摘要： A liquid crystal device is constituted by a chiral smectic liquid crystal and a pair of substrates sandwiching the chiral smectic liquid crystal therebetween and each having thereon an electrode for applying a voltage to the liquid crystal. At least one of the substrates being provided with an alignment control film comprising a specific aromatic polyimide which has been subjected to a uniaxial aligning treatment. The chiral smectic liquid crystal assumes bistability in a chiral smectic temperature range when incorporated in a test cell which is not provided with an alignment control film and has been subjected to shearing treatment. In the liquid crystal device including the polyimide alignment control film, the chiral smectic liquid crystal at least has a voltage-transmittance characteristic such that an effective tilt angle and a transmittance continuously change depending on an electric field applied thereto.

摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates including a first substrate provided with a first alignment control layer which has been subjected to a uniaxial aligning treatment and a second substrate provided with a second alignment control layer which has not been subjected to a uniaxial aligning treatment, a sealing member disposed so as to seal up a peripheral portion of the first and second substrates to form a spacing therebetween, and a dispersion member (e.g., spacer beads or adhesive particles) and a liquid crystal disposed in the spacing while contacting the first and second aligning control layers. 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 has a liquid crystal layer of a liquid crystal composition comprising a discotic mesomorphic compound and a rod-shaped mesomorphic compound. The discotic mesomorphic compound and the rod-shaped mesomorphic compound are essentially mutually different in molecular structure and refractive index anisotropy and are co-present in the liquid crystal layer in a mutual phase separation state, thus improving a light-scattering performance of the liquid crystal device.

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.
