Disclosed is a viewing screen (1) comprising a plate or film-like base material whose surface consists of adjacent concave or convex mirrors having the same size with the same mirror curvatures. The micromirrors of the micromirror-surface-structure (2) preferably have an elliptical contour (4) or an elongated hexagonal contour (5). The micromirrors are arranged on the surface of the viewing screen in a predetermined raster (3) with a honeycomb - shaped structure in such a way that its long half-axis is oriented verticall y. The projected light (6) is reflected in the form of an elliptical (7) or almost elliptical light cone (8) by means of the different curvatures of the micromirrors in horizontal and vertical direction. The micromirrors are spatially oriented in such a way that their optical axis intersect in a defined intersection point (18) on the viewing screen normal (26), resulting in a spatial overlapping zone (17) of all light cones reflected by the micromirrors, in which the reflected image can be seen. Little or no light i s reflected in the loss areas (19) outside said overlapping zone (17).
