<p>The apparatus comprises a light source (2), colour separating means (4) for separating a light beam (W) into three colour beams (R,G,B), three light valves (5R, 5G, 5B), a uniform illumination optical means (3) interposed between the light source (2) and the colour separating means (4) so as to convert the light beam (W) into a plurality of rectangular beams output towards the colour separating means, light guide means (9) located on the optical path of the colour beam (G) having the longest optical path, colour synthesising means (6) for synthesising the colour beams, and a projection lens (7). Three condenser lenses (101, 102, 103) are located respectively in outputting portions of the colour separating means (4) to convert the beams into almost collimated beams. The rectangular beams are superimposed to the light valves (5R, 5G, 5B) through the three condenser lenses (101, 102, 103). <IMAGE></p> |
