1. Device for regulating the passage of energy through a surface, where the device comprises at least two switching layers S(1) and S(2), each of which comprises a liquid-crystalline medium comprising one or more dichroic compounds, and where the device comprises orientation layers O(1), O(2), O(3) and O(4), where the said switching layers and orientation layers are present in the device in mutually parallel planes in the sequence O(1), S(1), O(2), O(3), S(2), O(4),where an orientation axis OA(1)* of the molecules of the liquid-crystalline medium of S(1) which are adjacent to O(2) is present in at least one switching state of the device, and an orientation axis OA(2)* of the molecules of the liquid-crystalline medium of S(2) which are adjacent to O(3) is present, and orientation axes OA(1)* and OA(2)* are not parallel to one another and are parallel to the plane of the switching layers.
