Abstract: A display screen for secure representation of information comprising a background grid with light-emitting background grid elements of a first type and light-emitting or light-blocking background grid elements of a second type. A foreground grid (4) having completely light-transmissive foreground grid elements and light-attenuating foreground grid elements is arranged in front of the background grid. The lateral dimensions of the foreground grid elements, the distance and the lateral position of the foreground grid are matched in relation to the background grid in such a manner that a viewer looking at the foreground grid perceives coded information in a decoded form, on the basis of a contrast difference and/or color difference in relation to those fields of the background grid that are base-coded, only from one direction of view or one view angle range of up to ±50° about the view direction.
