ABSTRACT:
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.
