                            At least one cholesteric liquid crystal composition is mixed with at least one first nematic liquid crystal compound or composition, thereby exhibiting a TGBA phase at room temperature. The first nematic liquid crystal compound or composition preferably includes a compound having a cyano group, a halogen atom, a nitro group, a perfluoroalkoxy group or a perfluoroalkyl group at the terminal thereof. The cholesteric liquid crystal composition preferably contains a second nematic liquid crystal compound or composition and a chiral reagent.
