Abstract:
An image projection apparatus includes a beam splitter configured to split light from a light source into first color light and second color light, a first reflective image display element configured to optically modulate the first color light, a second reflective image display element configured to optically modulate the second color light, a first parallel plate arranged between the beam splitter and the first reflective image display element and made of a large refractive index wavelength dispersion, and a second parallel plate arranged between the beam splitter and the second reflective image display element and made of a large refractive index wavelength dispersion.
