摘要： A color image forming method provides clear color images with good color balance by thermally controlling a thermosensitive medium, such as polymer liquid crystal. The medium is capable of reversibly assuming optical states of being transparent and of scattering light, and allows picture-element display areas in at least two colors to be composed on a surface thereof. Picture elements within color areas are selected if they correspond to the color whose spectral transmission center is, among those of the colors to be displayed, closest to the longest wavelength involved. Heat is applied such that the maximum haze degree of the selected picture elements is greater than that of picture elements corresponding to any of the other colors.

摘要： A polymer liquid crystal device is formed by a color polymer liquid crystal layer, generally disposed on a substrate. The color polymer liquid crystal layer includes a plurality of minute polymer liquid crystal elements, which in turn comprise plural species of color polymer liquid crystals colored in at least two colors and disposed regularly or irregularly in the layer so that the polymer liquid crystal elements emit scattered light in intensities which are selectively controlled thermally to effect a display with scattered light. In the color polymer liquid crystal layer, a color of the polymer liquid crystal elements emitting the longest wavelength scattered light are disposed in a larger areal proportion than the other color of the polymer liquid crystal elements so as to correct color balance in compensation for a difference in spectral luminous efficiency or differences in scattering intensity and scattering angle depending on colors during a display using scattered light.

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： 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.
