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.

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.

A color display medium is constituted by a colored polymer layer having at least two display regions of different colors, typically three colors of blue, green and red, along the extension of the polymer layer. The display regions of different colors have respectively different wavelength regions of light absorption or respectively different temperatures of thermal transition between transparent and scattering states.

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:
A display medium having a display face is composed of a plurality of display layers laminated parallel to the display face. Each display layer comprises a polymer liquid crystal having a mesomorphic temperature range between its glass transition temperature and the upper limit temperature of a liquid crystal phase used for display. The mesomorphic temperature ranges of the plurality of display layers do not overlap each other. The optical densities of the display layers are controlled independently from the other by controlling the heating temperatures and cooling rates of the display layers, and the gradation of each color can be also controlled, so that a full-color display can be realized.
