| titleOfInvention | Liquid crystal compound purification method |
| abstract | PROBLEM TO BE SOLVED: To provide a purification method for improving reliability (specific resistance, etc.) of a liquid crystal compound and reliability in a panel by a simple operation, and using the obtained compound as a constituent component. This makes it possible to prepare a liquid crystal composition having high reliability (resistivity, etc.) and reliability in the panel, and using this, a highly reliable liquid crystal display such as a simple matrix driving method or an active matrix driving method. The device is manufactured. SOLUTION: A liquid crystal compound is dissolved in an organic solvent and treated with 1,8-diazabicyclo [5.4.0] -7-undecene and / or 1,5-diazabicyclo [4.3.0] -5-nonene. And a method for purifying a liquid crystal compound characterized by removing DBN, and a liquid crystal composition using the obtained liquid crystal compound. [Effects] The reliability (specific resistance, etc.) of liquid crystal compounds and the reliability in panels, which were difficult with conventional purification methods, have been improved. Simple and easy. |
