Abstract
A light control device including a light control sheet including a light control layer switchable between at least a first state and a second state by changing alignment of liquid crystal molecules by application of a drive voltage, and transparent electrode layers sandwiching the light control layer. The light control layer is transparent in the first state and turbid in the second state. The light control layer is in the second state when there is no application of the drive voltage. When the light control layer is in the second state, the light control sheet has a transmitted image definition of 70% or less, where the transmitted image definition is based on JIS K 7374:2007 with an optical comb width set to 0.125 mm.
