Abstract

A light controlling apparatus includes first and second substrates facing each other; a first electrode on the first substrate; a second electrode on the second substrate; and a liquid crystal layer between the first electrode and the second electrode, the liquid crystal layer including cholesteric liquid crystals, wherein the cholesteric liquid crystals have a focal conic state in a light shielding mode in case where no voltage is applied, and have a homeotropic state in a transparent mode in case where a voltage is applied.
