本発明は大表示面、噴の液晶表示ノくネルに空気泡等を
混入することなく液晶を注入する方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for injecting liquid crystal into a liquid crystal display channel with a large display screen without introducing air bubbles or the like.
現在実用化さｎている液晶表示ノくネルは、２枚の基板

等を混入することなく液晶を注入することが可能であっ
た。In the liquid crystal display panel currently in practical use, liquid crystal is injected into the gap between two substrates. Because the substrate constituting the channel (in other words, display) is small, it was possible to inject liquid crystal without introducing air bubbles or the like due to capillary action just by filling the liquid crystal injection port with liquid crystal.
ところで、最近では大表示面積の液晶表示ノ（ネルの要
求が高まっている。ところが、表示面積が大きくなると
毛細管現象のみを利用した従来の注入方法では気泡の混

ことが容易でなくなるという欠点があった。By the way, recently there has been an increasing demand for liquid crystal displays with large display areas. However, as the display area becomes larger, it is impossible to avoid air bubbles from being mixed in using the conventional injection method that uses only capillary action. If the bubbles are large, the surface tension of the bubbles becomes larger than the force pushing up the liquid crystal due to the b-tubule phenomenon, and as a result, there is a drawback that it becomes difficult to remove the bubbles from the liquid crystal.
本発明は」二連した従来技術の欠点を解決するためにな
されたもので、大表示面積を持つ液晶表示パネルに気泡

の注入方法を実現することを目的とするものである。The present invention was made in order to solve the two drawbacks of the prior art, and provides a method for injecting a product that can inject seventh order crystal into a liquid crystal display panel with a large display area without introducing air bubbles. The purpose is to achieve this goal.
この目的を達成するため、本発明は液晶表示パネルを構

易に外にＩＳに排出するようにしたものである。In order to achieve this object, the present invention utilizes capillarity to fully inject liquid crystal into the gap between two substrates constituting a liquid crystal display panel, and at the same time applies ultrasonic vibration to the side substrates. This allows air bubbles mixed in the liquid crystal to be easily discharged to the outside from the air vent port.
以下図面を参照して本発明による成品の注入方法の一実
施例を説明すると、図におして１は？ｒｉ１面基板、２

向に延在している。An embodiment of the method for injecting a product according to the present invention will be described below with reference to the drawings. ri 1-sided board, 2
is a rear substrate, and linear transparent electrodes 3 and 4 are arranged on the opposing surfaces of side substrates 1 and 2, respectively, and these transparent electrodes 3 and 4 intersect at right angles to each other. ing. That is, each transparent electrode 4 arranged on the rear substrate 2 extends in a direction perpendicular to the drawing.
この前面基板１と後面基板２との間Ｖこは、図示しない

の外周部は接着等にょジｊｏ］止さ、ｌしている。A gap 5 between the front substrate 1 and the rear substrate 2 is set to 10 to 50 μm using a spacer (not shown).
9, an inlet 6 and an air vent 1'7 are provided on the opposite side of the outer periphery, and the remaining outer periphery is protected from adhesives, etc. , I'm doing it.
そこで、この間隙部５に液晶８全注入する場合、注入口

なると、間隙部５の途中に気泡９が生じることになり、
この気泡９が大きいと、その表面張力が毛細管現象によ

なり、気泡９（Ｉ′ｉ間隙部５内に残さ几たまま、液晶
８が気泡９の外部を通過して空気抜きロアに達すること
になる。Therefore, when the entire liquid crystal 8 is injected into the gap 5, when the injection port 6 is filled with the liquid crystal 8, the liquid crystal 8 enters the gap 5 due to the capillary phenomenon and advances in the direction of the air vent 1''7. I'm leaving. However, when the display area is wide, the front substrate 1 and the rear substrate 2 are large, and the distance from the injection port 6 to the air vent lower and the distance in the direction perpendicular to Figure 1i'i, i are long. A bubble 9 will be created in the middle of 5,
If this bubble 9 is large, its surface tension becomes larger than the force pushing up the entire liquid crystal 8 in the direction of the air vent 1 due to capillary phenomenon, and the liquid crystal 8 remains in the air bubble 9 (I'i gap 5). 9 and reaches the air vent lower.
そのため、本発明では超音波１動磯１０により前面基板
１及び後面基板２に超音波振動を与える。Therefore, in the present invention, ultrasonic vibrations are applied to the front substrate 1 and the rear substrate 2 by the ultrasonic single movable rock 10.
このように側基板１，２に超音波振動を与えると、気泡
９は液晶中で動き易くなり、浮力によって自から空気抜
き口γ全上昇するか、寸たは気泡９は微細化して液晶８
と共に空気抜き口１へ押上げられ、外部に排出さ几る。When ultrasonic vibrations are applied to the side substrates 1 and 2 in this way, the air bubbles 9 move more easily in the liquid crystal, and either the air vent γ completely rises by itself due to buoyancy, or the air bubbles 9 become fine and the liquid crystal 8
At the same time, the air is pushed up to the air vent 1 and discharged to the outside.
このようにして間隙部５から気泡９は敗除かｎる。In this way, the air bubbles 9 are eliminated from the gap 5.

部５から気泡９を容易に取除くことができる。。In the embodiment shown above, the bubbles 9 generated in the gap 5 are made to move easily in the liquid crystal 8 by applying ultrasonic waves to the two substrates 1.2. , ' or the air bubbles 9 are made microscopic by the ultrasonic pulse, so the air bubbles 9 can be easily removed from the gap 5. .
次に他の実施例について説明する。Next, other embodiments will be described.

効果をより高めることができる。In the above-mentioned embodiment, only the ultrasonic motion was applied to the front substrate 1 and the rear substrate 2 by the ultrasonic motor 10, but if the pressure of the air vent γ was further lowered by 8 steps, the air Since the air bubbles 9 become smaller, the air bubbles 9 generated in the gap 5 become smaller, and the effect of removing the air bubbles 90 by ultrasonic vibration can be further enhanced.

液晶８を回収するようにす才しば、前述の効果はル］待
できる。The injection speed of the liquid crystal 8 can be increased by lowering the pressure of the air vent lower and increasing the pressure of the liquid crystal 8 in the injection port 6. If the pressure of the liquid crystal 8 in the injection port 6 is increased only by increasing the pressure of the liquid crystal 8 at the air vent γ, the effect will be reduced. That is, in this case, the 71 da crystal 8 tries to completely flow through the gap 5 where it can easily pass through, so the number of bubbles 90 increases, and in order to extract the bubbles 9 from the air vent lower, the liquid crystal 8 also has to move considerably. This is because it must be emitted or destroyed. However, if the discharged liquid crystal 8 is collected, the above-mentioned effect can be obtained.
また、空気抜きロアの圧力全下げるとき、しばらくの時
間注入口６の圧力も下げるようにすると、気泡９の発生
が非常に少なくなるという利点がある。Furthermore, when the pressure of the air vent lower is completely lowered, the pressure of the injection port 6 is also lowered for a while, which has the advantage that the generation of air bubbles 9 is greatly reduced.
