摘要：
A liquid crystal display includes: a pair of substrates (601, 701) including at least one transparent substrate; a liquid crystal layer (LC) disposed between the pair of substrates (601, 701); and an electrode group formed on at least one of the pair of substrates (601, 701) so as to apply an electric field to the liquid crystal layer (LC). The liquid crystal layer (LC) contains at least one kind of liquid crystalline compound and at least one kind of chiral dopant. The concentration c of the chiral dopant is lower than a saturation solubility s thereof. The concentration c of the chiral dopant and a helical twisting power [HTP] of the chiral dopant satisfy a relation of [HTP]·c≥5.5 (µm -1 ).
