摘要： An object of the present invention is to obtain a polymer-stabilized liquid crystal composition which can suppress dependency of a driving voltage on a temperature by decreasing the driving voltage. To a low-molecular liquid crystal compound, a chiral compound, and a specific acrylate and a polymerizable liquid crystal compound as polymerizable acrylate compounds are added, to prepare a polymer-stabilized liquid crystal composition. By subjecting the polymer-stabilized liquid crystal composition to ultraviolet exposure while maintaining a desired alignment state to form a polymer chain in a liquid crystal phase, a polymer-stabilized liquid crystal display device containing a low-molecular liquid crystal in a stabilized alignment state is obtained.

摘要： A tricyclic cyclohexenyl cyclohexane derivative is disclosed. This compound is capable of lowering the .DELTA.n value of mixed liquid crystals, which have been obtained by adding said compound to nematic liquid crystals widely used as matrix liquid crystals, and elevating the N-I point thereof. Thus it is highly useful in the production of liquid crystal display cells.

摘要： A chiral nematic liquid crystal composition has minimal temperature dependency of the natural pitch and temperature dependency of the wavelength selective reflection and low temperature storage stability thereof is excellent. A chiral nematic liquid crystal composition with a broad liquid crystal temperature range is used in a bistable liquid crystal display element, and a bistable liquid crystal display element comprising the liquid crystal composition. The chiral nematic liquid crystal composition comprises optically active compounds represented by general formula (I-a) and general formula (II-a): R2P1-L1SP2-L2-P3—R3  (II-a) wherein the general formula (II-a) has the same helical twisting direction as the general formula (I-a), and shows a positive temperature dependency for the natural pitch, and a HTP value of at least 3. A bistable liquid crystal display element comprises the liquid crystal composition.
