摘要： There is provided a liquid crystal composition which enables a significant reduction in crystallization temperature as compared with addition of a homolog while having a similar skeleton structure, which has an excellent compatibility, and which enables an increase in the absolute value of negative dielectric anisotropy (Δ∈). The liquid crystal composition contains two or more compounds which each have two to four ring structures between two side chains. At least one of the ring structures is a 2,3-difluorobenzene skeleton. The two side chains are bonded to different ring structures. The positions of the 2,3-difluorobenzene skeletons are different from each other, and the number of the ring structures are the same as each other.

摘要： An object of the present invention is to provide a photoalignment layer with a more reliable absorption anisotropy parameter as a photoalignment layer that allows for reduced AC image-sticking. Specifically, provided is a photoalignment layer, obtained by exposure to polarized UV radiation, that has a maximum ΔA (=A1−A2, where A1 is the absorbance in a direction parallel to a vibration direction of the polarized UV radiation, and A2 is the absorbance in a direction parallel to the vibration direction of the polarized UV radiation) of 0.35 or more per micrometer of layer thickness in a range of 230 to 380 nm.

摘要： The liquid crystal light modulator includes a first substrate (10) and a second substrate (20) disposed between two polarizers, and a pair of electrode structures (24, 24). The substrates include homeotropic alignment films (12) and (22), and at least one of the substrates has a function of aligning C-directors of liquid crystal molecules along one direction. The one direction forms an azimuth angle in the range of 35 to 55 degrees with the direction of the electric field generated by the pair of electrode structures (24, 24). A liquid crystal composition layer (31) contains a ferroelectric liquid crystal composition having a chiral smectic C phase or a liquid crystal composition that has an achiral smectic C phase and negative dielectric anisotropy. Light transmittance is modulated by the electric field generated by the electrode structures (24, 24) changing the birefringence index of the liquid crystal composition layer (31).
