極とは直交に配置され放電動作を制御するものである。(Prior Art) Discharge display devices perform luminescent displays using gas discharge, and have excellent features such as highly nonlinear discharge characteristics, high-speed response, and memory performance. It is attracting attention as a means of realizing flat displays with large display capacities. Many monochrome plasma displays based on red-orange emission of Ne have already been used in laptop computers and the like, and there is a strong desire for color displays. The color emission of plasma display is
This can be achieved by generating ultraviolet light using a discharge gas mixed with Xe and converting it into visible light such as red, green, or blue light using a phosphor coated on the inner surface of the discharge cell. Although there are several types of such discharge display devices, an AC-driven surface discharge type discharge display device is known as one particularly suitable for color display. FIG. 4 shows the cell structure of a typical color display surface discharge display device. Glass substrate (

ィの実現が期待されている。Sustaining discharge for luminescent display is performed by applying an alternating current pulse between the surface discharge electrodes 2 and 2". In addition to the structure shown in FIG. 4, the surface discharge type has a trigger electrode with a number of surfaces t.
(w) There are those that are formed on the same substrate with an electrode and an insulating layer interposed therebetween, and those that have no trigger electrode and are composed only of surface discharge electrodes. As can be seen from FIG. 4, in such a surface discharge type display device, since the phosphor layer 6 is located away from the discharge area by the surface discharge electrode, the phosphor is less likely to deteriorate due to plasma damage. Furthermore, the surface discharge type has superior memory performance compared to the general facing electrode type, and maintains a wide memory margin even in the high frequency range. Taking advantage of these advantages, surface discharge type display devices are expected to realize color displays with a large display capacity.

It became expensive and could not be put to practical use. The cause of this is that the dielectric layer is sputtered, and in particular, it was found that the dielectric layer on the edge portion of the surface discharge electrode was sputtered violently. The object of the present invention is to eliminate sputtering at the edge portion of the surface discharge electrode and to extend the life of the surface discharge electrode.

。この様に電界集中とＸｅガス使用のために面放電電極
のエツジ部近傍の誘電体層表面を激しくスパッタする。(Function) In the surface discharge type electrode structure, a very large electric field concentration occurs at the edge portions of opposing electrodes. Also, for color displays, Xe gas is used to generate ultraviolet rays.
Xe has a large mass and is easily sputtered compared to Ne and the like. In this manner, the surface of the dielectric layer near the edge of the surface discharge electrode is sputtered vigorously to concentrate the electric field and use the Xe gas.
誘電体層は一般的にはガラス層とＭｇＯからなる保護層
からなっている。このＭｇＯ層は２次電子放射率が大き
く、放電電圧の低減に大きく寄与しているものである。The dielectric layer generally consists of a glass layer and a protective layer made of MgO. This MgO layer has a high secondary electron emissivity and greatly contributes to reducing the discharge voltage.

部分が電極面積に対して非常に狭くても、放電特性を悪
化させてしまう。The reason why the voltage necessary for discharging a surface discharge display becomes high in a short operating time is that the MgO layer near the edges is damaged by sputtering. In the surface discharge type, the characteristics of the electrode edge portion dominate the overall characteristics, and even if the edge portion to be sputtered is extremely narrow relative to the electrode area, the discharge characteristics will deteriorate.

合に比較して大巾に低減することができる。The present invention aims to prevent sputtering and improve life by alleviating electric field concentration at the edge portion. Specifically, a floating electrode is provided along the surface discharge electrode. Various shapes can be considered for the floating electrode, but it is best to place a thin wire-shaped floating electrode on a single sheet of paper a little apart from the edge of the surface discharge electrode. When a voltage is applied to the surface discharge electrode, a potential is also induced in the floating electrode due to capacitive coupling. Therefore, the maximum electric field intensity due to electric field concentration at the surface discharge electrode edge or floating electrode edge portion can be significantly reduced compared to the case where there is no floating electrode.

初期の短い時間だけ放電が発生するために、上述のよう
に面放電電極エツジ部に高抵抗部分を沿設することによ
りエツジ部の電界集中を動的に緩和することができる。Another method is to provide a high-resistance electrode section along the edge of the surface discharge electrode. When a pulse voltage is applied to the surface discharge electrode, since the surface discharge electrode has a low resistance, the potential rises instantaneously at the edge portion, which has a high resistance and therefore has a slow rise due to the time constant of CR. In an AC drive type in which a dielectric layer is formed on the electrode display, discharge occurs only for a short period of time when voltage is applied, so it is necessary to place a high resistance part along the edge of the surface discharge electrode as described above. This makes it possible to dynamically alleviate electric field concentration at the edge.
このため浮遊電極を付けた場合と同様にスパッタが低減
され、寿命が改善される。As a result, spatter is reduced and the life span is improved in the same way as when a floating electrode is attached.

