| description | The invention relates to a display screen comprising a background raster (1) with light-radiating background raster elements of a first kind (2) and with light-radiating or opaque background raster elements of a second kind (3). Arranged in front of the background raster (1), as seen from the direction of a viewer, is a foreground raster (4) which features completely light-transparent foreground raster elements (5) and light-attenuating foreground raster elements (6). The foreground raster (4) is arranged at a specified distance from the background raster (1) and oriented in a specified lateral position normal to the distance, relative to the background raster (1). In such a display screen for the secure presentation of information, the completely light-transparent foreground raster elements (5) and the light-attenuating foreground raster elements (6) are, in at least one foreground area of the foreground raster (4), distributed stochastically at a ratio of about 50:50. This distribution serves as a key for e |
