摘要： A liquid crystal device showing improved uniform alignment characteristic and switching characteristic is constituted by a pair of an upper substrate and a lower substrate, and a chiral smectic liquid crystal disposed between the upper and lower substrates. Each of the upper and lower substrates has thereon an electrode for applying a voltage to the liquid crystal and a uniaxial alignment film. The alignment films on the upper and lower substrates are provided with uniaxial alignment axes which cross each other so that the direction of crossing of the uniaxial alignment axes from the lower substrate to the upper substrate is identical to the direction of helical twist in cholesteric phase of the chiral smectic liquid crystal, and the chiral smectic liquid crystal is disposed in such an alignment state that the liquid crystal shows a pretilt angle .alpha., a cone angle H, an inclination angle .delta. of SmC.sup.* layer, and an apparent tilt angle .theta.a satisfying relationships of: H .theta.a>H/2. The crossing direction may preferably have a polarity (taken as "positive" in clockwise direction and "negative" in anticlockwise direction) which is the same as the polarity of the spontaneous polarization of the liquid crystal.

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.
