Abstract

PURPOSE: A stable liquid crystal composition, capable of being driven at a low voltage for a positive-type display, which is prepared by the addition of a specified compound to a liquid crystal.
CONSTITUTION: To a liquid crystal is added a compound of formula I (wherein R and R' are a 1W8C straight-chain alkyl). For example, the compound of the formula I is a compound of formula II, III, IV, etc. The compound gives no liquid crystal phase, but is capable of donating a liquid crystal dielectric anisotropy, when added to the liquid crystal even in a small amount, because it has a molecule of a bar structure and two polar groups in the direction of the short axis of the molecule. It is possible to drive the liquid crystal composition at 4.5V. It is also possible to increase the proportion of the compound of the formula I, and to drive said composition at a lower voltage, by increasing the number of components of the formula I.
