Abstract: A projection device is provided for displaying at least one of a two-dimensional and three-dimensional scene or of content. The projection device comprises an illumination device, at least two spatial light modulator devices and an optical system. The illumination device comprises at least one light source for generating a holographic illumination. One of said spatial light modulator devices is designed as spatial light modulator device modulating at least the phase of the light for the holographical generation of illumination patterns. This spatial light modulator device as first spatial light modulator device is followed by a second spatial light modulator device. The optical system is disposed to illuminate the second spatial light modulator device with a predefinable light distribution generated by the first spatial light modulator device.
