PURPOSE:To shorten a necessary charging time which is about 90min conventionally to about 4min by dripping liquid crystal on a glass plate, sticking the other glass plate, and discharging air. CONSTITUTION:A necessary amount plus 10-20% of liquid crystal 4 is dripped quantitatively on a lower soda glass plate 1a at a set position inside an adhesive 1c at atmospheric pressure from above. An upper soda glass plate 1b is inserted into a lower jig 2 and then orientation film patterns of both glass plates 1a and 1b are matched with each other automatically. They are put in a vacuum chamber 5, which is evacuated, so that the two soda glass plates 1a and 1b curve around the layer of the adhesive 1c as a fulcrum as shown in a figure. The gap at the center part of the soda glass plates 1a and 1b becomes large, so the liquid crystal 4 moves to the adhesive 1c by surface tension and the air 6 in the gap gathers in the center of the soda glass plates 1a and 1b. The pressure in the vacuum chamber 5 is returned to the atmospheric pressure. When a loaded roller 7 is rolled on the top surface of the soda glass plates 1a and 1b to apply pressure, the air 6 in the glass substrate 1 moves to one open side 1d and is discharged. |
