Abstract
PURPOSE: A long-life element for dynamic scattering mode liquid crystal display that is made by using a liquid crystal composition mainly consisting of 4,4'-dialkylbenzoic phenyl ester and showing negative dielectric anisotropy, thus showing good dynamic scattering display properties such as high contrast and high response.
CONSTITUTION: More than 50wt% of at least one of 4,4'-dialkylbenzoic phenyl ester of the formula (R, R' are alkyl) is mixed with a liquid crystal of large negative dielectric anisotropy such as Schiff's base or azoquinone, when the composition is used for dynamic scattering mode displays, to give the objective liquid crystal of negative dielectric anisotropy.
EFFECT: The element has characteristics suitable for time-sharing driving and can expand the range of DS-display operating temperature toward the low-temperature side.
