The present invention defines a method for manufacturing a cover substrate 6 which becomes the light emitting panel portion of a surface discharge type gas discharge panel that emits light by stimulating a phosphor therein.
本発明はカラー表示面放電形ガス放電パネルの製造方法
であって、将来の壁掛はテレビに代表される新規なカラ
ー化平面ガス放電パネルに利用される。The present invention is a method of manufacturing a color display surface discharge type gas discharge panel, which will be used in future wall hangings for new colorized flat gas discharge panels typified by televisions.
その池水薄形パネルは、近未来における奥行きの少ない
コンパクトなカラー表示可能情報表示パネルとして実現
を強く要望されている。There is a strong demand for the Ikemizu thin panel to be realized as a compact color information display panel with little depth in the near future.
カラー表示を行う面放電形ガス放電パネルとして従来第
３図に断面を示すようなパネルを製作していた。Conventionally, a surface discharge type gas discharge panel for displaying color has been manufactured, the cross section of which is shown in FIG.
第３図において、１０は電極基板、Ｘ、Ｙは表示電極対

ー基板、８０は螢光体、９０はスペーサである。In FIG. 3, 10 is an electrode substrate, X and Y are display electrode pairs, W is a selection electrode, 40 is a dielectric layer with a protective layer on its surface, 50 is a separator adjacent to the selection electrode W, and 60 is a cover substrate. , 80 is a fluorescent material, and 90 is a spacer.

およびセパレータ５０も薄膜法テ形成シ、保護層を蒸着
して電極基板１０が完成する。A pair of display electrodes X and Y is formed on the electrode substrate 10 by a thin film method, covered with a low melting point glass which becomes the dielectric layer 40, and a selection electrode W is formed on the electrode substrate 10 by a thin film method.
The separator 50 is also formed using the thin film method, and a protective layer is deposited to complete the electrode substrate 10.

にしたスペーサ９０を介して対向させ、該パネル周辺を
封止した後放電ガスを充填するのである。The cover substrate 60 is made thicker than in the case of a panel that does not use a phosphor, and is made of a substrate that is resistant to bending, and a phosphor of a desired color is printed in accordance with the electrode pinch. The side substrates are opposed to each other with a spacer 90 having a horizontal glass fiber having a constant diameter interposed therebetween, and after the periphery of the panel is sealed, a discharge gas is filled.

スペーサ９０を挿入して間隙距離を支えており、また厚
いカバー基板６０を使用して間隙の変化を防いでいた。Since the pressure of the discharge gas sealed between the electrode substrate 10 and the cover substrate 60 is generally less than one atmosphere, the atmospheric pressure acts to reduce the gap. When the gap is reduced, the distance between the display electrode and the phosphor that causes discharge is reduced.
The collision rate of ultraviolet rays that excites the phosphor on the cover substrate increases, resulting in a higher degree of collision, but on the other hand, the number of ion collisions also increases, shortening the lifespan. In order to prevent this, a spacer 90 independent from the cell is inserted to support the gap distance, and a thick cover substrate 60 is used to prevent the gap from changing.

外線によっても光るため、表示色純度が悪くなり表示画
面のコントラストを悪くしていた。In addition, since the phosphor films 80 of multiple colors on the cover substrate were simply painted separately and had no partition walls, the boundaries between them were unclear, and even worse, they were illuminated by stimulating ultraviolet rays from other display cells. As a result, the purity of displayed colors deteriorated and the contrast of the display screen deteriorated.
従来のパネルでは、異なった色を発色する螢光体を付着

でも誘起される。このことから、色にじみ、低コントラ
スト化などをまねいてい１こ。In the conventional panel, the coloring of the cover substrate 6 to which phosphors that emit different colors are attached is also induced by ultraviolet rays from sources other than the self-cells. This can lead to color bleeding and low contrast.

間にスペーサを挿入して一定に保とうとするが、該スペ
ーサが表示セルの放電領域を遮ることが多く、画素欠陥
を引き起こしていた。In surface discharge type gas discharge panels that do not provide fluorescent display, the distance between the cover substrate and the display substrate has little effect on the display. However, in a panel that displays color by coating a phosphor on a cover substrate, the gap from the display cell to the surface of the cover substrate directly affects the brightness. For this reason, spacers are inserted between the side substrates in an attempt to maintain a constant level, but the spacers often block the discharge area of the display cell, causing pixel defects.

サが各セルに付属する程多いので放電間隙の維持に有効
となる。By surrounding the outer area of the coated phosphor with a wall, it not only limits the ultraviolet rays that effectively stimulate the phosphor, but also allows the wall to function as a spacer, thereby blocking the display. Achieving a spacer with no spacer. Furthermore, since the more spacers are attached to each cell, the more spacers there are, the more effective it is to maintain the discharge gap.
セル毎の網目隔壁が励起紫外線を目的セルからのものに
限定すると共に、その網目隔壁がスペーサとなるために
、宙度の高いスペーサが、画素の表示を妨げることなし
に実現できる。The mesh partition walls of each cell limit the excitation ultraviolet rays to those from the target cell, and since the mesh partition walls serve as spacers, spacers with a high degree of space can be realized without interfering with pixel display.

