ABSTRACT:
The twistable liquid crystal phases contain at least two chiral compounds (admixtures), at least one exhibiting helix inversion and at least one other having a high twisting capacity. With the aid of this combination of chiral compounds possessing certain properties, it is possible to effect temperature compensation with a relatively small amount of added admixtures.
