Abstract: The invention relates to optical device for illuminating a pixel matrix and/or a controllable spatial light modulator for a display, in particular a stereoscopic or holographic 3D display, wherein the optical device comprises a layer formed as a light waveguide, in which illumination light is guided in a light guiding layer, in particular according to the principle of total internal reflection, between two reflection layers lying opposite one another, wherein an extraction means for extracting illumination light from the light guiding layer is provided. The optical device is characterized in that the extraction means has different properties, in particular different optical properties, at a first extraction position than at another extraction position different to the first extraction position.
