Abstract
An apparatus and method are provided for deaerating liquid crystal contained in at least one liquid crystal container. The apparatus includes a chamber, a holder, a displacement mechanism, a vacuum system and a gas supply. The chamber has an opening to provide access to an interior of the chamber and a cover to seal the opening. The holder is disposed in the chamber to hold the liquid crystal container having the liquid crystal while the displacement mechanism displaces the at least one container. Here, the vacuum system creates a vacuum state in the chamber during deaeration, and the gas supply restores the chamber to atmospheric pressure.

An apparatus for deaerating liquid crystal contained in at least one liquid crystal container, comprising:
- a chamber having an opening to provide access to an interior of the chamber and a cover to seal the opening;
- a holder disposed in the chamber to hold the at least one liquid crystal container having the liquid crystal;
- a displacement mechanism to displace the at least one container;
- a vacuum system to create a vacuum state in the chamber;
- and
- a gas supply to restore the chamber to atmospheric pressure.
A method for deaerating liquid crystal, comprising the steps of:
- filling the liquid crystal into at least one liquid crystal container;
- positioning the at least one liquid crystal container having the liquid crystal filled therein in a chamber;
- sealing the chamber;
- evacuating the chamber to create a vacuum state in the chamber;
- causing a displacement of the container positioned in the chamber to disturb the liquid crystal;
- and
- restoring the chamber to atmospheric pressure.
An apparatus for deaerating liquid crystal contained in at least one liquid crystal container, comprising:
- means for filling the liquid crystal into at least one liquid crystal container;
- means for holding the at least one liquid crystal container having the liquid crystal filled therein in a chamber;
- means for sealing the chamber;
- means for evacuating the chamber to create a vacuum state in the chamber;
- means for displacing the container to disturb the liquid crystal;
- and
- means for restoring the chamber to atmospheric pressure.
