BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel (hereinafter referred to as PDP) of a plasma display device, and more particularly to improvement of a sustain electrode of a surface discharge type plasma display panel.

[0003]

[0002]

[0004]

2. Description of the Related Art In recent years, practical use of a plasma display panel (PDP) as a large and thin color display device is expected.

As is well known, a PDP has a structure in which a pair of electrodes arranged to face each other across a discharge space are provided with electrode groups intersecting with each other, and discharge cells are formed at the intersections of the electrodes to selectively emit light. Has been done.

[0006]

For example, a surface discharge type PD using an AC drive system
In P, a plurality of sustain electrode groups extending in parallel with each other are formed on the inner surface of the substrate on the display surface side, and a dielectric layer, MgO are formed thereon.
The (magnesium oxide) layers are sequentially formed. on the other hand,
Address electrodes are formed in parallel on the back substrate so as to intersect the sustain electrode pairs, phosphors are formed on the address electrodes, and ribs are formed between the address electrodes. The discharge space is filled with a mixed rare gas.

[0007]

In the PDP operation, first, a predetermined voltage is applied between the address electrode and the sustain electrode to start discharge, and then an AC voltage is applied between the pair of sustain electrodes to maintain the discharge. The phosphor layer is excited by the ultraviolet rays generated by this discharge to emit light. Here, the MgO layer is 2
It has a function of increasing the secondary electron emissivity and lowering the discharge start voltage, and is applied so that the polarities of the closest electrode lines are reversed between adjacent scanning lines due to the selectivity of pixels.

[0008]

[0005] In recent years, with the increase in size of PDPs, there has been a demand for higher definition of images in order to improve the image quality.

By the way, in order to increase the number of light-emitting pixels to achieve high definition, it is necessary to narrow the interval between the adjacent sustain electrode pairs. If this happens, erroneous discharge is likely to occur between the adjacent sustain electrode pairs. There was a problem of becoming.

Further, as a countermeasure against this, it is conceivable to increase the thickness of the dielectric between scanning lines, but the number of manufacturing steps is increased, which hinders the miniaturization of pixels.

[0011]

[0006]

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a simple structure, prevents erroneous discharge between adjacent sustain electrode pairs, and performs stable and high-definition display.

A surface discharge type plasma display panel including a magnesium oxide film formed on a surface of the dielectric layer except the surface of the dielectric layer between adjacent sustain electrode pairs. It

[0008]

[0016]

The present invention is constructed as described above.
According to the described invention, M is removed except for the surface of the dielectric layer between the adjacent sustain electrode pairs of the surface discharge plasma display panel.
Since the gO layer is formed, discharge is unlikely to occur between the adjacent sustain electrode pairs in which MgO is not formed, and therefore the discharge start voltage between the adjacent sustain electrode pairs can be increased,
False discharge is suppressed. Therefore, the reliability of the display operation is improved.

[0017]

[0009]

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a PDP according to an embodiment of the present invention.
3 is a schematic perspective view showing the structure of FIG.

In FIG. 1, in the PDP, a pair of front glass substrate 1 and rear glass substrate 2 are arranged to face each other with a discharge space 4 in between, and the inner surface (front glass substrate 2) of the front glass substrate 1 which is the display surface is opposed. A plurality of transparent sustain electrode pairs 3 composed of a transparent electrode 3a and a transparent electrode 3b made of a transparent conductive film and a bus electrode 3c made of a metal film for compensating the conductivity of the transparent conductive film are formed on the surface). The scanning lines of the PDP are arranged in parallel with each other.

[0020]

Each sustain electrode pair 3 is configured to form a discharge gap 5 which is the center of each light emitting region, and a bus electrode 3c is formed along the longitudinal direction because the transparent electrode has a relatively high electric resistance. There is.

The bus electrodes 3c are formed on the transparent electrode 3a and the transparent electrode 3b, respectively.
And is provided on the edge of the sustain electrode pair 3 on the opposite side of the discharge gap 5. Further, a dielectric layer 6 made of low melting point glass is formed on the inner surface side of the bus electrode 3c.
Are formed and are further connected to the internal space 4 via the MgO layer 7 formed on the dielectric layer 6.

[0022]

On the other hand, on the inner surface side of the back glass substrate 2 on the opposite side, a plurality of transparent sustain electrode pairs 3 are intersected with each other, and a plurality of transparent sustain electrode pairs 3 are arranged at a predetermined interval by a discharge space 4. A plurality of address electrodes 8 are formed in parallel with each other. A phosphor layer 9 is formed so as to cover this. The phosphor layer 9 is formed of a set of a red light emitting body 9a, a green light emitting body 9b, and a blue light emitting body 9c on three adjacent address electrodes 8.

