Abstract
A liquid crystal element improved to reduce hysteresis and after-image by relaxing electronic polarization at an interface between liquid crystal and an orientation film, and hence to enhance an image quality and realize smooth display of a dynamic image irrespective of a material of liquid crystal. The liquid crystal element includes a plurality of base bodies each having a liquid crystal orientation film, the base bodies being opposed to each other on the orientation film side with a specific gap put therebetween; and liquid crystal disposed in the gap; wherein each of the orientation films has a property capable of relaxing polarization at an interface with the liquid crystal. The liquid crystal orientation film may be composed of an orientation film having low polarization such as a SiOx oblique vapor-deposition film or may be composed of a stacked film in which a thin film having low polarization and capable of relaxing polarization at an interface with the liquid crystal or an organic complex having an electric conductivity of 1.2.times.10.sup.-8 S/cm or more is stacked on an orientation film.
