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.

摘要： A manufacturing method of a liquid crystal display element is provided with the steps of: arranging a pair of insulating substrates face to face with each other and bonding them to each other, each of the insulating substrates having electrodes formed thereon with an alignment film formed in a manner so as to cover the electrodes; and filling the gap between the two substrates with a mixture that is made by mixing a ferroelectric liquid crystal (FLC) composition with isotropic micro structural elements that locally give different threshold-value characteristics to liquid crystal molecules in the liquid crystal composition. With this arrangement, it is possible to provide a liquid crystal layer in which the isotropic micro structural elements are formed into a striped organization with the isotropic micro structural elements being sandwiched between smectic layers of the FLC composition. Consequently, it becomes possible to easily provide a liquid crystal display element with high quality that achieves a gray scale display suitable for practical use.
