Device for spatial representation and processes for their preparation

The invention relates to an apparatus for three-dimensional display and a method of manufacturing such a device. The apparatus comprises an image reproduction unit (1) with pixels x (i, j), which are arranged in a grid with rows (j) and columns (i). On the pixels x (i, j) information from at least two views A (k) with k = 2, ..., N and N is a natural number can be displayed. In sight of an observer (3) before the image reproduction unit (1) is a lenticular sheet (4) along a main direction side by side, each other alternately and periodically arranged lenticular (5) and the separation areas (6). By means of the Lentikularbereiche (5) are predetermined directions of light propagation for x of the picture elements (i, j) coming light. Thereby, the viewer (3) provides a plurality of viewing positions in front of the grid of pixels x (i, j) each with an eye at least predominantly a first selection from the views A (k) and with the other eye at least predominantly a second selection from the views a (k), so that to the viewer (3) results in a spatial visual impression. In the viewing direction of the viewer (3) (1) is also arranged an optical barrier structure (7) further in front of the image reproduction unit, with which the spatial visual impression can be improved. In such a device the barrier structure (7) next to one another, arranged in front of or behind the lenticular sheet (4) Opakbereichen with the action of a strip-shaped barrier consists. Each Opakbereich covers each have a separate area at least in part on.
