Abstract
A liquid crystal composition that contains achiral component T including at least one compound selected from the group of compounds represented by formula (1) and at least one compound selected from the group of compounds represented by formula (2), and a chiral agent to develop an optically isotropic liquid crystal phase. In formulas (1) and (2), R1 and R2 are independently alkoxyalkyl; Z11, Z12, Z21 and Z22 are independently a single bond; L11 to L13, L21 and L22 are independently fluorine; and Y1 and Y2 are independently fluorine, for example.

A liquid crystal composition that contains achiral component T including at least one compound selected from compounds represented by formula (1) and at least one compound selected from compounds represented by formula (2), and a chiral agent to develop an optically isotropic liquid crystal phase:
- wherein, in formulas (1) and (2), R1 and R2 are independently alkyl having 1 to 12 carbons, alkenyl having 2 to 12 carbons, alkynyl having 2 to 12 carbons, alkoxy having 1 to 11 carbons, or alkoxyalkyl in which a total of the number of carbons is 1 to 12, in which at least one of R1 and R2 is alkoxyalkyl in which a total of the number of carbons is 1 to 12;
- Z11, Z12, Z21 and Z22 are independently a single bond, —COO— and —CF2O—, in which one of Z11 and Z12 is —CF2O— or —COO—, and the other is a single bond, and one of Z21 and Z22 is —CF2O— or —COO—, and the other is a single bond;
- L11 to L13, L21 and L22 are independently hydrogen, fluorine or chlorine;
- and Y1 and Y2 are independently fluorine, chlorine, —CF3 or —OCF3.
