本発明は、液晶セル用洗浄剤、詳しくはガラス基板を用
いた液晶セル用洗浄剤に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning agent for liquid crystal cells, and more particularly to a cleaning agent for liquid crystal cells using glass substrates.

液晶セルは、透明電極を有する２板の基板を微小間隔、
例えば１０μ層以下の間隔を保って配設し、この間に液
晶物を封入し、上下基板間の電極に電圧を印加して、液
晶の配向方向の変化。The moxa liquid crystal cell is made by connecting two substrates with transparent electrodes at a minute interval.
For example, the alignment direction of the liquid crystal can be changed by disposing the layers with a spacing of 10 μm or less, sealing a liquid crystal material between them, and applying a voltage to the electrodes between the upper and lower substrates.
相変換等利用して画像表示を行なうものである。Image display is performed using phase conversion or the like.
液晶セルの製造に際しては、透明電極が形成された２枚
の基゛板間に液晶を封入すべく、一部間口を残して上下
基板をその周縁部で接着剤により貼り合わせて液晶室を
形成し、空の液晶セルを作成する。この空セルは、真空
にした注入室内で開口部が液晶物質中に浸され、ついで
。When manufacturing a liquid crystal cell, in order to seal the liquid crystal between two substrates on which transparent electrodes are formed, a liquid crystal chamber is formed by bonding the upper and lower substrates together at their peripheries, leaving a partial gap. and create an empty liquid crystal cell. This empty cell is then immersed at the opening into the liquid crystal material in an evacuated injection chamber.
注入室を大気に開放することにより、液晶物質が基板間
に吸引され、開口部をシールすることにより、基板間に
液晶物質の封入された液晶セルが形成される。By opening the injection chamber to the atmosphere, the liquid crystal substance is drawn between the substrates, and by sealing the opening, a liquid crystal cell is formed in which the liquid crystal substance is sealed between the substrates.
しかしながら、液晶室外の基板上に引き出されている電
極端子間の間隔は１０〜５０μ−程度と狭く、よりいっ
そうの微細化が検討されている。However, the spacing between the electrode terminals drawn out on the substrate outside the liquid crystal chamber is as narrow as about 10 to 50 microns, and further miniaturization is being considered.
このような引比し電極間にゴミ等の異物が付着すると、
絶縁不良を起こし誤動作の原因となるため、液晶セルの
製造後に洗浄することが必要となる。さらに、２枚の液
晶セル基板の接着部の外側には、液晶セル基板が微小ギ
ャップで対向する空隙部の生じることが避けられない。If foreign matter such as dust adheres between these comparison electrodes,
Since this can cause insulation failure and malfunction, it is necessary to clean the liquid crystal cell after manufacturing it. Furthermore, it is unavoidable that a gap is formed outside the bonded portion of the two liquid crystal cell substrates, where the liquid crystal cell substrates face each other with a small gap.
そのため、空セルへの液晶の注入時に、毛細管現象によ
り液晶がこの空隙部に入り込む。この液晶をそのままに
しておくと、液晶が大気中の汚染物質を溶解して絶縁不
良を起こしやすいため、液晶を侯浄除去する必要がある
。しかし、この空隙部のギャップは５〜１０μｌ程度と
狭いため、入り込んだ液晶を洗浄除去することは困難で
あり、従来はフロン系溶剤や塩素系溶剤を用いて、洗浄
、除去していた。Therefore, when liquid crystal is injected into an empty cell, the liquid crystal enters the gap due to capillary action. If this liquid crystal is left as is, it is likely to dissolve pollutants in the atmosphere and cause insulation failure, so it is necessary to clean and remove the liquid crystal. However, since the gap of this cavity is narrow, about 5 to 10 μl, it is difficult to wash and remove the liquid crystal that has entered, and conventionally, fluorocarbon-based solvents or chlorine-based solvents have been used to wash and remove it.
しかしながら、これらの有機系溶剤は優れた洗浄性能を
有する反面、環境への安全性に太きな問題を有しており
、近年、水系の洗浄剤の要望が高まっている。However, although these organic solvents have excellent cleaning performance, they have serious problems with respect to environmental safety, and in recent years, the demand for water-based cleaning agents has increased.
