Abstract: An energy-efficient film is provided. The film includes a first transparent substrate, a second transparent substrate, a liquid crystal layer provided between the first transparent substrate and the second transparent substrate, and a gasket provided on an outer edge of the liquid crystal layer. The gasket may also be provided on outer edges of the first transparent substrate and the second transparent substrate.
