A window (1) with an opaque coating (2) comprising a surface region (3) which has opaque surface portions (5) and which is perforated by surface portions (4) allowing light to pass through and distributed over the surface. At least one flat electroluminescent light element (EL) with several layers, including a transparent electrode (8), is placed in at least some of the opaque surface portions (5) of the surface region (3), which element, after applying an electrical supply voltage to the side of the transparent electrode (8), radiates light through at least one of the faces of the window (1).
