Abstract

PURPOSE: A display element for liquid crystal having high scattering luminance and long life, exhibiting stable functions even by drive of direct current rectangular wave voltage, obtained by adding tetracyanonaphthoquinodimethane (derivative) to a nematic liquid crystal compound.
CONSTITUTION: In a display element for liquid crystal prepared by sealing up a liquid crystal compound in a space between opposing electrode base plates wherein at least one is transparent, (A) a nematic liquid crystal compound (e.g., azoxy type liquid crystal, e.g., p-ethoxy-p'-n-butylazoxybenzene shown by the formula I, etc.) wherein the direction of the dipole moment of a molecule is almost perpendicular to that of the major axis of the molecule as the liquid crystal compound is used with (B) preferably 0.01W1.0 based on component A of 11,11,12,12-tetracyano-2,6- naphthoquinodimethane shown by the formula II and its substituted compound as an electron acceptor substance, to give the desired display element for liquid crystal.
