Abstract:
1. A liquid crystal composition having a negative dielectric anisotropy, comprising two components, wherein the first component is at least one compound selected from the group of compounds represented by formula (1), and the second component is at least one compound selected from the group of compounds represented by formula (2): wherein R 1 , R 2 , R 3 and R 4 are each independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons or alkenyl having 2 to 12 carbons in which arbitrary hydrogen is replaced by fluorine; ring A and ring B are each independently 1,4-cyclohexylene or 1,4-phenylene; Z 1 is methyleneoxy or carbonyloxy; Z 2 is a single bond, ethylene, vinylene, methyleneoxy or carbonyloxy; and m is 1 or 2.
