本発明は液晶セルの製造工程、特に液晶を注入する際に
セルの注入孔周辺に付着した余分の液晶を回収する方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a process for manufacturing a liquid crystal cell, and more particularly to a method for recovering excess liquid crystal deposited around an injection hole of a cell during injection of liquid crystal.
液晶セルは通常、一対の電極板を所定の間隔に対向配置
し、周辺をシール剤によりシールし、シール部の１ケ所
又は２ケ所に設けられた注入孔より液晶を注入後、注入
孔を封止することによつて作成される。Usually, a liquid crystal cell has a pair of electrode plates arranged facing each other at a predetermined distance, the periphery is sealed with a sealant, liquid crystal is injected through an injection hole provided at one or two places in the sealing part, and then the injection hole is sealed. created by stopping.
液晶を注入する方法としては、セルと液晶を真空脱気可

ージさせることにより注入を行なう方法と、２つの注入
孔の一方に液晶を接触させ、他方より吸引することによ
つて注入する方法がある。The method for injecting liquid crystal is to place the cell and liquid crystal in a container that can be vacuum degassed, and after vacuum degassing, bring the liquid crystal into contact with the injection hole of the cell, and then fill the container with inert gas at normal pressure. There is a method of injecting by purging, and a method of injecting by bringing liquid crystal into contact with one of two injection holes and suctioning from the other.
いずれの注入方法においても注入の際の泡の混入を防ぐ
ため過剰の液晶に接触させる必要があり、注入孔周辺に
余分な液晶が付着してしまう。従来は、この注入孔周辺
に付着した余分の液晶をふきとつていたが、この余分に
付着した液晶の量は実際にセルに注入される量の１〜２
倍あり、極めて無駄が多い上に、安全衛生面、公害面に
おいても多くの欠点があつた。In either injection method, in order to prevent bubbles from entering during injection, it is necessary to contact excess liquid crystal, resulting in excess liquid crystal adhering to the vicinity of the injection hole. Conventionally, the excess liquid crystal that adhered around this injection hole was wiped off, but the amount of excess liquid crystal that adhered was 1 to 2 times the amount that was actually injected into the cell.
Not only was it twice as expensive, it was extremely wasteful, but it also had many drawbacks in terms of safety, health, and pollution.
本発明は、上記問題点に鑑みなされたもので、液晶を注
入する際にセル注入孔周辺に付着した余分の液晶を回収
する方法を提供するものである。The present invention has been made in view of the above problems, and provides a method for recovering excess liquid crystal that adheres around the cell injection hole when liquid crystal is injected.
即ち、本発明は液晶セルに液晶を注入する際に、セルの
注入孔周辺に付着した余分の液晶を保持体に接触させ、
該保持体に吸収された液晶を有機溶剤を用いて抽出し、
次いで溶剤と液晶を分離することを特徴とする。本発明
にあつては、液晶を注入した際に注入孔周辺に付着した
余分の液晶に対し保持体を接触させると毛細管現象によ
り、液晶が保持体に吸収される。That is, in the present invention, when injecting liquid crystal into a liquid crystal cell, excess liquid crystal attached around the injection hole of the cell is brought into contact with a holder,
Extracting the liquid crystal absorbed by the holder using an organic solvent,
The method is characterized in that the solvent and liquid crystal are then separated. In the present invention, when the holder is brought into contact with excess liquid crystal that has adhered around the injection hole when liquid crystal is injected, the liquid crystal is absorbed into the holder due to capillary action.

。実施例
第１図に示す様にセル１の注入孔２を液晶３に接触させ
て真空注入した。The liquid crystal absorbed by the carrier is extracted using a highly soluble organic solvent such as benzene, methanol, acetone, ethanol, toluene, and chlorofluorocarbon. The extracted liquid crystal is separated and recovered by vacuum degassing of the organic solvent, and is reused. In the present invention, the holder may be anything that has a capillary effect, such as quartz fiber,
Examples include fibers such as glass fibers, carbon fibers, metal fibers, asbestos fibers, slag fibers, and organic fibers, or yarns processed from these fibers, tape mats, cloths, sponges, etc., but in particular, any material that does not contaminate liquid crystals may be used. The shape is obtained,
A quartz fiber yarn with good capillary effect is preferred. EXAMPLE As shown in FIG. 1, the injection hole 2 of the cell 1 was brought into contact with the liquid crystal 3, and vacuum injection was carried out.

量は過剰液晶の約７０％であつた。At this time, the excess liquid crystal 4 attached to the periphery of the injection hole 2 of the cell 1 is absorbed by the yarn 5 of the quartz fiber (Fig. 2), and the excess liquid crystal around the injection hole 2 is removed (Fig. 3). Injection hole 2
was sealed with sealant 6 to obtain a liquid crystal cell. In this manufacturing process, the amount of liquid crystal absorbed into the quartz fiber yarns 5 was approximately 70% of the excess liquid crystal.

体に吸収させることにより、液晶の回収が可能となり、
液晶の無駄が著るしく低減された。The liquid crystals absorbed into the quartz fiber yarn were extracted using benzene, and then the benzene and liquid crystals were separated by degassing the benzene using a vacuum rotary evaporator, and approximately 60% of the excess liquid crystals were recovered. . As explained above, according to the present invention, excess liquid crystal attached around the injection hole of the cell can be recovered by absorbing it into the holder instead of wiping it off in the conventional method. ,
Liquid crystal waste has been significantly reduced.
又、繊維状の保持体を用いれば基板間の凹部に付着した
液晶も完全に吸い取りができる等の効果がある。Furthermore, if a fibrous holder is used, liquid crystal deposited in the recesses between the substrates can be completely absorbed.
