Abstract
A display device includes: a display that generates image display light; a concave mirror that reflects the image display light such that the image display light is projected onto a transparent member; and a drive mechanism that moves the display in a range in which a distance from the concave mirror to the display is smaller than or equal to a reference distance at which the image display light traveling from the concave mirror to the transparent member becomes parallel light.
Claims3
A display device comprising:
- a display that generates image display light;
- a concave mirror that reflects the image display light such that the image display light is projected onto a transparent member;
- and
- a drive mechanism that moves the display in a range including a case where a distance from the concave mirror to the display is a reference distance at which the image display light traveling from the concave mirror to the transparent member becomes parallel light and a case where the distance from the concave mirror to the display is a distance shorter than the reference distance, wherein
- a) in a case where a front surface and a back surface of the transparent member are parallel to each other, the drive mechanism sets a distance from the concave mirror to the display to the reference distance, and
- b) in a case where the front surface and the back surface of the transparent member are not parallel the drive mechanism sets the distance from the concave mirror to the display to the reference distance or a distance shorter than the reference distance.
