摘要： A liquid crystal display device includes, in sequence, a backlight, a first substrate including a color filter layer, a liquid crystal layer containing a liquid crystal composition, and a second substrate. The liquid crystal composition contains a liquid crystal compound having a phenyl group and a conjugated bond group. The phenyl group has a halogen atom substituted for at least one hydrogen atom. The conjugated bond group is conjugated with the phenyl group to form a continuous conjugated system.

摘要： The present invention provides a compound represented by formula (i), a liquid crystal composition using the compound, and a liquid crystal display device using the liquid crystal composition. The compound represented by formula (i) has a partial structure Ki1 represented by any of general formulas (K-1) to (K-17) and further has ring B having at least two P-Sp- groups. Therefore, when used for a liquid crystal composition, the compound adsorbs to substrates sandwiching the liquid crystal composition (liquid crystal layer) and allows liquid crystal molecules to be held such that they are aligned in a vertical direction without a PI layer, and improved alignment stability and low-temperature storage stability can be achieved.
