    Abstract: A packaging body for a light control sheet including a light control sheet, and a packaging member that supports the light control sheet. The light control sheet includes a first transparent electrode film, a second transparent electrode film, a sealing section that seals a gap between the first transparent electrode film and the second transparent electrode film in an outer peripheral section of the light control sheet, and a liquid crystal composition that is enclosed in the gap surrounded by the sealing section. The packaging body includes an easy-peel tape that covers the sealing section and fixes the sealing section to the packaging member. This allows the packaging body for the light control sheet to protect the quality of the light control sheet.
