摘要： 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.

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.
