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.

Abstract: A microfluidic chip includes an input section from which a liquid is introduced, a channel section in which the liquid flows, and an output section from which the liquid is discharged or a drug fixation section where the liquid and a drug come into contact. The channel section has a hydrophobic region in which a contact angle of a surface in contact with the liquid is 90 degrees or more and 130 degrees or less. The channel section is formed by being surrounded by at least a floor layer, a barrier layer, and an upper covering layer above a substrate, and a surface of at least one of the floor layer, the barrier layer, and the upper covering layer has the hydrophobic region.
