However, since each of the connecting parts exists apart from each other around the transparent layer, when placing these on the supporting part side of the light control sheet, it is necessary to support the light control sheet at two separate locations around the transparent layer. Therefore, there are restrictions on the method of supporting the light control sheet. For example, when using a light control sheet by fitting it into a window frame, both connecting parts are covered by the window frame and cannot be seen, so the negative effects caused by both connecting parts can be avoided, but when used as a partition, In particular, when a rectangular dimming sheet is installed vertically on the top of a counter for the purpose of separating customers from customers at the reception desk, one of the connecting parts should be placed on the side of the support part at the bottom. Although it can be made invisible, the other connecting part will be located on one of the three sides, and its presence will greatly impair the aesthetics and obstruct the view of the reception desk and customers.
