Abstract
PURPOSE: A liquid crystal compsn. capable of giving a positive-display, phase transition-type, guest-host color liquid crystal display improved in visibility and contrast, which obtd. by compounding a nematic liquid crystal, a dichroic pigment and a cholesteryl alkyl carbonate.
CONSTITUTION: A nematic liquid crystal, a dichroic pigment and a cholesteryl alkyl carbonate which is an optically active material of the chemical formula are mixed. The cholesteryl alkyl carbonate is cholesteryl 2-ethylhexyl carbonate, cholesteryl oleyl carbonate, etc.
