Abstract

PURPOSE: To obtain a TN-type display device capable of operating at low voltage and with less consumption of power, by adding 2-cyano-5-(4'-n-alkylphenyl)furan to a nematic liquid crystal substance.
CONSTITUTION: A nematic liquid crystal substance or composition is mixed with 2- cyano-5-(4'-alkylphenyl)furan of the formula. The preferable namatic liquid crystal used is a p-type liquid crystal, or a nematic liquid crystal having a liquid crystal molecule whose dielectric constant in the direction of a major axis is greater than that of a minor axis. And, the preferred amount of 2-cyano-5-(4'-alkylphenyl)furan added is approx. 5W25pts.wt. on the basis of the whole amount of the liquid crystal composition. The proportion lower than 5pts.wt. of the compound weakens the lowering effect for working voltage and the proportion higher than 25pts.wt. greatly lowers the upper limit of the range of temperature in which the liquid crystal composition is workable. Both cases are undesirable.
