Abstract

PURPOSE: To provide the titled device having increased light absorbance of a polychromatic dye, and capable of displaying the sign with distinct color in a highcontrast background, by adding a specific chiral nematic liquid crystal to a nematic crystal, and subjecting the liquid crystal to planar orientation by applying electrical voltage.
CONSTITUTION: A nematic liquid crystal having negative dielectric anisotropy is mixed with a polychromatic dye B and a chiral nematic liquid crystal consisting of 4-(2-methylbutyl)phenyl4'-(2-methylbutyl)-4-biphenylcarboxylate, and put into the gap between the electrodes 1 and 2. The nematic liquid crystal which is in the state of homeotropic orientation in the absence of electrical voltage, is turned to planar orientation by applying electrical voltage. The amount of the chiralnematic liquid crystal is pref. the one at which the spiral pitch of the nematic liquid crystal in the planar orientation state becomes less than two-fold of (or pref.nearly equal to) the thickness of the nematic liquid crystal.
