Abstract:
Shown are a liquid crystal composition having capability of achieving vertical alignment of liquid crystal molecules by action of a polymer, and a liquid crystal display device including the composition. A nematic liquid crystal composition has negative dielectric anisotropy and contains at least one polar compound selected from the group of compounds represented by formula (1) as a first additive, and the liquid crystal display device includes the composition. In formula (1), R 1  is hydrogen, halogen, alkyl having 1 to 12 carbons or the like; R 2  is a group represented by —OH, —OR 0 , —NH 2 , —NHR 0  or —N(R 0 ) 2 , in which R 0  is alkyl having 1 to 5 carbons; ring A and ring B are independently 1,4-cyclohexylene, 1,4-phenylene or the like; Z 1  is a single bond or the like; Sp 1  and Sp 2  are independently a single bond, alkylene having 1 to 7 carbons or the like; and a is 0 to 4.
