ABSTRACT:
A liquid crystal apparatus has first and second liquid crystal substrates opposing each other. Segment electrodes are formed on the inner surface of the first substrate. Common electrodes are formed on the inner surface of the second substrate. Seal members seal a liquid crystal composition in a predetermined region between the segment electrodes and the common electrodes. Light shutters are formed by these electrodes and the liquid crystal composition sealed therebetween. In order to reduce influence of a hysteresis effect in the liquid crystal composition when a high frequency electric field is applied, the liquid crystal composition has a dielectric scattering phenomenon in which its dielectric anisotropy in response a low frequency electric field is larger than the absolute value of its dielectric anisotropy in response a high frequency electric field.
