摘要

PURPOSE:To obtain high-speed responsiveness without impairing an antiferroelectric characteristic and orientability by incorporating at least one kind of low-polymer liquid crystals and high-polymer liquid crystals which consists of low-polymer liquid crystals and high-polymer liquid crystals and exhibit an antiferroelectric liquic crystal phase. CONSTITUTION:This compsn. consists of one or =2 kinds of the low-polymer liquid crystals and one or =2 kinds of the high-polymer liquid crystals and contain =1 kinds of the low-polymer liquid crystals or high-polymer liquid crystals exhibiting the antiferroelectric characteristic. The liquid crystal optical element is formed by holding this high-polymer liquid crystal compsn. 4 in place between two sheets of electrodes 3 and 5 facing each other and has the antiferroelectric characteristic and, therefore, the distinct plural stable states are obtd. and since the element contains the high-polymer liquid crystal, the element has the excellent orientability of the liquid crystal molecules. The high-speed responsiveness with an electric field change is obtd. in this way without imparing the antiferroelectric characteristic and orientability.
