A polarization light splitting film having a light receiving side and a
light transmitting side. The polarization light splitting film includes
an optical rotation selection layer at the light receiving side for
reflecting one of right and left circularly polarized components of a
light beam that is incident on the light receiving side and for
transmitting the other one of the right and left circular polarization
components of the light beam, and a quarter-wave layer laminated over the
optical rotation selection layer at the light transmitting side.
