摘要： A projecting device includes a first projective optical system forming an intermediate image having trapezoidal distortion from light emitted by a display unit displaying a rectangular image, a second projective optical system projecting the light from the intermediate image obliquely onto a screen so that an enlarged image in which the trapezoidal distortion has been corrected will be projected on the screen, and an intermediate optical system leading the light to combine the two projective optical systems. The second projective optical system includes at least one lens having a surface on which first and second ray bundles emitted from both ends of the image displayed by the display unit in regard to a short side direction of the image are totally separate from each other. A prescribed lens included in the at least one lens is configured so that gradients and curvatures at particular positions will satisfy prescribed conditions.

The first lens group and the second lens group have a positive power and a negative power, respectively. The first deflecting system is located over the first optical system in a cross sectional plane. The first deflecting system deflects the light beam in a direction moving away from the screen to direct the light beam to the second optical system.
