A liquid crystal medium that has stability to heat, light and so forth, a wide temperature range of a liquid crystal phase and significantly large dielectric anisotropy to develop an optically isotropic liquid crystal phase is required. Moreover, various optical devices that can be used in a wide temperature range, and have a short response time, a large contrast ratio and a low drive voltage are required.
A liquid crystal composition contains an achiral component T containing at least one compound (1) represented by formula (1) and a chiral agent to develop an optically isotropic liquid crystal phase:
(wherein, in formula (1), R
1
is alkyl having 1 to 12 carbons, L
1
, L
2
and L
3
are each independently hydrogen, fluorine or chlorine; and Y
1
is fluorine, for example).
