    • An integrally-formed polarized light converting device of a projection display unit comprises a medium of a predetermined thickness converting incident light entering at the Brewster Angle into light having a phase difference of λ/2 and a polarized light separating film reflecting a S polarized light wave and transmitting a P polarized light wave from the incident light entering at the Brewster Angle by a coated front side and a coated back side of said medium. A polarized light separating film having a coated front side reflects the S polarized light wave and transmits the P polarized light wave from the incident light entering at the Brewster Angle. The transmitted P polarized light wave has a phase difference of λ/2 when transmitted through a medium of predetermined thickness and proceeds in the same direction as the S polarized light wave reflected by the polarized light separating film.
