To obtain the subject composition having a proper value of reflectance anisotropy, a low viscosity, a large value of negative dielectric anisotropy and a wide nematic phase range and useful as a liquid crystal display element by including specific compounds.
This composition is obtained by including (A) at least one kind of compound selected from the group consisting of compounds represented by formula I (R1 is a 1-13C alkyl or a 2-10C alkenyl; R2 is a 1-10C alkyl, a 1-10C alkoxy or the like; 23 is a single bond or CH2CH2), (B) at least one kind of compound selected from the group consisting of compounds represented by formula II (R3 is same as R1; R4 is same as R2; Z2 and Z3 are each same as Z1) or the like and (C) at least one kind of compound selected from the group consisting of compounds represented by formula III (R7 is same as R1; R8 is same as R2) or the like. The amounts of the components are preferably 3-40 wt.% of the component A, 3-70 wt.% of the component B and 5-90 wt.% of the component C.
