Abstract:
A projection optical system is constituted by, in order from the reduction side, a first optical system for forming an image displayed by image display elements as an intermediate image, and a second optical system for forming the intermediate image on a magnification side conjugate plane. The second optical system is constituted by, in order from the reduction side, a first lens group having a positive refractive power, a first optical path bending means that bends an optical path with a reflective surface, a second lens group having a positive refractive power, a second optical path bending means that bends an optical path with a reflective surface, and a third lens group having a negative refractive power. Conditional Formulae (1) and (2) below are satisfied. 0.05<| f 23|/ D 223<0.50  (1) 5.0< D 212/| f |<20.0  (2).

Claim (Index 12):
The projection optical system as defined in  claim 11 , in which Conditional Formula (3-1) below is satisfied:\n 8.30< Im\u03c6\u00b7f 2/ f 2 <16.00\u2003\u2003(3-1).
