The magic glass used for the light control unit 300 is a laminated glass structure in which an ITO film and a liquid crystal are pressed together between two sheets of glass. The light control unit may change the arrangement of molecules between the ITO film by applying a voltage to the magic glass to instantly switch from the opaque state to the transparent state, it is possible to freely change the transparency according to the change in voltage.

In the state where no voltage is applied, the liquid crystal appearing as rod-shaped molecules is aligned along the inner wall of the capsule. In this state, the light incident on the magic glass is refracted in the capsule surface or inside due to the difference in refractive index between the polymer and the liquid crystal and the birefringence of the liquid crystal. As a result, light does not go straight but scatters and appears opaque.

When a voltage is applied, the liquid crystal molecules are arranged in a direction perpendicular to the electrode because of the property of being parallel to the direction in which the voltage is applied. In this arrangement, if the refractive index coincides with the refractive index of the polymer, the liquid crystal becomes the same as that without the interface of the capsule, and the light goes straight without scattering. Thus, the magic glass looks transparent.
