PCT No. PCT/EP85/00733 Sec. 371 Date Sep. 12, 1986 Sec. 102(e) Date Sep. 12, 1986 PCT Filed Dec. 20, 1985 PCT Pub. No. WO86/04081 PCT Pub. Date Jul. 17, 1986.The invention relates to liquid crystal phases (LC phases) having a particularly low threshold voltage, a particularly low ratio K3/K1 of the elastic constants for bending (K3) and spreading (K1) and broad nematic phase ranges, these phases containing at the same time at least one highly polar component of reduced degree of association and, to reduce the quotient K3/K1 of the elastic constants for bending (K3) and spreading (K1) of the phases to a value</=1.1, at least one apolar liquid crystal component.
