the second mirror reflects the projection light from the first mirror to the projection surface.
9. The display device according to claim 1 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
10. The display device according to claim 1 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
11. The display device according to claim 2 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
12. The display device according to claim 3 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
13. The display device according to claim 4 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
14. The display device according to claim 5 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
15. The display device according to claim 6 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
16. The display device according to claim 7 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
17. The display device according to claim 8 , wherein
the projection surface is positioned vertically below an eye point previously estimated, and
the holding unit holds the projector at the door body, in such a positional relationship that the projector projects the image to the projection surface from vertically below the projection surface.
