Abstract

PURPOSE: To provide a positive type display element capable of such clear color development on an extremely white substrate as to be impossible with conventional MBBA type ones, with a liquid crystal composition of negative dielectric anisotropy comprising a cyclohexane ester type one.
CONSTITUTION: the objective display element having guest-host effect, with its host- liquid crystal comprising a cyclohexane ester type liquid crystal composition of formula (R is Cn H2n+1 alkyl; X is -OCnH2n+1 alkoxy; n is an integer: 1W6), and capable of controlling orientaticn of dichromatic dye molecules along with liquid crystal molocules, by making the dichromatic dye and the nematic liquid crystal composition lie between facing electrodes and then applying and removing electric field.
