    摘要: The invention concerns a smectic liquid crystal element and method of manufacture thereof. A polymer having spontaneous polarization as the liquid crystal is introduced into a liquid crystal layer of the smectic liquid crystal element in order to improve the response speed (second liquid crystal cell). The polymer has the same codes as the liquid crystal. Alternatively, a polymer having spontaneous polarization with opposite codes to the liquid crystal is introduced into a liquid crystal having a τ - V min characteristic so that a driving voltage is lowered (first liquid crystal cell). These polymers are added to a liquid crystal composite before injection into the liquid crystal cell. In a further aspect, after a photochemically polymeric monomer is added to the liquid crystal composite and the obtained product is injected into the liquid crystal cell, the monomer is polymerized by the application of light. Furthermore, the liquid crystal cell into which the polymer is introduced is heated again so as to exhibit isotropic phase and is cooled so that the tone display is realized.

    摘要: According to the present invention, a ferroelectric liquid crystal display device is provided which includes a complex made of a ferroelectric liquid crystal material and a polymer material disposed between substrates attached to each other. The substrates each have at least an electrode film and an alignment film. Furthermore, the ferroelectric liquid crystal material has a chevron layer structure, and a bending direction of the chevron layer structure is identical with a direction of a pretilt angle of all molecules of the ferroelectric liquid crystal material located at interfaces between the substrates and the ferroelectric liquid crystal material.

    摘要: A mixture of a ferroelectric or anti-ferroelectric liquid crystal material and a monomer having a single photopolymeric functional group is injected in the space between two electrode substrates while heat is applied. After cooling of the mixture it is irradiated with ultraviolet light at a temperature at which the liquid crystal material remains in the smectic phase so as to polymerise the monomer. Areas of liquid crystal material requiring different threshold voltages for switching are thereby produced. Alternatively such areas can be produced by changing the conditions applied to a mixture of liquid crystal material with a suitable dopant so as to cause separation of the dopant out of the liquid crystal material in order to provide a polarity of nucleation points for controlling domain formation within the liquid crystal material. Such control of domain formation can be used to provide greyscale in a liquid crystal device.
