Abstract: A liquid crystal material in which liquid crystal molecules have uniform alignment state is provided. A liquid crystal layer containing a liquid crystal material is included between a TFT array substrate and an opposed substrate. The liquid crystal material has a phase system continuously showing an isotropic phase, a nematic phase, and a smectic ‘A’ phase in this order as temperature changes from higher state to lower state and shows electroclinic effect in the smectic ‘A’ phase. As the liquid crystal material is heated (temperature is increased), the nematic phase is shown after the smectic ‘A’ phase without other phase in between, and the isotropic phase is shown after the nematic phase without other phase in between. Since the alignment state of the liquid crystal molecules becomes uniform, the transmittance is precisely controlled.
