Abstract
A light source device includes a plurality of light sources with different polarizations. A combined wavelength band of the light of a first polarization and second polarization is a first wavelength band. A combined wavelength band of a third polarization and fourth polarization is a second wavelength band. A plurality of selective transmission elements transmits one or more combined light of one or more polarizations and reflects one or more light of one or more polarizations. Thus, the light of the first polarization, the light of the second polarization and the light of the third polarization passing through a third selective transmission element, and the light of the fourth polarization reflected by the third selective transmission element proceed in the same direction.
