Claim 10:
11. A movable body comprising:
a head-up display including
a display device which displays a first image and emits image light from the first image in a first direction,
a first optical member located in the first direction from the display device,
a second optical member located between the display device and the first optical member in the first direction,
a detector which detects positions of eyes of a user in the movable body,
an input part which is connected to the detector and receives inputs of positional information of detected positions of the eyes and a speed of the movable body driven by the user, and
a controller which is connected to the input part and changes, in accordance with the positional information, a position at which a virtual image of the first image appears,

the second optical member causing specular reflection of the first image in a first plane direction, causing retroreflection of the first image in a second plane direction, and displaying a virtual image of the first image in a space between the first optical member and the user,
the display device displaying a second image and emitting image light from the second image in the first direction,
the first optical member causing specular reflection of the second image and displaying a virtual image of the second image in a space opposite to, across the first optical member, the space in which the virtual image of the first image appears,
in response to a change in the speed, the controller not changing the position at which the virtual image of the first image appears and changing the position at which the virtual image of the second image appears.
