The invention discloses a double-frequency bi-stable 
liquid crystal display and double-frequency bi-stable 
liquid crystal composition. The double-frequency bi-stable 
liquid crystal composition made by mixing double-frequency liquid 
crystal, chiral composition and nematic phase liquid 
crystal composition is poured into a liquid 
crystal box; through the component ratio and chemical features of the double-frequency bi-stable liquid crystal composition, the liquid crystal composition mixed has the features of both the double-frequency liquid crystal and the cholesteric phase liquid crystal, under driving of a 
frequency modulation mode, two optical statuses, namely focal conic texture and planar texture, can be converted through 
dielectric anisotropy of the liquid crystal, and an image can be displayed; thus, the double-frequency bi-stable 
liquid crystal display can be in the two optical statuses without 
voltage maintaining or decomposing the 
helix structure of the cholesteric phase liquid crystal through 
high voltage; 
dielectric conversion is not related to metastable state conversion, 
power consumption of the double-frequency bi-stable 
liquid crystal display is effectively reduced, and conversion time is effectively shortened.
