The invention discloses an isothiocyano trans-cyclohexylbiphenyl liquid crystal composition and application thereof, the liquid crystal composition takes an isothiocyano trans-cyclohexylbiphenyl liquid crystal compound as a first component, the first component contains at least more than one compound shown as a structural formula (I): # imgabs0 #, R1 is selected from alkyl containing 1-10 carbon atoms or alkyl containing alkenyl; and X1-X8 are respectively and independently selected from-H,-CH3,-F or-Cl. The liquid crystal composition further comprises three or more of a second component, a third component, a fourth component and a fifth component. The birefringence value (delta n) of the liquid crystal composition is larger than 0.37, the microwave frequency insertion loss amount of the liquid crystal composition is reduced, the dielectric loss values (tan delta epsilon r, max) in 4-40 GHz are all smaller than 0.0065, the phase modulation amount (tau) is larger than 0.30, and the quality factor (mu) is large
