<p>The present invention relates to an image projection system (1). The system (1) comprises an illumination system (3) with a light source (5) for supplying an illumination beam. The system (1) also comprises a modulation system (11) with at least one reflecting image display panel (13, 15, 17) for modulating this light beam in conformity with image information to be projected, and a projection lens system (12) for projecting this image information. A color-separating system (19) is arranged between the modulation system (11) and the illumination system (3), and a polarizing beam splitter (9) is arranged between the color-separating system (19) and the illumination system. The reflective display panel is a liquid crystalline display panel of the diffusing type, and a lambd/4 plate (35, 37, 39) is arranged between the reflective portions of the pixels of the display panel and the polarizing beam splitter.</p> |
