摘要:
A color liquid crystal display device wherein a nematic liquid crystal to which a dichroic dye and an optically active substance have been added is used as the liquid crystal layer and the amount of said optically active substance added is so selected as to fall in a range making steep the threshold voltage characteristics of the liquid crystal.
