部である。[Prior Art] Conventionally, a surface discharge type gas discharge panel is known as a kind of display panel using gas discharge, and the present inventors have already disclosed in Japanese Patent Application Laid-Open Nos. −7
8751, and Japanese Patent Application Laid-Open No. 62-22352 (Japanese Patent Application No. 60-166092). The surface discharge type display panel has a structure as shown in a perspective view in FIG. 2, for example. That is, 1 is a substrate, 2 is a cover substrate, X and Y are display electrodes, x and y on the electrodes are display discharge parts, A is a selection electrode, 3 is a dielectric layer, 4 is a separator, and 6 and 7 are partition layers. , 8 are phosphor parts.

ている。In FIG. 2, a pair of display electrodes X and Y having display electrode portions x and y arranged in parallel and partially projecting on a substrate 1, and a separator made of an insulating material after covering the electrodes with a dielectric layer 3 4 is provided with a selection electrode A disposed in a direction crossing the display electrode portions x and y insulated from each other, and one display electrode Y and the selection electrode A constitute a selection cell near the intersection thereof. A substrate 1 in which a set of the three electrodes described above is arranged in a matrix as discharge elements, and a portion surrounded by partitions 6 and 7 at a position corresponding to the matrix arrangement of the discharge elements. The discharge gas is sealed by hermetically sealing together with the other cover substrate 2 having the phosphor portion 8 inside.

部８は発光し、表示機能を果たす。An alternating sustaining voltage is applied between the display electrodes X and Y of the color surface discharge type gas panel, and a pulse that causes a discharge is applied between the selection electrode A and one of the display electrodes y to trigger the discharge. When applied, a continuous discharge F is caused between the display discharge portions x and y. Ultraviolet rays R are emitted from the discharge F to stimulate the phosphor and emit visible light suitable for display, so that the phosphor portion 8 attached to the inside of the cover substrate 2 emits light, and the display function is improved. Fulfill.
このようなカラー面放電形ガスパネルにおいて、従来
のカバー基板２上の隔壁は、第３図および第４図に示す
ように単一の透明材料６や不透明材料７を使って製作し
ていた。In such a color surface discharge type gas panel, the conventional partition on the cover substrate 2 is manufactured using a single transparent material 6 or a single opaque material 7 as shown in FIGS.
ところで、明るく明確な発光を得るために、発光点と
なる螢光体部を与えられた場所一杯にできるだけ大きく
できるように不透明な螢光体隔壁を厚膜印刷法で形成し
ようとする場合、印刷パターンとしては基板上に隔壁材
料が尖鋭に立ち上がるように作れたとしても、焼成工程
で厚膜材料が溶解して裾野を引いたように変形するため
尖鋭化は無理となり、どうしても基板との接線が不明確
な境界線になる。By the way, when it is intended to form an opaque phosphor partition wall by a thick film printing method so that a phosphor portion serving as a light emitting point can be made as large as possible in a given place in order to obtain a bright and clear light emission. As a pattern, even if the partition wall material is made to rise sharply on the substrate, sharpening becomes impossible because the thick film material dissolves and deforms as if drawing a foot in the firing process, and the tangent to the substrate is inevitably lost. It has unclear boundaries.
他方、この隔壁を薄膜法で実行しようとするとパター
ン精度は上がるものの隔壁材料の堆積に時間がかかり、
工数的に高価となる。On the other hand, if this partition is to be performed by the thin film method, the pattern accuracy is increased, but it takes time to deposit the partition material,
It is expensive in terms of man-hours.
また、パターンの変形を容認するとして、隔壁材料に
第３図のように透明な材料６を使うと、隔壁材料が崩れ
ても発光を大きく妨げることにはならないから、確かに
明るくはなるが、隣接する他セルからの発光が漏れて混
じり、当然色純度を悪くしてしまう。In addition, assuming that the deformation of the pattern is tolerated, if a transparent material 6 is used as the partition wall material as shown in FIG. 3, even if the partition wall material collapses, light emission will not be largely hindered, but it will surely become brighter. Light emission from other adjacent cells leaks and mixes, which naturally lowers color purity.
他セルからの混色を避け、コントラストを向上させる
ため、第４図のごとく不透明の隔壁材料７を隔壁全体に
使うと、確かにコントラストの良い、鮮明な表示が得ら
れるが、隔壁両端部裾野の広がりのため、発光している
螢光体周囲部分からの光を隠してしまう。このため輝度
が小さくなるのが大きな欠点である。If an opaque partition material 7 is used for the entire partition as shown in FIG. 4 in order to avoid color mixing from other cells and improve the contrast, a clear display with good contrast can be obtained, but the skirt of both ends of the partition can be obtained. Because of the spread, the light from the surrounding area of the phosphor that is emitting light is hidden. A major drawback is that the luminance is reduced.
上記のような問題点を解決するため、本発明において
はカバー基板２に接する部分の隔壁材料には、透明材料
を使い、焼成時に生じる隔壁裾野の広がり部分で発光が
隠蔽されないようにし、該透明隔壁の上には不透明な隔
壁材料を使用して他セルからの光の迷い込みを極力避け
るようにした２層隔壁構造を採用するとともに、該２層
隔壁層の各壁面を覆う態様で蛍光体をカバー基板上に形
成した構造特徴としている。In order to solve the above-mentioned problems, in the present invention, a transparent material is used as a partition wall material in a portion in contact with the cover substrate 2 so that light emission is not concealed in a widening portion of a partition skirt generated at the time of firing. On the partition walls, an opaque partition material is used to adopt a two-layer partition structure in which light from other cells is prevented from entering as much as possible, and the fluorescent material covers each wall surface of the two-layer partition layer. Is formed on the cover substrate.
上記のようにすると、透明なカバー基板２に接し、該
基板２と溶け合う部分を有する第１の隔壁層が透明であ

