摘要： Disclosed herein is an optically active compound and a ferroelectric liquid crystal composition produced therefrom. The optically active compound has a fluorine atom introduced into the core nucleus so that it does not take on the smectic phase of a high order except for the smectic A phase and smectic C phase and which has carbonyl groups (for dipole) at adequate positions so that it exihibits greater spontaneous polarization. The ferroelectric liquid crystal composition is composed of a chiral component (including the optically active compound) and a non-chiral component, and hence it is superior in response performance.

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： Method of driving a liquid crystal display such as a ferroelectric liquid crystal display by multiplex addressing. The display has a pair of bases. A transparent electrode layer and an orientation film are formed in this order on each base. The two bases are placed opposite to each other with a certain gap between them. A ferroelectric liquid crystal material is inserted in the gap. Let Vthlow be the voltage applied when the transmittivity of the liquid crystal material begins to change. Let Vthhigh be the voltage applied when the transmittivity of the liquid crystal material substantially assumes its maximum value. First and second select pulses of opposite polarities are applied to the liquid crystal material. Let Vs1 be the voltage of the first select pulse. Let Vs2 be the voltage of the second select voltage. This method is characterized in that Vs1=±(Vthlow−&Dgr;V), where &Dgr;V>0, and that Vs2=∓(Vthhigh+&Dgr;V), where &Dgr;V>0.

摘要： A display device has a line scan driving circuit disposed in a horizontal direction of a display region and a pixel driving circuit (dot scan driving circuit) disposed in a vertical direction of the display for performing image display with pixel groups each forming one line in the vertical direction being scanned in the horizontal direction. Vertical-horizontal converting circuitry is provided for converting an image data stream supplied with n pixels in a horizontal direction and m horizontal lines in a vertical scanning direction into an image data stream with m pixels in a vertical direction and n vertical lines in a horizontal scanning direction, and the vertical-horizontal converted data is supplied to the display device by a display controlling circuit. That is, image data is supplied to the displaying device as a vertical-horizontal converted data stream and display operation is executed by vertical pixel rows being scanned in the horizontal direction, as a result of which the relatively small line scan driving circuit is disposed above or below the display region instead of the relatively large dot scan driving circuit and thus the area required for circuit mounting above/below the display region is reduced and the size of the display device in the vertical direction can be effectively reduced.
