Abstract: A light control sheet including a light control sheet body having a front surface and a back surface, the light control sheet body including a first film including a transparent electrode layer, a second film including a transparent electrode layer, a liquid crystal layer formed between the first and second films, and a sealant covering an edge portion of the liquid crystal layer. The second film has a second film contact surface which includes a portion in contact with the liquid crystal layer, and further includes a second film outer peripheral part on which the sealant is formed, the second film outer peripheral part is extended along the edge portion of the liquid crystal layer, and when viewed in a first direction from the front surface to the back surface, the second film outer peripheral part does not overlap the first film or the liquid crystal layer.

Abstract: A light control sheet includes electrode layers including first transparent electrode layer and a second transparent electrode layer, a light control layer formed between the first and second transparent electrode layers, and transparent support layers including a first transparent support layer and a second transparent support layer such that the first transparent support layer is formed on the first transparent electrode layer on the opposite side of the light control layer and has a support surface supporting the first transparent electrode layer and that the second transparent support layer is formed the second transparent electrode layer on the opposite side of the light control layer. The first transparent electrode layer has one or more grooves extending along the support surface such that the first transparent electrode layer has an electrode element having a narrow portion formed between portions of the groove and having a width of 1 mm or more.
