Abstract:
1. A projector comprising: a light source; a polarization conversion unit that converts the light flux from the light source into polarized light having a plane of polarization parallel to a first direction; a color separation/light guiding system including a separating surface and at least one optical-path deflecting mirror, the separating surface separating the polarized light having exited from the polarization conversion unit into light fluxes having different wavelength bands, the separating surface being disposed in such a way that the plane of incidence of the polarized light with respect to the separating surface is perpendicular to the first direction, the at least one optical-path deflecting mirror deflecting the corresponding one of the light fluxes having traveled via the separating surface, the at least one optical-path deflecting mirror being disposed in such a way that the plane of incidence of the corresponding polarized light flux having traveled via the separating surface with respect to the optical-path deflecting mirror is parallel to the first direction; and a plurality of light modulators illuminated with the respective light fluxes separated by the color separation/light guiding system.
