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： An optical modulation device comprises scanning electrodes and signal electrodes disposed opposite to and intersecting with the signal electrodes, and an optical modulation material disposed between the electrodes, a pixel being formed at each intersection of the electrodes and showing a contrast depending on the polarity of a voltage applied thereto. The device is driven by a method comprising, in a writing period for writing in all or prescribed pixels among the pixels on a selected scanning electrode, a first phase for applying a voltage of one polarity having an amplitude exceeding a first threshold voltage of the optical modulation material to the all or prescribed pixels, and a second phase for applying a voltage of the other polarity having an amplitude exceeding a second threshold voltage of the optical modulation material to a selected pixel and applying a voltage not exceeding the threshold voltages of the optical modulation material to the other pixels, respectively among the all or prescribed pixels. The duration of a continually applied voltage of the same polarity applied to a pixel on a scanning electrode is 2.5 times the duration of the first phase in the writing period at the maximum.
