Abstract

See full text

A virtual image display apparatus includes a display element, a projection lens configured to converge image light emitted from the display element, a prism configured to cause the image light by an internal reflecting surface thereof and moreover emit the image light from an emission surface thereof while refracting the image light, and a see-through mirror configured to reflect the image light emitted from the prism toward a pupil position. The projection lens, the prism, and the see-through mirror are arranged to form an off-axis system. AT an off-axis surface of the off-axis system, an intermediate pupil is arranged between the projection lens and the internal reflecting surface, with the intermediate pupil being arranged to be farther to the incident surface side of the prism than to the projection lens and the internal reflecting surface, and an intermediate image is formed between the prism and the see-through mirror.
