Provided is a liquid crystal material applied to a multi-response-mode smart window and an application thereof. The present disclosure relates to a liquid crystal material and an application thereof. The problem of high drive voltage of the liquid crystal smart window based on dynamic scattering mode in the prior arts can be solved. The liquid crystal material applied to the multi-response-mode smart window is formed by mixing a dichroic dye, an ionic dopant and a liquid crystal. It is applied to preparing an electrohydrodynamics liquid crystal dimming device which is capable of switching among transparent state, light-absorbing state and scattering state under a drive voltage of 5V to 50V and a drive frequency of 1 Hz to 5 kHz.
