Zusammenfassung:	The screen (10) has a black color supporting layer (13) rolled on a rolling tube (11) and including a ballast at a lower edge. A white or light gray color projecting surface (12) is fixed to a supporting layer by a junction at an upper edge and on a surface of the screen for receiving a projection e.g. video image projection, where the projecting surface has smaller dimension than that of the supporting layer. The projecting surface is positioned with respect to the supporting layer, so that the lower edge is lower than the upper edge, when the screen is unrolled.
