Abstract
An aperture covering, such as a window shade, comprises a shade body (10), a shielding member (24) provided on a shade-body periphery facing a window frame (2), and a shade-body winding mechanism (6). The shielding member (24) is conductive and contacts the window frame (2) to close the space between the shade body (10) and the window frame (2). When the winding mechanism (6) winds the shade body (10) down to cover the window frame (2) with the shade body (10), the window shade blocks electromagnetic energy inside and outside a building, while regulating light entering the building through a window.
