This invention is an image display device for performing color display of an image using two spatial light modulators. The image display device has a first spatial light modulator (52) for modulating a first wavelength range component of illuminating light from an illuminating light source (10), dichroic mirrors (40), (41) for separating second and third wavelength range components of the illuminating light and condensing the respective wavelength range components, a second spatial light modulator (50) for modulating the second and third wavelength range components, and a dichroic mirror (60) for combining modulated light emitted from the first and second spatial light modulators (52), (50).
