Abstract:
A head-up display device includes: an image formation unit which emits light including image information; and a projection optical system including an ocular optical system which displays a virtual image by reflecting the light emitted from the image formation unit. The ocular optical system includes spherical lenses, a free-form curved surface lens, a reflection mirror, and a free-form curved surface mirror, and is configured by arranging, in a space on the side of the ocular optical system of a plane conjugate with the virtual image plane with respect to the ocular optical system, a first small lens system which achieves first focus position movement and on which separated light from the image formation unit is made to be incident, and a second small lens system which achieves second focus position movement and on which separated light from the image formation unit is made to be incident.

Claim (Index 3):
The projection optical system according to  claim 1 ,\n wherein a virtual image distance from a first virtual image plane where a virtual image formed by the light having passed through the first small lens system is displayed to an observer of the virtual image is shorter than a virtual image distance from a second virtual image plane where a virtual image formed by the light having passed through the second small lens system is displayed to the observer of the virtual image, and the first virtual image plane is positioned closer to an end section of a field of view of the observer compared to the second virtual image plane.
