Abstract
A light control sheet includes a first electrode sheet including a first transparent electrode layer, a second electrode sheet including a second transparent electrode layer, and a light control layer. The first sheet, second sheet, and control layer form a driver section in which the first sheet, second sheet, and control layer are overlaid, a first non-driver section in which the first sheet is exposed from the control layer and second sheet, and a second non-driver section in which the second sheet is exposed from the control layer and first sheet. The non-driver sections have a sealing section covering end face of the control layer. The first electrode layer includes a non-conductive section in the first non-driver section. The non-conductive section is not connected to a first driver portion in the driver section. The first non-driver section includes a disconnection section separating the non-conductive section from the first driver portion.
