ABSTRACT:
A liquid crystal device suitable as a display device is produced through a process wherein a chiral smectic liquid crystal is injected into a blank cell in a temperature where two higher temperature phases, such as isotropic phase and cholesteric phase or cholesteric phase and smectic A phase, of the liquid crystal are co-present. As a result, the liquid crystal injection is completed in a relatively short period to provide the liquid crystal device with a uniform alignment characteristic of the liquid crystal.
