Liquid crystal device and a liquid crystal material

The invention relates to a liquid crystal device, comprising an antiferroelectric liquid crystal material (AFLC material) having smectic layers, and two substrates confining said AFLC material therebetween, wherein said AFLC material is uniaxial negative. Preferably, the AFLC material is uniaxial as...

Beschreibung
Zusammenfassung:	The invention relates to a liquid crystal device, comprising an antiferroelectric liquid crystal material (AFLC material) having smectic layers, and two substrates confining said AFLC material therebetween, wherein said 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 theta of said AFLC material. Preferably, said angle theta is in the range of 40°
