A light control device and a transparent display including the light control device. The light control device includes: a first substrate and a second substrate facing each other; a first electrode on the first substrate; a second electrode on the second substrate; a liquid crystal layer on the Between the first electrode and the second electrode, the liquid crystal layer includes a cholesteric liquid crystal, wherein the cholesteric liquid crystal has a focal conic state in a light-shielding mode without applying a voltage, and in the When a voltage is applied, it has a vertical alignment state in the transparent mode. |
