1. A display device for representing two-dimensional and/or three-dimensional objects or scenes, comprising
at least one illumination device for emitting sufficiently coherent light,
at least one spatial light modulation device for modulating incident light, and
at least one optical system, where the at least one optical system is provided for multiple imaging of the at least one spatial light modulation device and for generating virtual viewing windows in accordance with the number of images of the at least one spatial light modulation device, where the individual images of the at least one spatial light modulation device are combined with one another as segments and form a field of view, where the field of view comprises at least one high-resolution holographic segment and at least one low-resolution holographic segment.
