本発明は、液晶パネルの製造方法、とくにその電極部分
の組立て法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for manufacturing a liquid crystal panel, and particularly to a method for assembling electrode portions thereof.
（従来の技術） 第２図は従来の液晶パネルの構成を示す平面図である。(Conventional technology) FIG. 2 is a plan view showing the configuration of a conventional liquid crystal panel.

ない。In the figure, 1 is a first substrate, 2 is a second substrate, 3 is a common electrode, 4 is a conductive adhesive, and 5 is a sealing adhesive.
The state seen through the second substrate 2 is shown. That is, the electrode of the second substrate 2 is electrically connected to the common electrode 3 via the conductive adhesive 4. Moreover, the first substrate 1 and the second substrate 1
The substrates 2 are bonded together with a sealing adhesive 5. 1st
In addition to the common electrode 3, a large number of individual electrodes 6 are formed on the substrate 1. Of course, FIG. 2 shows a case where they are ideally bonded, and this is not the case in general.
（発明が解決しようとする問題点）
このような従来の液晶パネルの組立方法では、導電性接
着剤４が基板１及び２の貼り合せ時に拡がって隣接する
電極６と短絡する場合がある。特に、今後液晶パネルの
技術が進んで電極の配列ピッチが狭くなって来る場合を
考えると、ますます導電性接着剤４が共通電極３と隣の
電極６とを短絡させる危険性が多くなる。(Problems to be Solved by the Invention) In such a conventional method for assembling a liquid crystal panel, the conductive adhesive 4 may spread when the substrates 1 and 2 are bonded together, causing a short circuit with the adjacent electrode 6. In particular, if we consider that the electrode arrangement pitch will become narrower as liquid crystal panel technology advances in the future, there will be an increasing risk that the conductive adhesive 4 will cause a short circuit between the common electrode 3 and the adjacent electrode 6.
本発明はこのような問題点を解決するもので、電極配列
ピッチの微細化を容易に可能にすることを目的とするも
のである。The present invention is intended to solve these problems, and aims to facilitate miniaturization of the electrode arrangement pitch.

したがって共通電極と他の電極間の短絡が阻止される。(Means for Solving the Problems) In order to solve the above problems, the present invention provides a sealing adhesive 5
The common electrode 3 is isolated from the other electrodes 6 by changing the application pattern, thereby preventing the conductive adhesive 4 from flowing to the electrodes 6. The sealing adhesive applied in a thin layer to isolate the common electrode from the other electrodes prevents the conductive adhesive from spreading when bonding the first and second substrates together. death,
Short circuits between the common electrode and other electrodes are thus prevented.
（実施例）
第１図は本発明の一実施例を示す第２図と同様手法で描
いた透視平面図である。７は封止用接着剤５の拡開した
ふくらみ部であり、その他の１ないし６は第２図のもの
と同じものを指している。(Embodiment) FIG. 1 is a perspective plan view drawn using the same method as FIG. 2, showing an embodiment of the present invention. 7 is the enlarged bulge of the sealing adhesive 5, and the other numbers 1 to 6 are the same as those in FIG. 2.
ふくらみ部７は図のように、導電性接着剤４が塗布され
る位置を囲むようにして、電極６を導電性接着剤４の位
置から隔離するパターンになされている。As shown in the figure, the bulge 7 is formed in a pattern that surrounds the position where the conductive adhesive 4 is applied and isolates the electrode 6 from the position of the conductive adhesive 4.

まず、導電性接着剤４がそわら基板１及び２に圧着され

接着剤４の流動を阻止する。すなわち、導電性接着剤４
と導通している共通電極３も当然、封止用接着剤５によ

First, the conductive adhesive 4 is pressed onto the soft substrates 1 and 2 and begins to spread, followed by the sealing adhesive 5. At this time, since the sealing adhesive 5 is patterned to surround the conductive adhesive 4 as described above, it prevents the conductive adhesive 4 from spreading and flowing. That is, conductive adhesive 4
Naturally, the common electrode 3 which is electrically connected to the common electrode 3 is also prevented from coming into contact with the electrode 6 by the sealing adhesive 5.
なお、第１図では共通化ｔｉ ３の近傍めみ封止用接着

合がある。In addition, in FIG. 1, the pattern of the adhesive 5 for sealing in the vicinity of the common electrode 3 is expanded, but it is obvious that it may be expanded as a whole. It is necessary to prevent the sealing adhesive 5 from spreading to picture element parts (not shown), and therefore it may be better to have a narrower pattern width.

In the manufacture of liquid crystal panels that make electrical connections, it is possible to completely prevent short circuits between the common electrode and adjacent electrodes due to the spread of the conductive adhesive, making it easier to manufacture liquid crystal panels and improving yields. It has advantages that can be easily improved.
