A liquid crystal composition includes a component A composed of one or more liquid crystals with negative dielectric anisotropy and a component B composed of one or more compounds selected from a general formula I, where the optical anisotropy of the liquid crystal composition is larger than 0.14. The elastic coefficient of a liquid crystal system is adjusted by introducing a bi-mesogenic compound into a negative liquid crystal or a negative liquid crystal mixture. When the liquid crystal composition is used for the dimming device, the minimum light transmittance of the dimming device in the dark state can be significantly reduced, the adjustment range of the light transmittance in the light state and the dark state can be expanded, and the haze in the dark state can be increased, thereby broadening the use range.R-MG-X-MG-R  I
