摘要： The liquid crystal device is constituted by disposing a display layer between a pair of electrode plates. The display layer comprises a porous polymer material having open pores partially filled and a low-molecular weight mesomorphic compound impregnating the porous polymer material. The display layer is free from an unfilled portion of the low-molecular weight mesomorphic compound to be effective for providing a liquid crystal device showing a high transmittance and a good contrast. The display layer also comprises a three dimensional network structure coated with a polymer layer, and a low-molecular weight mesomorphic compound impregnating the three-dimensional network structure. The display layer is free from a fibrous part which is unstable against an applied voltage to be effective for providing a liquid crystal device showing no hysteresis.

摘要： A recording medium having a recording layer comprising a polymer liquid crystal is used for multivalue recording by using at least two different liquid crystal phases at least two levels of locally different liquid crystal proportion, or thicknesswise difference in an optical variable, such as transmittance a reflectance, generally through controlled heating and cooling. In effecting the recording, two heating sources may suitably be used, one for imagewise heating and the other for supplemental heating.

摘要： An optical modulation device is provided by forming an optical modulation layer comprising a polymer liquid crystal having a helical structure and a non-helical structure in chiral smectic C phase. The helical structure of the polymer liquid crystal is selectively formed or removed to provide a recorded state. The recorded state is held below the glass transition point of the polymer liquid crystal. The helical pitch of the helical structure can be selectively changed to form a recorded state. The helical structure can be formed to dispose its principal axis perpendicularly to the polymer liquid crystal layer. The recorded state may be read out by detecting a reflectance from the polymer liquid crystal layer.
