【発明の詳細な説明】
本発明は液晶表示装置に関し、長寿命で信頼性の高い液
晶表示セルの封止構造を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display device, and provides a sealing structure for a liquid crystal display cell that has a long life and is highly reliable.
従来、液晶注入口の封口方法としては、樹脂を用いる方
法、低融点金属を用いる方法等がある。Conventionally, methods for sealing a liquid crystal injection port include a method using resin, a method using a low melting point metal, and the like.
このうち低融点金属を用いる方法は、長寿命、高信頼性
等の利点により広く用いられている。Among these, methods using low melting point metals are widely used due to their advantages such as long life and high reliability.
具体的な方法は、第１図に示すように、対向配置された
基板ガラス１，１′、スペーサ２により囲まれた液晶３
の封入部のガラス２，２′の側端面にある液晶注入口６
の周辺に金属４を真空蒸着しておき、液晶３を注入後に
低融点金属５で封口するものである。The specific method is as shown in FIG.
Liquid crystal injection port 6 on the side end surface of the glass 2, 2' of the enclosure part
A metal 4 is vacuum-deposited around the periphery of the liquid crystal 3, and after the liquid crystal 3 is injected, the liquid crystal 3 is sealed with a low melting point metal 5.
この方法は、金属４とガラス基板１，１′との密着度と
金属４と低融点金属５との密着度が液晶の寿命に及ぼす
影響は犬であり、液晶セルの寿命を延ばすには、密着性
の良い金属及び低融点金属を使用することが必要である
。In this method, the degree of adhesion between the metal 4 and the glass substrates 1, 1' and the degree of adhesion between the metal 4 and the low melting point metal 5 have a limited effect on the life of the liquid crystal, and in order to extend the life of the liquid crystal cell, It is necessary to use a metal with good adhesion and a low melting point metal.
本発明は、上述の考えに基づいて成されたもので金属層
を４層設けることにより液晶を外気から完全にしゃ断し
、さらに長寿命、高信頼性の液晶セルを提供することを
目的とするものである。The present invention was made based on the above idea, and aims to provide a liquid crystal cell with a long life and high reliability by completely cutting off the liquid crystal from the outside air by providing four metal layers. It is something.
以下、図面とともに本発明を実施例に基づいて説明する
。Hereinafter, the present invention will be explained based on examples together with the drawings.
°第２図は、本発明による液晶セルの平面図及びそのＢ
−Ｂ’断面図であって第１暁と同一のものには同一番号
を付している。° Figure 2 is a plan view of a liquid crystal cell according to the present invention and its B
-B' sectional view, and the same numbers as those in the first dawn are given the same numbers.
ガラス基板１，１′をスペーサ兼用のシール材２を介し
て互いに平行にさらに注入口６側の側端面をずらして図
のように設置しである。Glass substrates 1 and 1' are placed parallel to each other with a sealing material 2 also serving as a spacer interposed therebetween, with the side end surfaces facing the injection port 6 being offset as shown in the figure.
１０はガラスと密着力の強い金属すなわちチタンを使用
してあり、矢印の方向から液晶注入口６０周辺部のガラ
ス１，１′の端部に真空蒸着で付着させる。10 is made of a metal that has strong adhesion to glass, namely titanium, and is applied by vacuum deposition to the ends of glasses 1 and 1' around the liquid crystal injection port 60 from the direction of the arrow.
１１はニッケルでこれはチタンと同様に真空蒸着する。11 is nickel, which is vacuum-deposited like titanium.
次に銀１２を同様に付着させる。Next, silver 12 is similarly deposited.
こうしたのち、さらにその上にインジウム１３を同様に
付着させる。After this, indium 13 is further deposited thereon in the same manner.
その後、ガラス基板１，１′、シール材２で囲まれた間
隙内に真空含浸等の方法で液晶３を充填して低融点金属
であるインジウム１３を溶かして液晶注入口６の全面を
インジウムよりなる封止金属２３で覆う。After that, the liquid crystal 3 is filled into the gap surrounded by the glass substrates 1 and 1' and the sealing material 2 by a method such as vacuum impregnation, and the indium 13, which is a low melting point metal, is melted to cover the entire surface of the liquid crystal injection port 6 with indium. It is covered with a sealing metal 23.
ニッケル１１及び銀１２は、チタン及びインジウム相互
間の密着力を増すためのものであり、ハンダ付げによる
引張り試験、及び実際に液晶を封入してからの５０℃、
９０％での液晶の劣化試験を行った結果、前述のように
ニッケルと銀を用いるのが最良の方法であるということ
がわかった。Nickel 11 and silver 12 are used to increase the adhesion between titanium and indium, and are tested in tensile tests by soldering and at 50°C after actually sealing the liquid crystal.
After conducting a 90% liquid crystal degradation test, it was found that the best method was to use nickel and silver as described above.
以上のように、本発明はガラスと密着力の強いチタンを
用Ｌ・、ニッケル、銀およびインジウムにより封止を行
うもので長寿命、高信頼性の液晶セルが得られる工業上
人なる効果を持つものである。As described above, the present invention uses titanium, which has strong adhesion to glass, and seals it with nickel, silver, and indium, and has the industrial effect of providing a long-life, highly reliable liquid crystal cell. It is something you have.
