Abstract
A nematic liquid crystal composition having an improved response to a pulsating driving voltage for effecting a dynamic scattering mode which comprises a predominant amount of a nematic liquid crytal having properties of the dynamic scattering mode and 0.001 to 3% by weight of an onium halide salt having a nitrogen atom as a nucleus, the composition further containing a phenolic compound for improving the solubility of the onium halide salt in the lqiuid crystal and assisting in increasing the degree of dissociation of the neutral onium halide salt to ions.
