Abstract

PURPOSE:To improve the response of a liquid crystal element to heat or the response speed in a smectic A phase and nematic phase by using a ferroelectric liquid crystal for the liquid crystal. CONSTITUTION:The ferroelectric liquid crystal is used for the liquid crystal layer 108 of the thermal scanning type liquid crystal element which executes writing and erasing of images by the thermoptical effect of the liquid crystal indicating a smectic intermediate layer in a specified temp. range. Namely, the liquid crystal which exhibits the ferroelectric smectic C* liquid crystal phase and has other nematic phases (for example, SnB, SmH*SmI*) at the immediate lower temp. thereof is used. The liquid crystal element, therefore, attains either state of bistable states according to the change in the polarity of the voltage pulses to be impressed thereto; thereafter, the liquid crystal element is gradually cooled while an electric field is impressed thereto so that the liquid crystal transfer to the other nematic phase of the lower temp., but the molecular axis direction of the liquid crystal is maintained as it is. The liquid crystal element which does not require temp. control, has the excellent advantage in the high response speed and has a high contrast and a large quantity of transmitted light is thereby obtd.
