VIRTUAL IMAGE DISPLAY DEVICE

摘要

A virtual image display device includes: an image projection device that projects an image light; a diverging element on which the image light emitted from the image projection device is incident, spreading the image light out over a range of a predetermined angle; and a light branching element that reflects the image light emitted from the diverging element, while transmitting the incident light from the surface other than the reflecting surface. The image light from the image projection device is formed into an image on the diverging element. A virtual image of the image formed on the diverging element is generated on an extension line in the opposite direction to the emission direction of the image light reflected from the light branching element. Further, an optical axis converting element is provided to convert the optical axis of the image light emitted from the image projection device, into a predetermined direction.

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; and a light branching element that reflects the image light emitted from the lens, while transmitting the incident light from the surface other than the reflecting surface, wherein the image light from the image projection device is formed into an image on the diverging element, wherein a virtual image of the image formed on the diverging element is generated on an extension line in the opposite direction of the emission direction of the image light reflected from the light branching element.
