The magic glass used in the light control unit 300 is a laminated glass structure in which an ITO film and a liquid crystal are sandwiched between two sheets of glass. The light adjusting unit 300 can change a molecular arrangement between films by applying a voltage to a magic glass, instantly change from an opaque state to a transparent state, and change the transparency according to a change in voltage.

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

On the contrary, when a voltage is applied, the liquid crystal molecules are arranged in a direction perpendicular to the electrodes because of the property of being parallel to the direction of applying the voltage. When the liquid crystal having the refractive index coincides with the refractive index of the polymer in this arrangement state is the same as the liquid crystal having no interface of the capsule, the light is straightened without scattering. Therefore, the magic glass looks transparent.
