The display side surface of the vertical wall 15a of the partition wall 15 is not in contact with the protective layer 12 (see FIG. 4), and a gap r is formed therebetween. The protective layer 12 is in contact with the portion of the protective layer 12 that covers the raised dielectric layer 11A (see FIGS. 2 and 5), and the space between the protective layer 12 and the discharge space S adjacent in the column direction is shielded.

The vertical wall 15a of the partition wall 15 facing the discharge space S
On the side surface of the horizontal wall 15b and on the surface of the dielectric layer 14, phosphor layers 16 are formed in order so as to cover all five surfaces. The color of the phosphor layer 16 is set such that the R, G, and B colors are arranged in the row direction in each discharge space S. A rare gas is sealed in the discharge space S.

In the above-mentioned PDP, the row electrode pairs (X, Y) each constitute one display line (row) L of the matrix display screen, and the discharge spaces S defined by the grid-shaped partition walls 15 are respectively formed. One discharge cell C is defined.
Image display in this PDP is performed in the same manner as in a conventional PDP. That is, first, by an address operation, a discharge is selectively performed between the row electrode pair (X, Y) and the column electrode D in each discharge cell C, and the lit cells (the dielectric layer 11 The discharge cells C on which wall charges are formed) and the light-off cells (discharge cells C on which no wall charges are formed on the dielectric layer 11) are distributed on the panel in accordance with the image to be displayed.

After this address operation, a sustaining pulse is alternately applied to the row electrode pairs (X, Y) simultaneously in all the display lines L. Each time the sustaining pulse is applied, each lighting is turned on. Surface discharge occurs in the cell. As described above, the ultraviolet rays are generated by the surface discharge in the lighting cell, and the R, G, B phosphor layers 16 in the discharge space S are formed.
Are excited and emit light, thereby forming a display screen.

In the above-mentioned PDP, in each discharge cell C, the phosphor layer 16 has five surfaces of the display side surface of the dielectric layer 14 covering the four side walls of the partition wall 15 facing the discharge space S and the column electrode D. , The surface area of the phosphor layer 16, that is, the light emitting area is enlarged as compared with the conventional PDP.

As a result, the brightness per discharge cell C is increased, and the brightness of the display screen can be improved as compared with the prior art. On the other hand, each discharge cell C can be improved in order to increase the definition of the screen. Even if the size of C is reduced, the brightness of the display screen does not decrease as compared with the conventional one.

Further, in the PDP, the transparent electrodes Xa and Ya of the row electrodes X and Y extend from the bus electrodes Xb and Yb to the mating row electrodes, respectively, and form an island shape for each discharge cell C. Even if the size of each discharge cell C is reduced in order to increase the definition of the screen, the interference of the discharge to the adjacent discharge cells C in the display line L direction (horizontal direction) because of the independent configuration. Does not occur.

Further, the PDP is a dielectric layer 11
A raised dielectric layer 11A is formed on the upper surface, and a protective layer 12 covering the raised dielectric layer 11A is
And the discharge spaces S of the adjacent discharge cells C in the column direction (vertical direction) are shielded from each other (see FIGS. 2 and 5), so that the discharge cells adjacent in the column direction The occurrence of discharge interference between C is prevented.

On the other hand, the display side surface of the vertical wall 15a of the partition wall 15 is opposed to the portion of the dielectric layer 11 where the raised dielectric layer 11A is not formed. Since the gap r is formed between the protective layer 12 and the protective layer 12 (see FIGS. 3 and 4), the discharge spaces S of the discharge cells C adjacent to each other in the row direction (display line direction) are slightly spaced through the gap r. When connected, a priming effect that causes a discharge to occur in a chain is generated, and the discharge operation can be stabilized.

Further, the PDP has bus electrodes Xb, Y
By providing the black conductive layers Xb ′ and Yb ′ on the display surface side of b, reflection of external light entering through the front glass substrate 10 is prevented, and the contrast of the display screen is improved. Can be done.

Further, the above PDP is made of a back glass substrate 1
The light emitted by the phosphor layer 16 is reflected toward the display side and is prevented from escaping to the rear side by the white color of the dielectric layer 14 formed on the third layer 3, so that the display screen can be displayed. Brightness can be increased. The dielectric layer 14 serves as a protective layer at the time of sand blast. Further, the PDP has a black layer 15 ′ formed on the display side surface of the partition wall 15,
External light incident through the front glass substrate 10 is prevented from being reflected, and the contrast of the display screen can be improved.

Since the four wall surfaces of the partition wall 15 that divide the discharge space S are constituted by the white layer 15 ″, the light emitted by the phosphor layer 16 is reflected to the display side,
The brightness of the display screen can be increased. Next, a second example of the embodiment of the present invention will be described with reference to FIG.

FIG. 6 is a plan view schematically showing the relationship between the row electrode pairs of the PDP and the barrier ribs in the second example. In the PDP of the second example, the row electrodes X and Y of the PDP in the first example of FIGS. 1 to 5 are alternately arranged in the column direction, whereas the display lines Li, Li arranged in the column direction are arranged.

And Xai + 1 are connected to a common bus electrode Xbj.

Thus, the PDP in the second example is
In adjacent display lines, the row electrodes Xi and Xi + 1 arranged back to back share a bus electrode Xbj, and the installation area of this bus electrode Xbj is
Is smaller than the installation area of the bus electrode of the PDP.

Therefore, the partition wall 2 facing the bus electrode Xbj
5 can be made smaller than the width of the PDP shown in FIGS. 1 to 5, and the volume of the discharge space S1 can be increased accordingly.
Since the surface area of the phosphor layer formed in the discharge space S1 can be increased, the brightness of the display screen is increased. Furthermore, the discharge current can be reduced by sharing the bus electrode Xbj. Note that, in this example, the base ends of the respective transparent electrodes of the row electrodes Xi and Xi + 1 arranged adjacent to each other on the adjacent display lines are connected,

With the above arrangement, the transparent electrodes Xai-1 'and Xai' of the row electrodes Xi-1 'and Xi' which are arranged back to back (in display lines adjacent in the column direction) are common.

As described above, the PDP in the third example is
In adjacent display lines, row electrodes Xi 'and Xi + 1' arranged back to back share bus electrode Xbj ', and row electrodes Yi "and Yi + 1 arranged back to back to each other. 'Shares the bus electrode Ybj', the installation area of the bus electrodes Xbj 'and Ybj' becomes smaller than the installation area of the bus electrode of the PDP in FIG.

Therefore, bus electrodes Xbj 'and Ybj'
The width of the horizontal wall 25b 'of the partition wall 25' facing each other can be further reduced as compared with the PDP of FIGS. 1 to 5, and accordingly, the volume of the discharge space S1 'is increased, and the width of the discharge space S1' is increased. Since the surface area of the phosphor layer can be further increased, the brightness of the display screen is increased.
Furthermore, the discharge current can be reduced by sharing the bus electrodes Xbj ′ and Ybj ′.

In this example, as shown in FIG. 8, in the adjacent display lines, the transparent electrodes Xai-1 ′ of the row electrodes Xi-1 ′ and Xi ′ arranged back to back with each other.
And Xai 'are connected to each other to form a single unit, and further, the row electrodes Yi' and Yi + 1 'are connected to each other to form the transparent electrodes Yai' and Yai + 1 '. It may be formed integrally.
