小さいために第5図に示すようにパネル内に気泡8が発
生してしまう。Problems to be Solved by the Invention In liquid crystal panels with this structure, the liquid crystal material shrinks in volume when placed in a low temperature environment (-20°C or lower), but if the spacer is made of a rigid material such as glass fiber, In some cases, the volume shrinkage rate of the spacer is one order of magnitude smaller than that of the liquid crystal material, so that bubbles 8 are generated within the panel as shown in FIG.

た場合は以下に述べる問題点があった。On the other hand, a spacer made of resin material has elasticity, so the sixth
As shown in the figure, as the liquid crystal material contracts, the gap between the substrates becomes smaller and no bubbles are generated. However, when a resin spacer was used, there were problems described below.
tJ7図に示すように液晶層の部分では入射光の偏光軸
が回転されているが、スベーサ一部では回転されない。As shown in Figure tJ7, the polarization axis of the incident light is rotated in the liquid crystal layer, but not in a part of the substrate.

いた。Here, 9a and 9b are polarizing plates. Therefore, for example, when the polarizing plates are arranged in parallel, the liquid crystal layer appears black when no voltage is applied, but a portion of the surface area appears white with light passing through. When using resin spacers, the number of spacers must be at least 200 pieces/Wl in order to keep the substrate gap constant and accurate.
2 or more was required, and the omission of part of the subesa was very noticeable.

硬化するものである。Means for Solving the Problems The present invention achieves the above objects by sandwiching a liquid crystal material between two substrates having transparent electrodes, and using a spacer material having rigidity and a spacer material having elasticity between the two substrates. and are selectively arranged. In addition, the manufacturing method involves forming a sealing material on the periphery of at least one of the substrates that has been subjected to an alignment treatment and has a pair of transparent electrodes, and forming a sealing material on the peripheral edge of at least one of the substrates, and forming a liquid crystal and an elastic material mixed with a rigid spacer material on the other substrate. After selectively dropping liquid crystal mixed with a spacer material having
The two substrates are bonded together in a vacuum, and then the sealing material is cured.
作用
このような構戊のパネルとすることにより、剛性を有す
るスペーサーを使用しているためスペーサーの個数が少
なくて済み光の抜けが目立たない。また低温下では弾性
・スペーサーを配置した部分でガラス間隔が小さくなり
液晶の体積収縮分を吸収することができるので気泡の発
生を防ぐことができる。Function: By using a panel having such a structure, since rigid spacers are used, the number of spacers is small, and light leakage is not noticeable. In addition, at low temperatures, the gap between the glasses becomes smaller in the area where the elastic spacer is placed, which absorbs the volume shrinkage of the liquid crystal, thereby preventing the formation of bubbles.

The liquid crystal 2b containing 0.05 wt% of the liquid crystal 2a is dropped at the middle position of the liquid crystal 2a that was dropped earlier. At this time, the total amount of liquid crystals 2a and 2b is set as the amount required for the liquid crystal panel. Next, the two glass substrates 1a and 1b are bonded together in a vacuum chamber, and then the sealing material 3 is irradiated with ultraviolet rays and cured.

Apply elastic baser 4 to the dripped area.
b is placed. In this liquid crystal panel, at a low temperature of -40 DEG C., as shown in FIG. 3, the distance between the substrates becomes smaller in the area where the elastic spacer 4b is arranged, so that the generation of bubbles can be prevented. Further, since the rigid spacer 4a is used, the number of spacers may be 5 to 50 per square 2, and light leakage in a part of the spacer is not noticeable.
