Abstract
A polarizing conversion element array () of a polarization converter () has two polarizing conversion elements () provided with a polarization separating film () for separating a light beam into two linearly polarization beams and a reflecting film () that reflects one of the linearly polarization beams separated by the polarization separating film () in an alternate manner, the two polarizing conversion elements () being arranged so that the respective polarization separating films () and the reflecting films () are opposed, the polarization converter () being constructed by adhering a retardation plate () on a light-irradiation side of the polarizing conversion element array () stretching over the two polarizing conversion elements ().
