Abstract
A light control device and a transparent display device including the same are discussed. In the light control device, a sealant uniformly spreads in a bonding process. The light control device includes a first substrate and a second substrate facing each other, a first electrode over one surface of the first substrate facing the second substrate, a second electrode over one surface of the second substrate facing the first substrate, a liquid crystal layer between the first electrode and the second electrode, a sealant sealing a plurality of liquid crystal cells between the first substrate and the second substrate, a first dam structure in a boundary between the sealant and the liquid crystal, and a second dam structure surrounding an outer side of the sealant. The liquid crystal layer transmits or blocks light, and the first dam structure surrounds an inner side of the sealant contacting the liquid crystal cells.
