Patent ID: 8848157

Claim:
A liquid crystal display comprising: a pair of substrates including at least one transparent substrate; a liquid crystal layer disposed between the pair of substrates; and an electrode group formed on at least one of the pair of substrates so as to apply an electric field to the liquid crystal layer, wherein the liquid crystal layer contains at least one kind of liquid crystalline compound and a mixture of n kinds (n is a natural number of 2 or more) of chiral dopants, one of the n kinds of chiral dopants is a binaphthyl derivative comprising naphthyl groups acyclically joined, wherein a concentration c of the mixture of n kinds of chiral dopants is lower than a saturation solubility s of the mixture of n kinds of chiral dopants, wherein the concentration c of the mixture of n kinds of chiral dopants and a helical twisting power [HTP] of the mixture of n kinds of chiral dopants satisfy a relation of [HTP]·c≧5.5 (μm −1 ), and wherein the binaphthyl derivative is selected from a group consisting of
