Description
【発明の詳細な説明】 本発明は液晶表示素子の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a liquid crystal display element.
従来、液晶表示素子を製造する場合の問題点と
して、セル内部の不純物による悪影響、残存気
泡、特に動的散乱型表示素子の場合の導電性成分
の不均一な分布が挙げられる。 Conventionally, problems in manufacturing liquid crystal display devices include the adverse effects of impurities inside the cell, residual air bubbles, and non-uniform distribution of conductive components, especially in the case of dynamic scattering type display devices.
一方、液晶材料をセル内へ充填する方法とし
て、真空注入法が多く用いられているが、この方
法は、セル内をある程度真空にした後、該セルを
液晶材料へ含浸させ、次に真空を破り液晶材料へ
大気圧を加えることによつてセル内部へ液晶を注
入する方法である。 On the other hand, the vacuum injection method is often used as a method for filling liquid crystal materials into cells, but this method involves creating a certain degree of vacuum inside the cell, impregnating the cell with liquid crystal material, and then removing the vacuum. This method injects liquid crystal into the cell by applying atmospheric pressure to the broken liquid crystal material.

た真空注入法ではセルの注入孔に近い部分の方が
導電性成分のセル表面への吸着量が大であつて、
該部分で電流密度が大になり、セル内での電流密
度を異ならせていた。 However, in the conventional vacuum injection method described above, impurities that have a negative effect on the liquid crystal, such as moisture and dirt remaining in the cell before injection of the liquid crystal, are pushed toward the inner wall of the seal on the opposite side of the injection hole in the cell when the liquid crystal is injected. (Some of it mixed with the liquid crystal at the time of injection, and then mixed into the liquid crystal as the atmospheric environment changed.) These contaminants have been a factor in the deterioration of liquid crystals. Further, as the inside of the cell returns from a vacuum state to atmospheric pressure, air bubbles remain, and the air bubbles become mixed into the liquid crystal, causing deterioration of the liquid crystal. Furthermore, in a dynamic scattering type liquid crystal display cell, since current flows inside the cell during display operation, it is ideal that the current density at each location within the cell be approximately equal. However, in the vacuum injection method described above, the amount of conductive components adsorbed to the cell surface is greater in the part of the cell closer to the injection hole;
The current density was high in this part, making the current density different within the cell.
本発明は上記従来欠点に鑑みなされたものであ
つて、セル内の液晶材料の不純成分の除去、或い
は液晶材料自体の分布の適正化を行なうことを目
的とする。 The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to remove impurity components of a liquid crystal material within a cell or to optimize the distribution of the liquid crystal material itself.
以下、本発明に係わる液晶表示素子の製造方法
の一実施例を図面を用いて詳細に説明する。 Hereinafter, one embodiment of the method for manufacturing a liquid crystal display element according to the present invention will be described in detail with reference to the drawings.

そして排出孔５は樹脂で封止する。 FIG. 1 shows a plan view of a cell for explaining an embodiment of the method for manufacturing a liquid crystal display element according to the present invention. In the figure, 1 is a glass substrate, 2 is a sealing member, 3 is a liquid crystal filling part, 4 is an injection hole, 5 is a discharge hole, and 6 is a discharge liquid crystal pool. In the figure, liquid crystal is injected into the cell using a vacuum injection method, and the liquid crystal flows in the direction of the arrow in the figure. Therefore, impurities or bubbles inside the cell are pushed out from the discharge hole 5 to the liquid crystal pool outside the cell and concentrated. After filling the liquid crystal, the injection hole 4 is sealed with resin. Further, the cell is divided along the X-X' line, and the portion of the discharged liquid crystal pool 6 is discarded.
The discharge hole 5 is then sealed with resin.
基板厚が比較的厚い場合は、第２図ａ，ｂに示

け、排出する液晶の量を多く取つてもよい。 When the substrate thickness is relatively thick, a dug portion 7 may be provided in the discharged liquid crystal pool 6 to increase the amount of liquid crystal discharged, as shown in FIGS. 2a and 2b.
以上説明した如く本発明によればセル内部に存
在する不純物或いは気泡を液晶注入時に除去で
き、又、動的散乱型の場合での導電性成分の分布
についても均一化できるものである。 As explained above, according to the present invention, impurities or air bubbles existing inside the cell can be removed when liquid crystal is injected, and the distribution of conductive components can also be made uniform in the case of a dynamic scattering type.
