Patent ID: 7042637

Claim:
An image display device comprising: an illuminating light source for emitting illuminating light; a first spatial light modulator on which a first wavelength range component of the illuminating light becomes incident and which modulates the first wavelength range component in accordance with a pixel corresponding to the first wavelength range component; color separation and condensation means being a holographic optical element for separating second and third wavelength range components different from the first wavelength range component of the illuminating light and condensing the respective wavelength range components; a second spatial light modulator on which the second and third wavelength range components are condensed and made incident at different pixel positions corresponding to the second and third wavelength range components by the color separation and condensation means and which modulates these respective wavelength range components in accordance with pixels corresponding to the respective wavelength range components; and color combination means for combining modulated light emitted from the first and second spatial light modulators.
