Abstract:
1. A projection display apparatus comprising: a light source configured to emit light; at least one reflective liquid crystal device configured to generate an image by modulating a polarization of the light emitted from the light source and reflecting the light; an imaging lens configured to form a real image of the image generated by the reflective liquid crystal device; a quarter-wave plate disposed between the reflective liquid crystal device and the imaging lens; means for splitting image configured to include at least one reflecting plane and spatially split the real image into at least two split real images by reflecting the real image on the reflecting plane; at least two projection lenses configured to form the split real images again on a screen; and means for correcting phase difference configured to correct a phase difference between a p-polarized light and an s-polarized light generated by the reflecting plane.