[0023]

A partition wall (rib) 10 having a predetermined height is formed between the address electrodes 8 on the rear glass substrate 2 to partition the intersecting address electrodes 8 and bus electrodes 3c. A discharge cell which becomes a pixel having a light emitting surface with a predetermined area is formed. The phosphor layers 9 are formed between the partition walls (ribs) 10. The discharge space 4 is closed and formed by a front glass substrate 1 having a plurality of sustain electrode pairs 3 and a rear glass substrate 2 having a plurality of address electrodes 8 having a plurality of sets of phosphor layers 9. . Further, the discharge space 4 is filled with a discharge gas (not shown) in which, for example, neon is mixed with xenon.

[0024]

Further, FIG. 2 shows P in one embodiment of the present invention.
FIG. 6 is a cross-sectional structural view of an MgO layer formed by DP, which is shown in a direction along an address electrode of PDP.

In the figure, the MgO layer 7 is patterned on the dielectric layer 6 except for the regions 11 facing each other between a plurality of adjacent sustain electrode pairs 3.

[0026]

In the present invention, the discharge cells are extremely finely formed, and therefore, the space between the adjacent sustain electrode pairs 3 is narrow, and therefore the region 11 facing between the sustain electrode pairs 3 is also finely formed. The MgO layer 7 is patterned on the dielectric layer 6 by the wrist-off method or the like, so that the number of manufacturing steps is small and the miniaturization is easy.

The PDP in one embodiment of the present invention is configured as described above.

[0028]

Next, how each discharge cell of the PDP in one embodiment of the present invention emits light will be described. First, in FIG. 2, a predetermined voltage is applied between the address electrode 8 and the sustain electrode pair 3 to start discharge.

[0029]

After that, a sustaining pulse by an AC voltage is applied between the transparent electrode 3a and the transparent electrode 3b of the sustaining electrode pair 3, and the discharge is maintained in the discharge gap 5. 2 in the dielectric layer 6 near the discharge gap 5 where the discharge is maintained.
Secondary electrons are emitted to the discharge space 4 via the MgO layer 7.
Here, the MgO layer 7 has the functions of increasing the secondary electron emissivity and decreasing the discharge start voltage, and the emitted secondary electrons are emitted from the phosphor layer 9 (in FIG. 2) formed on the facing address electrode 8. , The red light emitter 9a) is caused to emit light.

[0030]

At this time, the voltage is applied so that the polarities of the closest electrode lines are reversed between adjacent scanning lines due to the selectivity of the pixel, but the dielectric layer 6 is a portion where the MgO layer 7 is formed. Since secondary electrons are less likely to radiate in the portion where the region 11 where the MgO layer 7 is removed is formed, discharge does not occur in the vicinity of the region 11 that corresponds between adjacent sustain electrode pairs. Therefore, even if a space between adjacent scan lines of the sustain electrode pair 3 is narrowed to form a fine discharge cell, no erroneous discharge occurs and stable light emission display can be performed.

[0031]

On the surface of the dielectric layer, the MgO layer is formed not only in the region corresponding to the space between the adjacent sustain electrode pairs, but also in the region corresponding to the bus electrode and / or the region corresponding to the bus electrode as shown in FIG.
Alternatively, as shown in FIG. 4, the region corresponding to the partition wall (rib) may be removed.

As a result, erroneous discharge between adjacent sustain electrodes can be prevented more reliably, and unnecessary spread of discharge can be suppressed.

FIG. 3 shows P in another embodiment of the present invention.
FIG. 6 is a cross-sectional structural view of an MgO layer formed by DP, which is shown in a direction along an address electrode of PDP.

FIG. 4 is a sectional view of the MgO layer of the PDP in another embodiment of the present invention.
It is shown in a direction orthogonal to the address electrode of DP.

[0035]

[0019]

[0036]

Since the present invention is configured as described above, according to the invention of claim 1, the MgO layer is formed except the surface of the dielectric layer between the adjacent sustain electrode pairs of the surface discharge type plasma display panel. Since it is formed, the discharge is unlikely to occur between the adjacent sustain electrode pairs in which MgO is not formed, and therefore the discharge start voltage between the adjacent sustain electrode pairs can be increased and erroneous discharge is suppressed. Therefore, the reliability of the display operation is improved.