ジンは非常に大きいために実用上の問題はない。As a result of the measures taken to alleviate electric field concentration at the edge of the surface discharge electrode of the present invention, a decrease in the memory margin calculated from the ignition voltage and sustaining voltage was observed. Since electric field concentration at the edges is the cause of the large memory margin of the surface discharge type, it seems natural that the memory margin will decrease as the electric field concentration eases, but the memory margin of the surface discharge type is originally very large. There is no practical problem due to its large size.

見られた。(Embodiment) A large embodiment of the present invention will be described with reference to a sectional view of a dog. A surface discharge electrode 2.2' and floating electrodes 9, 10, 9' and 10' are formed on a glass substrate (1) 1, and a 15 micron thick glass layer and a 1 micron thick MgO
A dielectric layer 3 consisting of layers is formed. The glass layer was formed by screen printing, and the MgO layer was formed by vacuum deposition. The partition walls 7 having a height of about 150 microns are formed by multilayer coating using screen printing. A trigger electrode 5 made of a transparent conductive film and a phosphor layer 6 coated with phosphor powder are formed on the glass substrate (II). A He-Xe mixed gas containing 1% of Xe was used as the discharge gas. The diameter of the surface discharge electrodes was 150 microns, and the distance between the pair of surface discharge electrodes 2.2' was 150 microns. Floating electrode 9.10,
The width of the electrode 10' was 15 microns, and the distance between the surface discharge electrode 2 and the floating electrode 9 and between the floating electrode 9 and the floating electrode 10 was 10 microns. These electrodes are fine and made of metal thin films such as AI using photolithography technology. The ignition voltage at which discharge starts and the sustaining voltage at which discharge stops in this discharge display device were 203v and 160v, respectively. In a conventional surface discharge type with the structure shown in FIG. 1 and without a floating electrode, the ignition voltage was 200V and the sustaining voltage was 150V. Inserting the floating electrode slightly increased the operating voltage and lowered the memory margin, but the value was still more than sufficient for practical use. FIG. 3 shows how the sustaining voltage changes in an accelerated aging test driven at 100 KHz. In the conventional surface discharge type shown by the broken line, the sustaining voltage and ignition voltage began to rise after about 500 hours, whereas in this example with a floating electrode, the sustaining voltage hardly changed until 5000 hours. An improvement in the life characteristics was seen in the non-woven fabric.

状もドツト状等の変形したものとしても良い。Although this embodiment has a structure in which two linear floating electrodes are arranged on the surface discharge electrode side, the number of floating electrodes may be one or three or more. The larger the number, the greater the effect of alleviating electric field concentration, which is good for improving lifespan, but the discharge characteristics such as memory margin deteriorate. Furthermore, the floating electrode width, spacing, etc. may be designed in accordance with the required specifications of discharge characteristics and life characteristics, and there is no need to be particular about the dimensions of this embodiment. Further, the shape may be modified such as a dot shape.

After forming a high-resistance thin film of 0.1 μm thick made of an alloy of i and Ge, 0.5 μm of Cu and 0.01 μm of Cr are formed thereon.

しまう。This low electrical resistance portion mainly composed of Cu corresponds to the surface discharge electrode 11.1F. The high-resistance thin film of Si and Ge alloy has a sheet resistance of approximately 500 MΩ, and is patterned to protrude by 70 microns from the edge of the surface discharge electrode 11.11', forming a high-resistance edge portion 12.12'. . Such a shape can be easily obtained by performing photolithography twice. As a result of continuous operation of this discharge display device at 100 KHz, approximately 300
No increase in ignition voltage or maintenance voltage was observed up to 0 hours, and the life characteristics were improved. Note that if the resistance value of the high-resistance edge part is too large, it will not be useful as a high-resistance edge part and sputtering will become severe near the end of the surface discharge electrode 11.11''.Also, if the resistance value is too small In this case, sputtering becomes intense at the ends of the high-resistance edge portions 12, 12'.

ミクロン程度が好ましい。Therefore, the sheet resistance value of the high resistance edge portion is preferably about 105Ω to 1011Ω. In addition, if the length of the high-resistance edge part is too short, the electric field concentration relaxation effect will be small, and if it is too long, the discharge characteristics will deteriorate.
Preferably, it is on the order of microns.
