A liquid crystal device comprises a pair of electrode plates, and a first display layer and a second display layer in contact with each other and disposed between the electrode plates, wherein said first display layer comprises a porous film having pores and a low-molecular weight mesomorphic compound filling said pores of said porous film having pores and a low-molecular weight compound filling said pores of said porous film, and said second display layer comprises the low-molecular weight mesomorphic compound. A further liquid crystal device comprises a pair of electrode plates, and a display layer disposed between the electrode plates; said display layer comprising a porous polymer film having been biaxially stretched at a stretch ratio of 1.4 - 30 for each stretching direction to provide open pores, and a low-molecular weight mesomorphic compound filling said open pores of said porous polymer film.
一种液晶装置包括一对电极板、相互接触并置于电极板之间的第一显示层和第二显示层,其中所述第一显示层包括具有孔隙的多孔薄膜和填充所述多孔薄膜孔隙的低分子量介形化合物,所述第二显示层包括低分子量介形化合物。另一种液晶装置包括一对电极板和设置在电极板之间的显示层;所述显示层包括多孔聚合物薄膜,该薄膜已经过双轴拉伸,每个拉伸方向的拉伸比为 1.4 - 30,以提供开放的孔隙,以及填充所述多孔聚合物薄膜开放孔隙的低分子量介形化合物。
