する液晶である。 In the figure, 1 is a front transparent electrode substrate (first electrode substrate) in which I o2 O 3 , S o O 2 , etc. are adhered to a transparent substrate such as a glass plate, and 2 is this front transparent electrode substrate 1.
(a second front electrode 3 arranged on the surface of the front electrode substrate 1), a second front electrode 3 constituting an external lead-out connected to an external electric circuit; 4 is a back transparent electrode substrate that faces the front transparent electrode substrate 1; 5 is a back transparent electrode substrate that faces the first and second front electrodes 2 and 3 disposed on the surface of the back transparent electrode substrate 4 through a predetermined gap; back electrode, 6
7 is a sealing material provided around the front transparent electrode substrate 1 by a printing method, and 7 is a conductive material provided inside the sealing material 6, containing conductive particles such as gold, silver, copper, aluminum, and graphite. This is a conductive material that connects the second front electrode 3 and the back electrode 5 made of a material. The conductive material 7 is provided in a dotted manner on one of the second front electrode 3 and the back electrode 5, for example, at the terminal portion of the back electrode 5, and is connected to the front transparent electrode substrate 1 and the back transparent electrode substrate. When the second front electrode 3 and the back electrode 4 are bonded together, the second front electrode 3 and the back electrode are electrically connected.

判明した。 In the liquid crystal display element configured as described above, the front electrode 3 and the back electrode 5 are electrically connected by the conductive material 7. However,
If high reliability is required, for example -30℃
In a heat shock test in which the conductive material 7 was alternately left in an atmosphere of 80°C and 80°C, it was found that the conductive material 7 became incompletely conductive after several cycles. In order to eliminate this drawback, there is a method of increasing the size of the connection point at one connection point.
In this method, since the area to be crimped is large, the spacing between the elements becomes non-uniform, which affects the characteristics of the liquid crystal display element after crimping. Therefore, the diameter of one connection point is limited to about 1.5 mm, and it has been found that this diameter causes incomplete conduction and does not provide the required reliability.
この発明は、上記欠点を解消るためになされた
もので、１接続個所について、２点以上の接続点

る。 This invention was made in order to solve the above-mentioned drawbacks, and by providing two or more connection points for one connection point and pressing both substrates and crimping the conductive material to the electrode, adhesion and conduction can be achieved. It is an object of the present invention to provide a method for manufacturing a liquid crystal display element that can improve reliability, can be bonded with low pressure, has low distortion of substrates, and can make gaps between substrates uniform.
以下、この発明の一実施例を説明する。 An embodiment of this invention will be described below.
例えば、90mm×30mmの透明導電基板と90mm×25
mmの透明導電基板に夫々所定のパターニングを行
なつた後、夫々の内側を配向処理を行なう。次に
裏透明電極基板の周辺部分に有機接着材を所定の
形状に印刷する。裏透明電極基板には、表透明電

図に示すように一辺の長さ約2.mmの正三角形の頂
点３箇所に、直径約0.3mmの円形のパターンで黒
鉛を主成分とする導電材７ａ，７ｂ，７ｃを印刷
した後、表透明電極基板と裏透明電極基板を接着
する。このとき、上記の正三角形の各頂点の導電
材は表透明電極基板と裏透明電極基板とに圧着さ
れるため約0.9mm程度に直径が拡大されて表透明
電極基板に接続される。 For example, a 90mm x 30mm transparent conductive substrate and a 90mm x 25
After performing predetermined patterning on each of the transparent conductive substrates having a diameter of 2 mm, the inside of each substrate is subjected to alignment treatment. Next, an organic adhesive is printed in a predetermined shape around the back transparent electrode substrate. The back transparent electrode substrate has a third connection point for each connection point with the front transparent electrode substrate.
As shown in the figure, after printing conductive materials 7a, 7b, and 7c whose main component is graphite in a circular pattern with a diameter of about 0.3 mm at the three vertices of an equilateral triangle with a side length of about 2 mm, the front Adhere the transparent electrode substrate and the back transparent electrode substrate. At this time, the conductive material at each vertex of the above-mentioned equilateral triangle is pressed to the front transparent electrode substrate and the back transparent electrode substrate, so that the diameter is expanded to about 0.9 mm and connected to the front transparent electrode substrate.
なお、接続点は第１図のように周辺封止材中に
設けてもよいし、空気中又は、液晶中に露出させ
てもよい。また、導電材としては、本実施例で
は、黒鉛を主成分とする導電材を用いたが、この
他に金、銀、銅、アルミ、錫等の金属粒子を含む
ものでもよい。 Note that the connection points may be provided in the peripheral sealing material as shown in FIG. 1, or may be exposed in the air or in the liquid crystal. Further, as the conductive material, in this embodiment, a conductive material containing graphite as a main component was used, but it may also contain metal particles such as gold, silver, copper, aluminum, and tin.
このようにして作られた液晶表示素子は、例え
ば、−30℃と80℃の雰囲気中に交互に放置するヒ
ートシヨツク試験を数十回以上実施しても、接続
点の導通不良は発生しないという実験結果を得
た。 Liquid crystal display elements made in this way do not suffer from conduction failures at the connection points, even if they are subjected to heat shock tests in which they are left in an atmosphere of -30°C and 80°C several dozen times or more. We got the experimental results.
これは１つの接続個所を複数の接続点で構成し
たためである。また、複数の接続点とすることに
より、接触面積を同じにするためには、各接続点
の直径を従来より小さくでき、導電材がより小さ
い圧力で一様に圧着され、表透明電極基板と裏透
明電極基板とのギヤツプが均一となる。 This is because one connection point is composed of a plurality of connection points. In addition, by providing multiple connection points, the diameter of each connection point can be made smaller than before in order to make the contact area the same, and the conductive material can be crimped uniformly with less pressure, and the surface transparent electrode substrate and The gap with the back transparent electrode substrate becomes uniform.
さらに、圧着が小さい圧力でできることにより
基板の歪も小さくなる。これは、１つの接続個所
において、同程度の接触面積を得るために、３つ
の導電材を使用したとき、その１つの導電材の体
積をａとし、他方１つの導電材のみを使用したと
き、その導電材の体積をＡとすると、3a×２≒
Ａ程度になり、そのため両基板間を狭める方向へ
押圧する圧力は、３つの導電材を使用したとき
は、１つの導電材のみを使用したときの１／２以
下となることに基因している。 Furthermore, since crimping can be performed with low pressure, distortion of the substrate is also reduced. This means that in order to obtain the same contact area at one connection point, when three conductive materials are used, the volume of one conductive material is a, and when only one conductive material is used, If the volume of the conductive material is A, then 3a×2≒
This is due to the fact that when three conductive materials are used, the pressure to narrow the space between the two substrates is less than half of that when only one conductive material is used. .
以上のように、この発明によれば表電極と裏電
極との１つの接続個所に２点以上の導電材を配設
し、両基板を対向させて両基板を狭める方向に押
圧し上記導電材を上記電極に圧着させたので、小
さい圧力で圧着でき信頼性の高い液晶表示素子が
製造できる効果がある。 As described above, according to the present invention, two or more conductive materials are disposed at one connection point between a front electrode and a back electrode, and the conductive material is pressed in a direction that narrows both substrates while facing each other. Since it is crimped onto the electrode, it can be crimped with a small pressure and a highly reliable liquid crystal display element can be manufactured.
