Abstract
The invention relates to a liquid crystal device, comprising an antiferroelectric liquid crystal material (AFLC material) having smectic layers, and two substrates confining the AFLC material therebetween, wherein the AFLC material is uniaxial negative. Preferably, the AFLC material is uniaxial as a consequence of a surface stabilization and of a selected smectic tilt angle θ of the AFLC material. Preferably, the angle θ is in the range of 40°≦θ≦50°, especially 45°. The invention also relates to electrooptic liquid crystal devices.
