<p>A projector comprises a light source (22) that emits illuminating light (L), a single modulation panel (30), a projection optical system (40), a color filter mechanism (26), a converging optical system (24) that converges the illuminating light (L) on a filter surface of the color filter mechanism (26), and a controller (100) for controlling the color filter mechanism (26) and the single modulation panel (30). The color filter mechanism (26) includes a rotatable filter rotor (50) having a plurality of color filters (50R; 50G; 50B) and a plurality of light-blocking mask bands (51) provided at the boundaries of the color filters (50R; 50G; 50B), and a filter driver (54) that rotates the filter rotor (50). The converging optical system (24) converges the illuminating light (L) such that the size of the illuminating light spot on the filter surface is smaller than the individual color filters (50R; 50G; 50B). <IMAGE></p> |
