It is important that thermal expansion anisotropy is considered significant in large size LCDs, since there will be the occurring possibility of voids in liquid crystal and alignment disordering due to volume contraction. In particular, anisotropy in smectic liquid crystals may be more remarkable than that in nematic liquid crystals, due to the movement of molecules along the layer normal direction in smectic layers. We measured the thermal expansion anisotropy of smectic layers using a simple method. Thermal expansion coefficient along the layer normal direction is about 2×10^<-5>/℃, while one that along the layer direction is about 5×10^<-4>/℃ in the Sma phase.
