Virtual image display device

A virtual image display device comprising:

• an image display device adapted to form an image light;
• a projection optical system adapted to form a virtual image by the image light emitted from the image display device;
• and
• a light guide device including
• a light entrance section adapted to take in the image light having passed through the projection optical system,
• a light guide section adapted to guide the image light taken in from the light entrance section using total reflection on first and second total reflection surfaces extending so as to be opposed to each other, and
• a light exit section adapted to take out the image light having passed through the light guide section,
• wherein the projection optical system includes a toric optical system adapted to perform adjustment of an aspect ratio with respect to a virtual image in an image area of the image display device, the toric optical system having a plurality of lenses with flat surfaces facing an image display device side of the projection optical system, and curved surfaces on a light guide device side of the projection optical system.
