ABSTRACT:
A method of filling a liquid crystal device with a blended liquid crystal material is set forth. The liquid crystal device is filled by disposing the liquid crystal device having an inlet port, in a vacuum chamber, evacuating the vacuum chamber, supplying the inlet port with the blended liquid crystal material, and elevating the pressure in the chamber to allow the blended liquid crystal material to fill the liquid crystal device through the inlet port by virtue of the differential pressure between the inside and the outside of the liquid crystal device, with the temperature of the blended liquid crystal material being maintained, until the liquid crystal device is completely filled with the blended liquid crystal material, at a temperature higher than the transition temperature of any one of the constituents of the blended liquid crystal material so that the blended liquid crystal material is transformed in its isotropic phase.
