本発明は、分散型ＥＬ（エレクトロ・ルミ、ネッセント

徴とする分散型ＥＬ発光素子に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dispersion type EL (electroluminescent, nescent) light emitting device, and more specifically, to improvement of adhesion between laminated layers and between a binder layer and an electrode surface, and bonding of two or more types. The present invention relates to a dispersion type EL light-emitting element characterized by imparting high brightness retention by combining agents.
従来、分散型ＥＬは、比較的誘電率の高い有機結合剤、
例エバ、シアノエチル化セルロースやシアノエチル化ポ
リビニルアルコールなどに、螢光体およびチタン酸バリ
ウムや二酸化チタンなどの高誘電体を各々分散させた薄
膜を積層させたものが基本的な構成形態の１つになって
いる。Conventionally, dispersed EL uses an organic binder with a relatively high dielectric constant,
For example, one of the basic configurations is one in which a thin film in which a phosphor and a high dielectric material such as barium titanate or titanium dioxide are dispersed is laminated onto cyanoethylated cellulose or cyanoethylated polyvinyl alcohol. It has become.

することである。発光効率低下の最大の要因は、螢光体
周辺および外部雰囲、気から浸入する湿気の影響が支配
的と云われており、実験上からも、そのような傾向がみ
られろ。A major performance problem and technical issue with these EL luminescent materials is that the luminous efficiency of the phosphor, which is composed of the base zinc sulfide and the activator, decreases over time. be. It is said that the biggest factor in the decrease in luminous efficiency is the influence of moisture infiltrating from the surroundings of the phosphor, the external atmosphere, and the air, and this tendency can also be seen from experiments.
そして、そのメカニズムについては明確でなく、まだ推
測の域を出ていないのが現状である。At present, the mechanism is not clear and is still in the realm of speculation.
一方、ＥＬ発光寿命の改良については、種々の方策が提
案されているが決定的なものがでていないのも現状であ
る。On the other hand, various measures have been proposed to improve the EL emission life, but at present no definitive measures have been taken.
一般的に、多糖類やポリオールをベースとしてそれをシ
アノエチル化することにより得られ一文、水分子の混入
移行しやすいものであるため、分散螢光体粒子への防湿
と云う面では、好ましいもの゛でない。In general, it is obtained by cyanoethylating a polysaccharide or polyol as a base, and since it is easy for water molecules to be mixed and transferred, it is preferable in terms of moisture proofing to dispersed phosphor particles. Not.
他の結合剤で比較的、疎水性で、吸湿性も小さく誘電率
のや＼高いものとしてフッ素樹脂が挙げられる。Another example of a binder that is relatively hydrophobic, has low hygroscopicity, and has a rather high dielectric constant is fluororesin.
螢光体および無機高誘電体微粉末をフッ素樹脂に分散し
て前記の如き発光素子を作製した場合、発光寿命（初期
輝度の半減期）の面では、前述多糖類ベースの結合剤を
使用した場合に比べて長寿命化する。When a light-emitting device like the one described above is prepared by dispersing a phosphor and an inorganic high dielectric fine powder in a fluororesin, in terms of luminescence life (half-life of initial brightness), it is difficult to use the polysaccharide-based binder described above. The lifespan will be longer than in the case of
しかし反面、発光輝度が低いレベルのものしか得られな
い。However, on the other hand, only a low level of luminance can be obtained.
これは、フッ素樹脂の誘電率の面からみて限と 界偵考えられる。This is a limit in terms of the dielectric constant of fluororesin. I can think of Kai.
さらに今ひとつの問題点として、フッ素樹脂のみによる
発光素子においては、薄膜間の接着性および薄膜と電極
表面との接着性が不十分なことが挙げられる。Another problem is that in light emitting elements made only of fluororesin, the adhesion between thin films and the adhesion between thin films and electrode surfaces is insufficient.
これら欠点を他のものにより補ないながらすでに保持す
る特性を引き出すことにより全体的にバランスを持たせ
ると云う観点より鋭意検討を重ねた結果、本発明に到達
