The invention provides a liquid crystal (LC) composition, a LC cell thereof, and a LC device thereof. The LC composition comprises (i) a mixture of two or more nematic liquid crystals, and (ii) at least one chiral dopant. The mixture of the liquid crystals can exist in a blue phase within a temperature range of from about 12-60&#xb0; C. such as 21-28&#xb0; C. The LC device can be a blue phase mode liquid crystal display (BPLCD) based on such a room-temperature blue phase LC. The BPLCD requires no alignment, and it exhibits merits such as a fast switching time (e.g. sub-millisecond), a low switching voltage and a large field-induced birefringence, among others.
