摘要： A chiral smectic main chain-type polymer liquid crystal includes mesogen units and a flexible chain group connecting the mesogen units having a length equal to or longer than 1,4-butylene group. The polymer liquid crystal is also characterized by having at least two units having mutually different optically active groups and having at least two recurring units which show mutually reverse helical rotations in its chiral smectic phase. Because of these features, the polymer liquid crystal can show an improved responsiveness because of its chiral smectic ferroelectricity based on an elongated helical pitch while retaining a good film-formability of a main chain-type polymer liquid crystal.

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.

摘要： An image forming medium is constituted by a laminate including at least an optical scattering layer and a backing member preferably comprising a pattened color filter. The laminate is composed to have an interface between the optical scattering layer and the backing member capable of reflecting light incident to the optical scattering layer. The optical scattering layer may comprise a polymer liquid crystal optionally containing a fluorescent agent or nucleating agent so as to enhance the optical scattering effect. The interface may be given by a low-refractive index layer, such as air layer. The optical scattering layer and the backing member can be separated and combined with an adjusting means for adjusting the relative position of the optical scattering layer and the backing member to provide an image forming apparatus.

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.
