Abstract
Provided are a liquid-crystal-medium having stability to heat, light and so forth, a wide liquid-crystal-phase temperature-range and significantly large dielectric-anisotropy and developing an optically isotropic liquid-crystal-phase; and various optical-devices used in a wide temperature-range, having short response-time, a large contrast-ratio and low drive-voltage and suppressing decrease in an effective dielectric-constant in a high-frequency range. A Liquid-crystal composition contains achiral-component T containing at least one compound selected from a first component represented by formula (1) and at least one compound selected from a second component represented by formula (2) or (3) and a chiral-agent to develop optically-isotropic liquid-crystal-phase: In formula (1), R: alkyl, ring A: 1,4-cyclohexylene, ring B: 1,4-phenylene, Lto L: fluorine, Y: fluorine, n: 1 or 2, R: alkyl, Zand Z: single-bond or —CFO—, Lto L: fluorine, Y: fluorine, R: alkyl, Zand Z: single-bond or —CFO—, Lto L: fluorine, Y: fluorine, for example.
