    Abstract: A liquid crystal composition exhibiting a blue phase, which enables higher contrast, and a liquid crystal display device including the liquid crystal composition. The liquid crystal composition contains a chiral agent and liquid crystal containing a compound having three electron-withdrawing groups as end groups of a structure where a plurality of rings including at least one aromatic ring is linked to each other directly or with a linking group laid therebetween. At least one of the three electron-withdrawing groups includes a trifluoromethyl group. The peak of the diffracted wavelength on the longest wavelength side in the reflectance spectrum of the liquid crystal composition is less than or equal to 450 nm, preferably less than or equal to 420 nm. Furthermore, a liquid crystal display device can be provided with the use of the liquid crystal composition.
