本発明は上記従来の欠点を解消せんとするものであって
、以下、本発明を第６図、第７図において説明する。However, according to the conventional method described above, the vacuum chamber (liquid crystal α6 according to the policy) must be refilled to 3 m (lυ) every time the - injection process is completed, and this work is troublesome. in,
Productivity is poor, and during that time, the liquid crystal (1G+ spills from the saucer 0υ, liquid crystal u6) is wasted.Furthermore, the liquid crystal αe is filled to the top of the saucer 0υ, and is evacuated in this state. Therefore, the air present in the liquid crystal (+61) is discharged, but with this discharge, the liquid crystal Qf19 flows down from the long groove α9, causing waste in the liquid crystal 06), which has the disadvantage of being uneconomical. The present invention aims to solve the above-mentioned conventional drawbacks, and the present invention will be explained below with reference to FIGS. 6 and 7.
