Abstract
The primary cause of degradation of a liquid crystal is the presence of trapped water within the liquid crystal, and the properties of a degraded liquid crystal can be recovered by removing the water from the degraded liquid crystal. A method for recovering the properties of a liquid crystal is disclosed to include a step of removing the trapped water.
