Aerial image display device

An aerial image display device, comprising:

• a display including a display surface;
• a first concave mirror configured to reflect, in a direction different from a direction toward the display, image light emitted from the display surface;
• a convex mirror configured to reflect, in a direction different from a direction toward the first concave mirror, the image light reflected from the first concave mirror;
• a second concave mirror configured to reflect, in a direction different from a direction toward the convex mirror, the image light reflected from the convex mirror and form an aerial image as a real image from the image light;
• and
• a light shield between the display and the second concave mirror, the light shield being located off an optical path of the image light extending from the display surface to the aerial image through the first concave mirror, the convex mirror, and the second concave mirror,
• wherein the convex mirror is between the light shield and the second concave mirror.
