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.
A liquid crystal material that has a phase system continuously showing an isotropic phase, a nematic phase, and a smectic ‘A’ phase in this order as temperature changes from a higher state to a lower state, and shows electroclinic effect in the smectic ‘A’ phase, wherein the smectic ‘A’ phase occurs at least in a temperature range from 20 degrees centigrade to 50 degrees centigrade, inclusive, wherein the liquid crystal material is a mixture of two or more liquid crystal materials that do not independently have a phase system continuo showing isotropic phase a nematic phase and a smectic ‘A’ phase in this order as temperature changes from higher state to lower state.
A liquid crystal display device having a liquid crystal layer between a pair of substrates, the liquid crystal layer containing a liquid crystal material that has a phase system continuously showing an isotropic phase, a nematic phase, and a smectic ‘A’ phase in this order as temperature changes from a higher state to a lower state and shows electroclinic effect in the smectic ‘A’ phase, wherein the smectic ‘A’ phase occurs at least in a temperature range from 20 degrees centigrade to 50 degrees centigrade, inclusive, wherein the liquid crystal material is a mixture of two or more liquid crystal materials that do not independently have 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.
A liquid crystal optical space modulation device having a liquid crystal layer between a pair of substrates, the liquid crystal layer containing a liquid crystal material that has a phase system continuously showing an isotropic phase, a nematic phase, and a smectic ‘A’ phase in this order as temperature changes from a higher state to a lower state and shows electroclinic effect in the smectic ‘A’ phase, wherein the smectic ‘A’ phase occurs at least in a temperature range from 20 degrees centigrade to 50 degrees centigrade, inclusive, wherein the liquid crystal material is a mixture of two or more liquid crystal materials that do not independently have 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.
