. That is, FIG. 7 is a view showing a conventional two-dimensional surface discharge type plasma display panel. As shown in the drawing, X electrodes 2 are arranged on a glass substrate 1 and dielectrics 3 are arranged on the X electrodes 2. After coating, the Y electrodes 4 are further arranged. Then, the MgO layer 6 is formed in a state where the second dielectric 5 is applied, the discharge space 7 is formed on the MgO layer 6, and the upper glass plate 8 is arranged on the discharge space 7. It is composed by

In such a conventional surface discharge plasma display panel, the panel is limited to a thickness of 15 μm to 50 μm of the dielectric 3 corresponding to the intersection between the X electrode 2 and the Y electrode 4. However, dielectric breakdown may occur at this portion, and if the thickness of the dielectric 3 is increased in order to prevent the breakdown, there is a drawback that the brightness is lowered and erroneous discharge is caused. FIG. 8 is a view showing a conventional three-dimensional surface discharge type plasma display panel. As shown in the drawing, an X electrode 12 and a Y electrode 13 are arranged on a glass substrate 11 in the same plane. A dielectric 14 is applied on the electrodes 12 and 13. A third electrode 15 is arranged on the dielectric 14, a MgO layer 16 is formed on the electrode 15, and a discharge space 17 and an upper glass plate 18 are provided thereon. The planar electrode array of such a three-dimensional surface discharge type plasma display panel is as shown in FIG. In between, a potential distribution as shown by a dotted line 19 in FIG. 2B is formed.

When an opposite potential is applied to the Y electrode 13, a potential distribution as shown by a dotted line 20 is formed between the Y electrode 13 and the X electrode 12. Therefore, the conventional three-dimensional surface discharge plasma display panel also has a drawback that dielectric breakdown occurs in a part of the dielectric, and the X electrode 12 and the Y electrode 13 are arranged in parallel on the same plane. There is a problem in that high resolution cannot be obtained.

Therefore, in order to solve such a problem, an object of the present invention is to obtain a high-resolution plasma display panel.
