Title: COMPOSITION AND METHOD FOR COMPOSITION STORAGE
Abstract:
The present invention is a composition held in an airtight container and containing substantially one type of liquid crystal compound and an additive that prevents deterioration of the liquid crystal compound, and the present invention provides a liquid crystal composition that uses a liquid crystal compound obtained by this production method. The present invention is also a simple recrystallization method that yields a liquid crystal compound having high specific resistance. According to the present invention, substantially one type of liquid crystal compound can be subjected to long-term storage while maintaining a high purity level. By mixing the liquid crystal compound according to the present invention with another liquid crystal compound, a highly stable liquid crystal composition is obtained and a liquid crystal display element having an excellent reliability is also obtained.
