Abstract
A light control sheet includes transparent electrodes including a first and second transparent electrode layers, a light control layer, a transparent support layer, and a covering layer. The transparent support layer has a support surface supporting the first transparent electrode layer, the first transparent electrode layer includes a first electrode element and a second electrode element aligned along the support surface and electrically insulated from each other by a groove extending in a direction along the support surface of the transparent support layer and that the groove is penetrating through the transparent support layer and the first transparent electrode layer in a depth direction of the groove and has an opening on the protected surface of the transparent support layer, and the covering layer is formed such that the covering layer is covering the opening of the groove formed in the transparent support layer and the first transparent electrode layer.
