Are provided on the rear glass substrate 21, the address electrode A as a column electrode, the insulating layer 24, the partition wall 29 for partitioning the discharge space 30, and the phosphor layer 28 for color display.
R, 28G, and 28B are provided. Main electrode Xj, Y

As shown in FIG. 8, each partition wall 29 is waving at a constant cycle and amplitude in a plan view, and the adjacent partition wall 29 has
Are periodically arranged to be smaller than a certain value along the column direction. The constant value is a dimension capable of suppressing discharge, and is determined by discharge conditions such as gas pressure.
Since the partition walls 29 are arranged apart from each other, the space (column space) 31 between adjacent partition walls is continuous across all rows of the screen. Thereby, it is possible to facilitate driving by priming in units of rows, to make the printing state of the phosphor layer uniform, and to facilitate exhaust processing in manufacturing. In the PDP 9, the R (red) phosphor layers 28R, G
(Green) phosphor layer 28G and B (blue) phosphor layer 28
B is arranged in the order of RGB for each color in each column. The emission color of each row in the column is the same.

割合が小さいので、高輝度の表示を行うことができる。Here, in the column space 31, a portion (narrow portion) 31 B having a small width in the row direction is unlikely to generate surface discharge.
The wide portion (large portion) 31A substantially contributes to light emission. Therefore, cells as display elements are arranged every other column in each row. When attention is paid to two adjacent rows, the columns in which the cells are arranged are alternately switched every column. That is, the cells are arranged in a staggered manner in both the row direction and the column direction. In PDP9, adjacent RGB
One pixel is composed of a total of three cells, and the arrangement of three colors for color display is a triangular (delta) arrangement. In the triangular arrangement, the width of the cells in the row direction is larger than 1/3 of the pixel pitch, which is advantageous for higher definition than the in-line arrangement. In addition, since the ratio of the non-light-emitting area of the screen is small, high-luminance display can be performed.

が大きいという問題もあった。In the conventional structure, the shape of the main electrodes Xj and Yj in plan view is a linear band having a constant width over the entire length of the screen, and the narrowed portion 31B of the row space 31 is the same as the wide portion 31A. The main electrodes Xj and Yj were close to each other. For this reason, there is a possibility that erroneous discharge may occur in the constricted portion 31B, and there is a problem that an operation margin is reduced if the erroneous discharge is reliably prevented by setting the drive voltage. There is also a problem that wasteful power consumption required for charging the capacitance between the electrodes is large.

他の目的は、電極間の静電容量を低減することにある。
さらに他の目的は、発光効率を高めることにある。In the wide part 31A, the discharge spreads from the surface discharge gap to the narrow part 31B, whereas the light emitted by the widened discharge is shielded by the metal film 42j, resulting in low luminous efficiency. There was also a problem. SUMMARY OF THE INVENTION It is an object of the present invention to more reliably prevent discharge interference between rows without reducing an operation margin.
Another object is to reduce the capacitance between the electrodes.
Still another object is to increase the luminous efficiency.

This is the same as the PDP 1 of the embodiment. In the PDP 4, the main electrodes Xd and Yd also include a metal film 42d serving as a bus extending over the entire length of the screen in the row direction and a plurality of transparent conductive films 41d serving as strip-shaped branches. Transparent conductive film 41d
Extend obliquely to the row direction over two adjacent rows. In each of the large portions 31A, the transparent conductive film 41d of the main electrode Xd and the transparent conductive film 41d of the main electrode Yd adjacent to the main electrode Xd come close to each other to form a surface discharge gap g4. The positions of the adjacent transparent conductive films 41d are shifted in both the row direction and the column direction, and the gap direction Mg of the surface discharge gap g4 is a direction inclined with respect to both the row direction and the column direction. Since the surface discharge is difficult to spread in the column direction instead of the gap direction Mg in the column direction, the surface discharge
It does not spread to the stenosis 31A concentrated around the center of A.
In addition, as compared with the case where the gap direction Mg is the row direction or the column direction, the length of the opposing line between the adjacent transparent conductive films can be increased, and the discharge probability can be increased and the display can be stabilized.
