ABSTRACT:
A color wheel (35) has equally arranged RGB primary color filters, and intermediate color filters each arranged between adjacent primary color filters. A time division driver (39) drives a spatial light modulator (31) by supplying color signals corresponding to color of the lights from the color wheel (35) to the spatial light modulator (31). The time division driver (39) controls the spatial light modulator (31) in accordance with display control instructed by a control unit (14). Since the intermediate color filters are arranged between the adjacent primary color filters, a projector engine (13) projects mixed color lights during color mixture terms where the primary color and the intermediate color are mixed, thus improves the color reproduction performance.