基板製道順を示す図の順に説明する。An embodiment of the present invention will be described in the order of FIG. 2, a perspective view of a color display surface discharge type gas discharge panel of the present invention, and FIG. 1, a diagram showing a route for manufacturing a cover substrate of the present invention.

ある。In FIG. 2, 1 is an electrode substrate, X and Y are display electrode pairs,
W is a selection electrode, 4 is a dielectric layer, 5 is a separator, 6 is a cover substrate, 7 is a mesh, 8 is a phosphor, and 9 is a spacer.

構造を述べることにする。The electrode structure on the electrode substrate 1, the structure of the dielectric layer 4, the separator structure, etc. are the same as those in the conventional method, so they will not be described here. I will state this.
第１図において、まずカバー基板６上に第１図（ａｌで
示すようにメッシュ７を厚膜法で印刷を行い焼成する。In FIG. 1, first, as shown in FIG. 1 (al), a mesh 7 is printed on a cover substrate 6 by a thick film method and fired.

に印刷する。その状態を第１図ｆｂ）に示す。The height of the mesh is about 20 microns, but when the first phosphor mask is attached over the mesh and a paste made of the first phosphor fluidized with a solvent is printed, it will be inside the mesh. The first phosphor is buried. After drying and solidification, the second and third phosphor masks are similarly attached, and the second and third phosphors of different luminescent colors are printed in different meshes 7, respectively. The state is shown in FIG. 1 fb).

サとなるｙＸ膜材料を複数回印刷をして第１図（Ｃ）の
ように所望の高さにまで積み上げる。該個々の印刷工程
の間に前記したように乾燥固化が必要なのは言うまでも
ない。In this state, the yX film material serving as a spacer is printed several times on the mesh 7 forming the boundary of the display cells, and stacked up to a desired height as shown in FIG. 1(C). It goes without saying that drying and solidification as described above is necessary between the individual printing steps.
このようにしてできたスペーサの高さは厳密には均一で
はないが、ミクロンの程度のばらつきででき上がること
から、実際上は均−高スペーサとしての機能を充分果た
すことができる。Although the height of the spacer formed in this way is not strictly uniform, it can be formed with variations on the order of microns, so that in practice it can sufficiently function as a uniform-height spacer.
このスペーサ印刷のときメツシュの一辺の一方向だけに
印刷を行っても良く、またメ・７シユの全方向に行って
もよいが、メソシュの上からスペーサ印刷がずれないこ
とが必要である。In this spacer printing, printing may be performed in only one direction of one side of the mesh, or may be performed in all directions of the mesh, but it is necessary that the spacer printing does not shift from the top of the mesh.
上記印刷の後、該基板を焼成固化させるとカバー基板６
が完成する。After the above printing, when the substrate is fired and solidified, the cover substrate 6
is completed.
このようにしてできたカバー基板６と、すでに作っであ

目合わせを行うと、メッシュ７。When the cover substrate 6 thus made and the electrode substrate 1 already made are aligned with the printing side facing the electrode side and the cells are aligned, the mesh 7 is formed.

支柱ができ上がる。Spacer9. A column is created for each cell in which the spacer 9 and the separator 5 are in contact with each other, and the cell has a large area surrounded by the separator 5 or the like.
第１図ではメッシュ７の形状を矩形としているが、この
形は円、楕円、亀の中形など適宜選べるのは言うまでも
ない。In FIG. 1, the shape of the mesh 7 is rectangular, but it goes without saying that this shape can be selected as appropriate, such as a circle, an ellipse, or a turtle shape.
大発明の方法でカラー表示面放電形ガス放電パネルを作

小さく、従ってパネルが軽くでき上がる。以上述べたよ
うに本発明は当初の問題点（表示セルを遮らずに放電間
隙を一定に保つという問題点）を明快に解決している。By creating a color display surface discharge type gas discharge panel using the method of the great invention, spacers that do not interfere with the display can be densely provided for each pixel, and the discharge space can be maintained by distributing it over many cells. A fixed gap panel reduces the substrate thickness and therefore makes the panel lighter. As described above, the present invention clearly solves the original problem (the problem of keeping the discharge gap constant without blocking the display cells).
当該セル以外からの光励起が激減し、したかって色にじ
みの殆ど無い、コントラスト良好なガス放電によるカラ
一平面ディスプレイが得られることは耐相効果として好
ましい。It is preferable as a phase resistance effect that light excitation from sources other than the cell concerned is drastically reduced, and therefore a color one-plane display using gas discharge with good contrast and almost no color blurring can be obtained.
