Claim Text:
1. A virtual image display device comprising: an image projection device that projects an image light; a bend mirror that bends the optical axis of the image light emitted from the image projection device; an optical axis converting element that converts the optical axis of the image light reflected from the bend mirror into a predetermined direction; a diverging element on which the image light emitted from the optical axis converting element is incident, spreading the image light out over a range of a predetermined angle; a lens that enlarges and emits the image light emitted from the diverging element in a direction; and a light branching element that reflects the image light emitted from the lens, while transmitting incident light from a surface other than the a reflecting surface thereof, wherein the image light from the image projection device is formed into an image on the diverging element, and wherein a virtual image of the image formed on the diverging element is generated on an extension line in an opposite direction of an emission direction of the image light reflected from the light branching element.
