LIGHT CONTROL SHEET
Document Type and Number:
WIPO Patent Application WO/2024/048650
Kind Code:
A1
Abstract:
A light control sheet (10) comprises a light control layer that includes a liquid crystal composition, and a first transparent electrode layer and a second transparent electrode layer as a pair of transparent electrode layers that sandwich the light control layer. The light control sheet has a first connection region (SA) in which wiring (61) for applying a voltage to the first transparent electrode layer is connected, and a second connection region (SB) in which wiring (62) for applying a voltage to a second transparent electrode layer is connected. As viewed from a position facing a surface of the light control sheet, the first connection region and the second connection region are arranged along one edge of the light control sheet. The surface resistance of each of the first transparent electrode layer and the second transparent electrode layer is 150 Ω/sq or less.
