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.
