Abstract
According to one embodiment, a light control device includes a first liquid crystal cell including a first liquid crystal layer, a second liquid crystal cell including a second liquid crystal layer, and a polarization conversion element. The first liquid crystal layer and the second liquid crystal layer each includes a first region which scatters a first polarized component and transmits a second polarized component and a second region which transmits the first polarized component and scatters the second polarized component. The polarization conversion element overlaps the first region and the second region, converts the first polarized component into the second polarized component, and converts the second polarized component into the first polarized component.
