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, a first optical path bending means that bends an optical path with a reflective surface, 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 second optical path bending means that bends an optical path with a reflective surface, and a second lens group having a positive refractive power. Conditional Formulae (1) and (2) below are satisfied. 10.0< TL 1/| f |<50.0  (1) 4.0< TL 21/| f |<30.0  (2).

Claim (Index 13):
A projection optical system as defined in  claim 1 , wherein:\n the intermediate image is configured such that the peripheral portion has more field curvature toward the first optical system than the portion thereof at the center of the optical axis.
