vehicle, the projector includes a reflection unit configured to reflect projection light representing the image to the projection surface, and the holding unit holds the projector at the door body, in such a positional relationship that at least part of the reflection unit is positioned on the vehicle interior side relative to a surface provided with the projection surface, in the door body. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the reflection unit includes a magnifying mirror configured to enlarge and reflect the image represented by the projection light. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the reflection unit includes a free curved surface mirror configured to correct distortion of the image represented by the projection light and reflect the image. ### Claim 4 (depends on 2) The display device according to claim 2, wherein the reflection unit includes a free curved surface mirror configured to correct distortion of the image represented by the projection light and reflect the image. ### Claim 5 (depends on 1) The display device according to claim 1, wherein the reflection unit includes a first mirror and a second mirror, the first mirror reflects the projection light representing the image to the second mirror, and the second mirror reflects the projection light from the first mirror

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. ### Claim 15 (depends on 6) 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. ### Claim 16 (depends on 7) 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. ### Claim 17 (depends on 8) 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. ### Claim 18 A vehicle door comprising: a door body provided at a vehicle; a projection surface provided on a surface on a vehicle interior side of the door body; a projector configured to project an image; and a holding unit configured to hold the projector at the door body, in such a positional relationship that the image from the projector is projected on the projection surface, wherein the projected image can be recognized by a driver of the vehicle or another occupant of the vehicle, 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. ### Claim 19 A display device comprising: a projection surface provided on a surface on a vehicle interior side of a door body provided at a vehicle; a projector configured to project an image; and a holding unit configured to hold the projector at the door body, in such a positional relationship that the image from the projector is projected on the projection surface,
