Abstract
The present disclosure discloses an electroresponsive liquid crystal dimming device comprising a first light transmitting conductive substrate, a first polymer network stabilized liquid crystal layer, a positive liquid crystal layer, a second polymer network stabilized liquid crystal layer and a second light transmitting conductive substrate which are arranged in sequence; and the first polymer network stabilized liquid crystal layer and the second polymer network stabilized liquid crystal layer reflect the circularly polarized light having the same polarization direction. The conversion of the positive liquid crystals in each layer between different states is driven by changing the magnitude of the access voltage of the liquid crystal dimming device according to the present disclosure, thereby realizing the adjustment of blurring to transparent states and color to colorless states of the liquid crystal dimming device, having a good application prospect in the window glass, and home glass window, and the like.
