In a rear projector with a housing on whose front side is arranged a screen for displaying a video picture, with a brightness-modulated and color-modulated R-G-B light source for emitting a light bundle, with a deflecting device for scanning this light bundle, wherein the light bundle is deflected by the deflecting device over a total angle &agr; with respect to vertical scanning, and with a deflecting mirror which is located in the housing and arranged at an angle &dgr;, wherein the light bundle exiting from a real or virtual vertex of the total deflection angle &agr; is deflected onto the screen by the deflecting mirror, the virtual or real vertex located in front of the deflecting mirror lies at a location where the smallest angle &bgr; of the light bundle to the surface of the screen during deflection is less than 20&deg; and the angle &dgr; is given by
