ABSTRACT:
The liquid crystal device is constituted by disposing a display layer between a pair of electrode plates. The display layer comprises a stretched porous polymer film having open pores and a low-molecular weight mesomorphic compound impregnating the polymer film. The display layer further comprises a porous polymer film having a three dimensional network structure characterized by a fibril diameter of at most 0.3 micron, and a low-molecular weight mesomorphic compound impregnating the polymer film. The display layer still further comprises a first display layer comprising a porous film and a low-molecular weight mesomorphic compound impregnating the porous film, and a second display layer comprising the low-molecular weight mesomorphic compound.
