Abstract
A two frequency addressing liquid crystal composition wherein a plurality of liquid crystal compounds are mixed such that the absolute value of a dielectric anisotropy .DELTA..epsilon.L of the composition, measured at a low frequency 1/10 a cross-over frequency of the composition, is larger than the absolute value of a dielectric anistropy .DELTA..epsilon.H of the composition measured at a high frequency 10 times the cross-over frequency.