したものである。The present invention was arrived at as a result of intensive studies from the viewpoint of creating an overall balance by bringing out the characteristics that are already maintained while compensating for these drawbacks with other materials.
即ち、本発明は、相対向する電極間に、誘電率２５以上
（ｌ ＫＨ２）であるところの２つの高誘電性有機薄膜
層と、フッ素樹脂よりなる発光層との、三層を挟む構造
よりなり、該発光層の両面がそれぞれ１つの高誘電性有
機薄層と、無機誘電体微粉末を分散したもう１つの高誘
電性有機薄膜層とによって圧着積層されることを特徴と
する分散型ＥＬ発光素子に関するものである。That is, the present invention has a structure in which three layers are sandwiched between opposing electrodes: two highly dielectric organic thin film layers with a dielectric constant of 25 or more (l KH2) and a light emitting layer made of fluororesin. Dispersed EL, characterized in that both sides of the light emitting layer are laminated by pressure bonding with one highly dielectric organic thin layer and another highly dielectric organic thin film layer in which inorganic dielectric fine powder is dispersed. This invention relates to light emitting elements.
こ−で誘電率２５以上（Ｉ ＫＨｚ ）である高誘電性
有機薄層を構成する有機結合剤とは、多糖類のグリセロ
ール化物をシアノエチル化したもの、あるいは、多糖類
のシアノエチル化物、さらに他の高誘電性の有機化合物
であってもよい。The organic binder constituting the highly dielectric organic thin layer having a dielectric constant of 25 or more (I KHz) is a cyanoethylated glycerolated polysaccharide, a cyanoethylated polysaccharide, or a cyanoethylated polysaccharide. It may also be a highly dielectric organic compound.
常温で液状を１するものは、他の固型の有機成分と混合
して造膜性を付与されるがその場合、混合物系での誘電
率は上記値を満すことが必要である。A material that is liquid at room temperature can be mixed with other solid organic components to impart film-forming properties, but in that case, the dielectric constant of the mixture system must satisfy the above value.
具体例としては、例えば、グリ士ロール化プルランのシ
アノエチル化物、クリセロール化ヒドロキシエチルセル
ロースのシアノエチル化物、グリセロール化可溶性デン
プンのシアノエチル化１ｉｌＪ、グリセロール化シュク
ロースのシアンエチル化物、グリセロール化ポリビニル
アルコールのシアノエチル化物およびシアノエチル化シ
ュクロースなどが挙げられる。Specific examples include cyanoethylated products of glycerolated pullulan, cyanoethylated products of chrycerolated hydroxyethyl cellulose, cyanoethylated products of glycerolated soluble starch 1ilJ, cyanoethylated products of glycerolated sucrose, cyanoethylated products of glycerolated polyvinyl alcohol, and Examples include cyanoethylated sucrose.
これらの結合剤は単独かあるいは２種以上の混合系で用
いられるが、その誘電率はｌ ＫＨ２で２５以上あるこ
とが必要である。２５未満では、積層発光体の輝度は不
十分である。These binders may be used alone or in a mixed system of two or more, but it is necessary that their dielectric constant is 25 or more in lKH2. If it is less than 25, the luminance of the laminated light emitter is insufficient.
フッ素樹脂としては、一般的には溶剤に可溶性のものが
好ましいが、不溶性のものであっても、螢光体粉末と溶
融ブレンドおよびフィルム化できるものであれば適用さ
れる。As the fluororesin, it is generally preferable to use one that is soluble in a solvent, but even insoluble ones can be used as long as they can be melt-blended with the phosphor powder and formed into a film.
具体例としては、例えば、フッ化ビニリデン−六フッ化
プロピレン共重合体、ブ１ゲ化ヒニリデンー四フッ化エ

素子を得た。Meanwhile, at the same time, a thin layer of about 30μ of C-paste was similarly formed on a transparent electrode film, and a thin layer of titanium facial barium 8. By screen printing a paste consisting of Of, liquid D 7, and Og, and forming an insulating layer of fluororesin with a thickness of about 15μ in the same way, and thermocompression bonding the two, the binder is made of fluororesin only. A light emitting device composed of the following was obtained.
