摘要： An optically active 2-fluoro-1-alkanol compound represented by the formula (Ia): ##STR1## wherein R is an alkyl group having 1-16 carbon atoms, and C* is an asymmetric carbon atom; and an optically active compound derived from the fluoroalkanol and represented by the formula (Ib): ##STR2## wherein R and C* are the same as above, m is 1 or 2, n is 0 or 1, and A is a releasable substituent. Because of the fluorine atom directly attached to an asymmetric carbon atom, these compounds are particularly effective in increasing a spontaneous polarization, improving a electric field responsive characteristic of a liquid crystal composition, and controlling the liquid crystal state.

摘要： Orientation of a liquid crystal is controlled by first forming a phase boundary of the liquid crystal between a monoaxially anisotropic phase where the liquid crystal molecules are aligned in one direction and a higher temperature phase between a pair of base plates, transforming a part of the higher temperature phase adjacent to the phase boundary under cooling into the monoaxially anisotropic phase where liquid crystal molecules are aligned in parallel with the liquid crystal molecules in the already formed monoaxially anisotropic phase, and successively causing the phase transformation in the direction perpendicular to the phase boundary.

摘要： An optical modulation apparatus has a matrix electrode arrangement comprising scanning electrodes and signal electrodes oppositely spaced from the scanning electrodes. Scanning signals are selectively applied sequentially and periodically to the scanning electrodes and information signals are selectively applied to the signal electrodes in synchronism with the scanning signals to effect optical modulation of an optical modulation material showing a first stable state and a second stable state with respect to an electric field applied thereto interposed between the scanning and signal electrodes. Before or after an information signal is applied to a selected signal electrode in synchronism with a scanning signal applied to a selected scanning electrode, an auxiliary signal different from the information signal is applied to the selected signal electrode in synchronism with the scanning signal, and an amplitude of a writing voltage applied to an intersection of the selected scanning electrode and the selected signal electrode is two or more times that of a first non-writing voltage applied to an intersection of a non-selected scanning electrode and the selected signal electrode. The amplitudes of the writing voltage and the first non-writing voltage are respectively determined with respect to a reference voltage determined as a difference between a voltage applied to a signal electrode receiving no data signal, and a voltage applied to the non-selected scanning electrode.
