摘要： A liquid crystal device comprising a pair of parallel base plates and a ferroelectric liquid crystal disposed between the base plates. One of the pair of parallel base plates is provided with a plurality of stepwise elevations disposed in the form of stripes, and has been implemented with a uniaxial orientation treatment in a direction parallel to the edges of the stepwise elevations. The stepwise elevation may be formed by a transparent electrode alone or in combination with an alignment control film disposed thereon. Because of the above features, alignment defects liable to develop from the edges of the elevations are removed.

摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates respectively having thereon a group of stripe-shaped scanning electrodes and a group of stripe-shaped data electrodes disposed to intersect the scanning electrodes and a liquid crystal disposed between the scanning electrodes and the data electrodes so as to form a pixel at each intersection of the scanning electrodes and the data electrodes. The liquid crystal device is driven by applying a scanning selection signal sequentially to the scanning electrodes, and applying data signals to the data electrodes while phase modulating the data signals depending on given gradation data. One unit period of data signal is divided into plural sections, the data signals in each section are phase-modulated in one direction in accordance with an increase in gradation data, and the data signals in mutually adjacent sections are phase-modulated in mutually opposite directions in accordance with an increase in gradation data.

摘要： A liquid crystal cell is constituted a pair of substrates each having an electrode thereon and disposed with their faces having the electrode opposite to each other, a spacer and a particulate adhesive disposed to leave a spacing between the substrates, and a liquid crystal disposed to fill the spacing between the substrates. The particulate adhesive is dispersed at a higher density in a region close to a side of the cell than in a central region of the cell, particularly in a direction of unidirectional alignment axis provided to the substrates. By such uneven distribution of the particulate adhesive, undesirable local thickening of the cell side due to movement of liquid crystal molecules during drive can be suppressed.
