Shown in the figure. In FIG. 4, 21 is a glass plate, 22 is a transparent electrode, 23 is an adhesive, 24 is a glass plate constituting the second substrate, 25 is a transparent electrode, 26 is a space, and 27 is an injected liquid crystal. A method for manufacturing a liquid crystal panel will be explained with reference to FIG.

Forming resin films before and after injection (Step A). Next, alignment treatment is performed by rubbing the resin film with a special cloth. Next, the step shown in C is a step of dispersing columnar glass fibers on one of the glass plates in order to accurately determine the distance between the two glass plates constituting the liquid crystal panel. D is a process of printing a resin adhesive for sealing on one glass plate, and usually printing is done on the glass plate on which spacers are not dispersed.

後に液晶２６を注入し、注入口を封止して完了する。23 is the printed adhesive pattern. In this state, the second
The glass plates 24 are stacked together. At this time, the glass plates 21 and 24 are bonded together using an adhesive 23. 26 is the space created at this time, where the anode will be injected later. Finally, liquid crystal 26 is injected and the injection port is sealed to complete the process.
発明が解決しようとする問題点 このような従来の構成では液晶注入工程が複雑になる。The problem that the invention seeks to solve Such a conventional configuration complicates the liquid crystal injection process.
即ち、第２図Ｅの貼合せ工程及び下の硬化を終了した後
、図示してないが注入口を通して空間２６を真空に引き
、充分空間２６が真空になったとき注入口を液晶溜に接
触させる。周辺の接着剤印刷が完全であれば液晶の注入
は容易であるが、もし小さい穴でもおいていると液晶の
注入はできない。That is, after completing the bonding process and curing of the lower part shown in FIG. let If the adhesive printing around the area is perfect, it is easy to inject liquid crystal, but if there are even small holes, liquid crystal cannot be injected.
また、従来の方式では注入前に真空引きの必要があり大
がかりな装置と時間が必要である。Furthermore, the conventional method requires evacuation before injection, requiring large-scale equipment and time.
本発明はこのような問題点を解決するもので、簡単な設
備で完全な封止を行なう方法を提供するものである。The present invention solves these problems and provides a method for performing complete sealing with simple equipment.
問題点を解決するだめの手段
この問題点を解決するために本発明は、注入口から液晶
を注入するのではなく、液晶を基板上に滴下した後二枚
のパネルを貼り合わせ封止しようとするものである。Means to Solve the Problem In order to solve this problem, the present invention does not inject liquid crystal from an injection port, but instead attempts to drip liquid crystal onto a substrate and then bond and seal the two panels. It is something to do.
作 用
この構成によシ、液晶は基板の中心部から外方へ広がり
、その時に気泡等も除去されることになる。また、注入
でなく、余分の液晶を外に押し出すので、注入できない
と言う不良はなくなる。Effect: With this configuration, the liquid crystal spreads outward from the center of the substrate, and air bubbles and the like are also removed at this time. Also, since the excess liquid crystal is pushed out instead of being injected, there will be no defects such as inability to inject.

After forming a resin film with a thickness of about 100 ml, its surface is rubbed with a cloth (steps A and B). Next, glass fibers of about 10 microns are dispersed on one substrate (Step C). An adhesive portion 3 is formed on a glass substrate 1 facing the substrate. This adhesive part 3
It is preferable to use a thermosetting resin adhesive that has been screen printed and then cured to the B stage, or a thermoplastic resin adhesive. Next, as shown at E, liquid crystal 4 is dropped onto glass substrate 1. The opposing glass substrate 5 is placed on top of the glass substrate 1 and pressed. The pressure may be applied from above, but it is also possible to place two glass substrates stacked together in a soft plastic bag, evacuate the entire bag, and seal the opening using high-frequency heat. When the gap between the substrates becomes sufficiently narrow and uniform, the sealing portion may be heated to complete sealing.

も良い。In addition, after dropping the liquid crystal, air vents are made at the four corners of the adhesive part 3 so that when the second glass substrate 6 is stacked on top of each other as shown in the bottom of Figure 2, the excess amount of air and liquid crystal can easily come out. After the adhesive portion 3 is sealed, the four corners may be sealed with a sealing resin.
