Abstract
PURPOSE: To enhance lightness, increse response speed and perform distinct color displaying by performing parallel orientation surface treatment to the inside surfaces of electrode substrates through the use of liquid crystal having dispersion type dielectric anisotropy for the liquid crystal.
CONSTITUTION: A liquid crystal panel 6 sandwiching the liquid crystal 1 added with multichromatic dyes between a pair of glass substrates 4, 5 provided with transparent electrodes 2, 3 at one side, a light scattering plate 7 installed behind the panel 6 and a power source of the electrodes 2, 3 are provided. Mixed cholesteric liquid crystals containing nematic liquid crystal material having dispersion type dielectric anisotropy and cholesteric liquid crystal material are used for the liquid crystal 1. The dielectric anisotropy Δε of the mixed liquid crystals exhibits dispersion type characteristics in which the polarity of Δε varies with the frequencies of the applied electric field. Parallel orientation treatment through coating of surface active agents has been applied on the inside surfaces of the substrates 4, 5 provided with the electrodes 2, 3. As a result, distinct color displaying may be accomplished without using any linearly polarized plate.
