Abstract:
A projection optical system is constituted by, in order from the reduction side, a first optical system constituted by a plurality of lenses for forming an image displayed by image display elements as an intermediate image, and a second optical system constituted by a plurality of lenses for forming the intermediate image on a magnification side conjugate plane. Conditional Formula (1), being that 0.020<enP/TL2<0.160, is satisfied, wherein enP is the distance along the optical axis from the surface most toward the magnification side in the second optical system to the position of an entrance pupil in the case that the magnification side is a light entry side, and TL2 is the distance along the optical axis from the surface most toward the reduction side in the second optical system to the surface most toward the magnification side in the second optical system.

Claim (Index 3):
A projection optical system as defined in  claim 2 , in which Conditional Formula (2-1b) below is satisfied:\n 0.138\u2264 Im\u03c6/TL 2<0.240\u2003\u2003(2-1b).
