摘要： An aligning method of a chiral smectic liquid crystal includes the steps of: disposing a chiral smectic liquid crystal between a pair of electrode plates, the chiral smectic liquid crystal having a layer spacing-changing characteristic providing a layer spacing which increases on temperature decrease in a first temperature range in smectic A phase; and subjecting the chiral smectic liquid crystal to a heat treatment including a sequence of cooling from a higher temperature phase to a second temperature range in smectic A phase including at least a portion of the first temperature range, at least one cycle of heating and cooling within the second temperature range, and further cooling to a smectic phase lower than smectic phase. The heat treatment, particularly at least one cycle of heating and cooling in smectic A phase, is effective in suppressing an alignment (orientation) irregularity due to the presence of two regions different in characteristics, thus improving a drive margin.

The smectic liquid crystal is disposed to form a first region wherein the smectic liquid crystal layers are aligned to have a layer inclination angle smaller than a calculated layer inclination angle based on a temperature-dependent layer spacing-changing characteristic or are aligned in a direction perpendicular to the substrates to form a bookshelf structure, and a second region wherein the smectic liquid crystal layers are aligned to form a chevron structure having a substantial layer inclination angle or having a layer inclination angle substantially equal to a calculated layer inclination angle based on a temperature-dependent layer spacing-changing characteristic. The liquid crystal device having the first an second regions described above is effective in improving a contrast ratio and a driven margin parameter.

The dispersion member has been subjected to a surface treatment with a material constituting the second alignment control layer. The surface-treated dispersion member is effective in suppressing an occurrence of a reverse domain within a display region of the liquid crystal device, thus preventing flickering and improving a contrast.

摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates each provided with an alignment control layer, and a liquid crystal layer comprising a liquid crystal material and disposed between the substrates with a spacer member. In the device, the spacer member has an electrical conductivity larger than that of the liquid crystal material. Further, the liquid crystal layer containing the spacer member has a first resistance in a direction of a normal to the substrates in a prescribed temperature range substantially lower than a second resistance of a corresponding liquid crystal layer, in the identical direction, consisting only of the liquid crystal material and having the identical plane area and thickness. The liquid crystal device is effective in providing an improved drive margin in a wide temperature range while suppressing a DC offset voltage component applied to the liquid crystal layer.

The liquid crystal has an alignment characteristic such that it is aligned to provide an average molecular axis to be placed in a monostable alignment state under no voltage application, is tilted from the monostable alignment state in one direction when supplied with a voltage of a first polarity at a tilting angle which varies depending on magnitude of the supplied voltage, and is tilted from the monostable alignment state in the other direction when supplied with a voltage of a second polarity opposite to the first polarity at a tilting angle, said tilting angles providing maximum tilting angles &bgr;1 and &bgr;2 formed under application of the voltages of the first and second polarities, respectively, satisfying &bgr;1>&bgr;2 or &bgr;1=&bgr;2. The liquid crystal layer in the liquid crystal device is set to have a refractive index anisotropy and a layer thickness giving a retardation under voltage application which is in an optimum retardation range determined based on an arrangement of the polarizer and a wavelength of light passing through the liquid crystal layer, thus improving a resultant transmittance.
