Abstract

PURPOSE:To inject liquid crystal quickly and evenly even in a cell with a large area by injecting the liquid crystal under the condition that space between the cells is opened, discharging the liquid crystal until the cell space is reduced to a prescribed interval and then sealing the hole for injection and discharge. CONSTITUTION:Spacers 6 are arranged in the liquid crystal filling part between glass electrode plates. To open a cell, the cell is placed on a fixed board with a vacuum chuck for example and pulled up with the vacuum chuck from the other side of the cell. If liquid cell 5 is injected from holes 4 under the condition that the cell space is opened, the liquid crystal can be injected easily and quickly by a pressure injector because the cell space is opened wide enough. The external force windening the cell space is removed, the liquid crystal is discharged from dicharging holes to control the cell space with spacers 6 so as to leave a prescribed interval and then the holes are sealed. To discharged the liquid crystal, a method sucking liquid crystal from the holes by pressure reduction or a method discharging the liquid crystal from holes under the pressure from the outside of the cell can be selected.
