Abstract
According to one embodiment, a light control device comprises a first liquid crystal cell includes a first liquid crystal layer, a second liquid crystal cell includes a second liquid crystal layer, and a third liquid crystal cell includes a third liquid crystal layer. The first liquid crystal layer and the third liquid crystal layer each have a first region that scatters a first polarization component and that transmits a second polarization component. The second liquid crystal layer has a third region that overlaps the first region and converts the second polarization component into the first polarization component.
