Virtual image display device

A virtual image display device that projects an image on a projection target member to form a virtual image opposing an observer via the projection target member, the virtual image display device comprising:

• a projection member that projects the image;
• and
• a projection optical system that leads the image to the projection target member to form the virtual image,
• wherein
• a virtual image distance VID from a center of a visual recognition area of the observer to a center of the virtual image is not less than 2,500 mm,
• the projection optical system includes, in order from the projection member to the virtual image:
• a first optical element being either one of a lens element and a reflector;
• and
• a final reflector,
• a reflection surface of the final reflector satisfies Conditional Relation 1, on an optical path extending from the projection member to the virtual image:
• 10°≤|θz max−θz min|≤30° Conditional Relation 1
• where:
• θz is an angle between a normal vector perpendicular to a tangent plane passing through an origin of a definitional equation defining a shape of the final reflector and a normal vector with respect to a tangent plane at any given point on the final reflector;
• θz max is a maximum value of θz;
• and
• θz min is a minimum value of θz.
