Then, since the front surface 32a and the back surface 32b are non-parallel, a difference in direction (angle) occurs between the first ray L1 and the second ray L2 toward the user E.

Therefore, it is possible to prevent the occurrence of a situation in which the user E cannot focus on the virtual image. Therefore, according to the present embodiment, the distance from the concave mirror 16 to the display unit 14 is fixed, and the change in the distance from the concave mirror 16 to the display unit 14 is not restricted.
- a suitable virtual image can be presented to the user E.
- the case where only the concave mirror 16 is arranged in the optical path between the transparent member 30 and the display unit 14 is shown.
- another optical element may be added between the display unit 14 and the concave mirror 16, and a folded mirror, a convex lens, or the like may be added.
- a convex lens is added between the display unit 14 and the concave mirror 16
- the reference position 20 of the display unit 14 is set so that the image display light after passing through the convex lens and reflected by the concave mirror 16 becomes parallel light.
