The pattern generation unit forms at least one image, and the combiner magnifies and reflects the image of the pattern generation unit to provide a virtual image. The combiner has a dynamic distortion of smaller than 0.4%, and the dynamic distortion is an average value of a maximum horizontal dynamic distortion and a maximum vertical dynamic distortion.
