| abstract | PURPOSE: To provide a stable ferroelectric liq. crystal exhibiting a high level of spontaneous polarization, which comprises a biphenyl ester compd. having a fluorine atom at an asymmetric carbon atom thereof. n CONSTITUTION: This ferroelectric liq. crystal comprises a biphenyl ester compd. having a fluorine atom at an asymmetric carbon atom thereof and represented by the formula (wherein n and m are respectively integers of 6W20 and 3W20). This liq. crystal exhibits a high level of spontaneous polarization PS and is a stable ferroelectric liq. crystal. Since the value of spontaneous polarization is sufficiently large, even if the crystal is mixed with other various types of liq. crystals so as to obtain a practical liq. crystal compsn., it is easy to attain a desired value of spontaneous polarization and to realize a high response speed. Moreover, an electro-optical element utilizing the response of the dielectric liq. crystal to the electric field of the SmC* phase has higher response speed than that of a TN-type liq. crystal element, and it is possible to provide the same with memory by the application of an appropriate orientation control method. Therefore, applications of the electro-optical element are found in a high-speed optical shutter and a display device improved in the amt. of displayed information. n COPYRIGHT: (C)1989,JPO&Japio |