に妨害されることなく観察者の方向に通り抜ける。すな

ットを狭めることはほとんどないので輝度の向上を図る
ことができる。In this case, since the first partition layer that is in contact with the transparent cover substrate 2 and has a portion that melts with the substrate 2 is transparent, the luminescence of the phosphor attached to the inner surface of the partition is obstructed by the opaque substance. Pass in the direction of the observer without. That is, the display cell opening to the observer side is sufficiently large, and the display dots are hardly narrowed, so that the luminance can be improved.
一方、上記より大きい立体角すなわち表示面に平行に
近い紫外線は、紫外線に不透明な第１および第２の隔壁
6,7や同じく不透明な材料で作られているセパレータ４
に遮られて、他のセルを光らせることはほとんどない。On the other hand, the larger solid angle, that is, the ultraviolet rays which are close to being parallel to the display surface, are opaque to the first and second partitions.
Separator 4, made of 6, 7 or similarly opaque material
It is almost impossible for other cells to glow because of the interruption.
このようにしてコントラストや色純度の良い表示が得
られる。In this way, a display with good contrast and color purity can be obtained.
本発明の実施例を第１図に示すカラー面放電形ガスパ
ネルの断面図を参照して説明する。An embodiment of the present invention will be described with reference to a sectional view of a color surface discharge type gas panel shown in FIG.

層、７は不透明隔壁層、８は螢光体部である。The applied panel structure is almost the same as that described in the conventional example, but in detail, 1 is a substrate, 2 is a cover substrate, X,
Y is a display electrode, x and y are display discharge parts, 3 is a dielectric layer, A is a selection electrode, 4 is a separator, F is a sustain discharge region on the sustain electrode, R is ultraviolet rays emitted from the sustain discharge, 6 is A transparent partition layer, 7 is an opaque partition layer, and 8 is a phosphor part.

ル観察者に１つの色情報を与える。The discharge portions x, y on the display electrodes X, Y to which the alternating maintaining voltage is always applied alternately interact with the address pulse applied to the selection electrode A to trigger the discharge, and the discharge portions x, y of the display electrode A sustain discharge is induced in y. Ultraviolet rays R having a shorter wavelength than visible light are emitted from the light emitting portion F of the sustain discharge. The ultraviolet light R collides with the phosphor portion 8 and is converted into visible light having a wavelength determined by the phosphor, giving one color information to the viewer of the display panel.

から見てこの不透明隔壁７は紫外線光源の近くでその光

角は大きいものである。この不透明隔壁７の働きでパネ
ル内を迷走して色純度を悪くし、色度を狂わす迷紫外線
の悪効果は大いに軽減される。Here, the place where the discharge is active, that is, the ultraviolet ray generation region P
As seen from above, the opaque partition 7 has a large solid angle because the opaque partition 7 surrounds the light source near the ultraviolet light source. The opaque partition 7 strays in the panel to deteriorate the color purity and greatly reduces the adverse effect of stray ultraviolet rays which degrade the chromaticity.
本発明者らの経験によると、隔壁層の総高さを20〜10
0ミクロンとし、その高さの50％以下を透明層とするの
が実用的に効果が大きい。According to the experience of the present inventors, the total height of the partition layer was 20 to 10
It is practically effective to set the transparent layer to 0 micron and 50% or less of its height to be a transparent layer.
なお、面放電パネルの電極構成としては以上のような
３電極１絵素構成以外に単純な直交電極配置のものでも
良く、また本発明はAC放電形式のパネルに限らずDC放電
形の面放電パネルにも適用可能である。The electrode configuration of the surface discharge panel may be a simple orthogonal electrode arrangement other than the three-electrode one-pixel configuration as described above, and the present invention is not limited to the AC discharge type panel but may be the DC discharge type surface discharge. It is also applicable to panels.
本発明により従来の面放電ガス放電パネルの色純度が
良くなかった透明隔壁層を有するパネルと、色純度は良
いが、開口率が小さくしたがって表示が暗くなっていた
不透明隔壁層をもつパネルと比較して、色純度，開口率
共に良好なパネルが得られた。Compared with a panel having a transparent partition wall layer having poor color purity of a conventional surface discharge gas discharge panel according to the present invention, and a panel having an opaque partition layer having good color purity but a small aperture ratio and therefore dark display. As a result, a panel having good color purity and good aperture ratio was obtained.
本発明の方法は地味であるが、着実に効果のある成果
を与えている。The method of the present invention is modest, but has steadily yielded effective results.
