ABSTRACT:
An image display device includes a first optical modulator that modulates a plurality of color lights coming from a light source, a color combination member that combines the color lights, a second optical modulator that modulates a light provided by the color combination member as a result of the color light combination, and a relay optical system that is disposed between the color combination member and the second optical modulator. The replay optical system guides the light provided by the color combination member to the second optical modulator. A light transmissive member is disposed between the relay optical system and the second optical modulator, and allows optical path conditions from the first optical modulator to the relay optical system via the color combination member to be substantially the same as optical path conditions from the relay optical system to the second optical modulator.
