Abstract: A system for displaying pictures in a rear projection television set including projection optics (2) disposed in the housing of the television set and connected to an illumination unit (1), with a picture transmitter (13) having a digital tilt mirror matrix (DMD matrix), the picture modulated by the picture transmitter (13) being projected by the projection optics (2) onto the rear side of a screen (7). The projection optics (2) include a first and second part optics (8, 9) lying on a common optical axis (11) that are provided at the same time for illumination. The light coming from the illumination unit passes via third part optics (10) and via at least one deflection element (15) into the second part optics (9). In the optical path of the front region of the projection optics an “off axis” mirror (5) and at least one deflection element (15) bend the optical path.
