    摘要: A liquid crystal device comprises a pair of substrates and a liquid crystal provided between the paired substrates wherein domains whose threshold voltages are different from one another are finely distributed throughout the liquid crystal. In particular, the respective substrates each has a transparent electrode and an alignment film formed thereon in this order and the substrates are assembled to establish a given space therebetween, and a ferroelectric liquid crystal being injected into the given space wherein domains are finely distributed as set out above, thereby providing a a liquid crystal display device. The fine distribution is such that when a transmittance through inverted domains is 25%, the number of domains (microdomains) having a size of larger than 2 &mgr;m&phgr; in a field of 1 mm2 is not smaller than 300, preferably not smaller than 600, and the width of the threshold voltage within the domains is not smaller than 2 volts within a transmittance range of from 10 to 90%. The liquid crystal device, particularly the display device, keeps a high contrast and can easily, reliably realize an analog gray-side display at low costs.

The liquid crystal element includes a plurality of base bodies each having a liquid crystal orientation film, the base bodies being opposed to each other on the orientation film side with a specific gap put therebetween; and liquid crystal disposed in the gap; wherein each of the orientation films has a property capable of relaxing polarization at an interface with the liquid crystal. The liquid crystal orientation film may be composed of an orientation film having low polarization such as a SiOx oblique vapor-deposition film or may be composed of a stacked film in which a thin film having low polarization and capable of relaxing polarization at an interface with the liquid crystal or an organic complex having an electric conductivity of 1.2×10−8 S/cm or more is stacked on an orientation film.

    摘要: A liquid crystal display device having fast response characteristics and enabling analog gray-scale display is provided. The liquid crystal display device is formed of a liquid crystal material having the chiral smectic C phase. The projection component on the substrates of the axial direction of a cone delineated by a liquid crystal molecule, and the projection component on the substrates of the axial direction of the liquid crystal molecule itself, are adapted to be coincident with the processing direction for uniaxial orientation of the substrates, this state being monostabilized as the initial state. On application of an electrical field, the liquid crystal molecule is rotated along the cone and the apparent tilt angle as viewed on the substrate surface is continuously changed in accordance with the strength of the applied electrical field. The intensity of the transmitted light is increased continuously with increasing tilt angle to obtain the continuous gray-scale or analog gray-scale.

    摘要: A driving method for a liquid crystal device includes the steps of providing a first substrate with a unidirectionally aligned data electrode group and a second substrate with a select-electrode group aligned perpendicularly to the data electrode; applying a select pulse to the select electrodes; and providing a pause corresponding to at least one line before a data-pulse sequence is applied to the data-electrode group. The select pulse can be synchronized with the data-pulse sequence by shifting them a half line relative to each other so that the select pulse and the data pulse have opposite polarity in relation to each other. Alternatively, the select pulse is applied while the data pulse sequence is applied to the data electrode group. In the latter case, the time and/or voltage is determined so as to offset the effects of the reversed electric field generated during switching of the liquid crystal.

    摘要: A functional molecular device displaying its functions under the action of an electrical field is provided. A Louis base molecule, exhibiting positive dielectric constant anisotropy or exhibiting dipole moment along the long-axis direction of the Louis base molecule, is arrayed in the form of a pendant on an electrically conductive linear or film-shaped principal-axis molecule of a conjugated system, via a metal ion capable of acting as a Louis acid. The resulting structure is changed in conformation on application of an electrical field to exhibit its function. The electrically conductive linear or film-shaped principal-axis molecule and the Louis base molecule form a complex with the metal ion. On application of the electrical field, the Louis base molecule performs a swinging movement or a seesaw movement to switch the electrical conductivity of the principal-axis molecule. This molecule exhibits electrical characteristics which may be reversed depending on whether or not the molecule has been subjected to electrical field processing. A molecular device having a function equivalent to one of CMOS may be produced from one and the same material.
