Liquid crystals are being used in a variety of display devices which are based on electro-optical effects. In this paper, the liquid crystalline properties of liquid crystal materials and their molecular structure are discussed, especially from the view-point of a mesomorphic temperature range; the conductivity and temperature effects on the cut-off frequency of electrohydrodynamic instability in electrolyte-doped liquid crystals are studied to elucidate the limit in the operating temperature and frequency of liquid crystal display devices; the various orienting techniques and additives to realize the homeotropic and homogeneous alignment of liquid crystals are briefly described, and the representative electro-optical effects in liquid crystals used in display devices are surveyed.
