Abstract
A liquid crystal device is constituted by disposing a display layer between a pair of electrode plates. The display layer comprises a mesomorphic polymer and a low-molecular weight mesomorphic compound. The mesomorphic polymer may preferably be a main chain-type mesomorphic polymer having an ester linkage or a mesomorphic polymer derived from a polymerizable mesomorphic compound. The display layer may preferably comprise a mesomorphic polymer having a dielectric anisotropy .DELTA..epsilon. of -3.0 or below and a low-molecular weight mesomorphic compound incompatible with the mesomorphic polymer and having a positive dielectric anisotropy.
