Abstract
A liquid crystal device is constituted by disposing a display layer between a pair of electrode plates. The display layer comprises a polymer having a surface energy of 25 dyn/cm or below and a low-molecular weight mesomorphic compound incompatible with the polymer. The display layer also comprises a porous film material having open pores and a low-molecular weight mesomorphic compound impregnating the porous film material, wherein the porous film material has a surface energy of 25 dyn/cm or below and is incompatible with the low-molecular weight mesomorphic compound.
