Abstract:
A display device for representing two-dimensional and/or three-dimensional objects or scenes, having at least one spatial light modulation device having pixels for modulating light, at least one optical system, and at least one light guiding device. Light beams originating from the individual pixels of the spatial light modulation device are incident on the at least one light guiding device at different angles on average in relation to the surface of the at least one light guiding device and can be coupled therein, whereby a coupling angular spectrum is definable. The light beams propagating in the at least one light guiding device can be coupled out of the at least one light guiding device at different angles on average in relation to an observer region, whereby a decoupling angular spectrum is definable. The decoupling angular spectrum is enlarged in comparison to the coupling angular spectrum.
