Abstract
PURPOSE: To raise the solubility of a dichroic colorant in a liquid crystal by using more than two kinds of colorants of homologs having the same basic skeletons and different and flexible side chaines for a color liquid crystal display method using a dichroic colorant.
CONSTITUTION: In a display method using two or more kinds of dichroic colorants as quests for a quest-host type color liquid crystal display, two or more kinds of colorants of homologs having the same basic skeletons and different and fiexible side chains are used. For example, two or more kinds of colorants of homologs having different side chains, e.g., of anthraquinone series, are added to a biphenyl liquid crystal, a phenylcyclohexane liquid crystal, or a Schiff base liquid crystal. The mixture of the homologs is excellent in solubility in liquid crystals, showing no crystallization phenomenon.
