PROBLEM TO BE SOLVED: To provide a head-up display projecting display light onto a projection member, capable of suppressing the generation of a strain in an image even if the angle of a reflection member changes.SOLUTION: A head-up display comprises: an emission unit 41 emitting display light that is a light beam; a scanning unit 42 including a variable reflection surface and scanning the display light; an incident-angle change unit 43 changing an incident angle of the display light on the scanning unit 42 by integrally rotating the emission unit 41 and the scanning unit 42; a display unit 18 reflecting the display light from the scanning unit 42; a reflection member 15 magnifying and reflecting the display light from the display unit 18; an angle change unit 33 changing an incident angle of the display light on the reflection member 15 by rotating the reflection member 15 on the basis of an external indication; and a control unit 10 including a CPU and a memory, the display light being radiated among the emission unit 41, the scanning unit 42, the display unit 18, the reflection member 15, and a projection member so as to be substantially along a common plane, and the control unit 10 controlling the incident-angle change unit 43 to change the incident angle of the display light on the scanning unit 42 on the basis of the incident angle of the display light on the reflection member 15 and controlling the scanning unit 42 to cancel a strain of the display light generated by the reflection member 15. |
