    摘要: A liquid crystal-containing precursor for a liquid crystal display device consisting of a porous polytetrafluoroethylene film which has the structure defining the pores treated with a hydrophilic substance. The pores of the treated porous film are substantially filled with liquid crystals. The hydrophilizing treatment increases the transition speed of the liquid crystals from light-scattering orientation to light-transmitting orientation. The liquid crystal-filled film can be covered with transparent non-porous layers of material, having an electrically-conductive film on at least one surface, which can be hermetically sealed at the edges, to permit long-term storage of the liquid crystals in ready-to-use sheet form and easy inclusion into a liquid crystal display device.
