Claim 5:
6. The optical system as recited in claim 5, wherein the beam splitter comprises a polarizing beam splitting film and a polarizing film, wherein the polarizing beam splitting film is configured to allow polarized light, whose polarization is in the first direction, to be transmitted and polarized light, whose polarization is in the second direction to be reflected, wherein the polarizing film is configured to allow polarized light, whose polarization is in the first direction, to be transmitted and polarized light, whose polarization is in the second direction, to be absorbed, and wherein viewed in a direction of the light emitted from the image source, the polarizing beam splitting film is located upstream of the polarizing film to define the beam splitting side.
