PROBLEM TO BE SOLVED: To provide a head-up display device capable of projecting a virtual image on a curved surface.SOLUTION: A head-up display device 100 includes: display means 5 that emits display light L showing an image; a pair of parallel flat mirrors 40 where the display light L emitted from the display means 5 enters and where a translucent plane mirror 41 that reflects a part of the display light L and transmits a part thereof and a plane mirror 42 that reflects the display light L toward the translucent plane mirror 41 are arranged in parallel; and a curved mirror 50 that reflects the display light L transmitted through the translucent plane mirror 41 to a curved surface so as to project an image shown by the display light L as a virtual image on the curved surface. The curved mirror 50 has a curved shape such that when display light L parallel to a first flat surface in the display light L transmitted through the translucent plane mirror 41 is reflected by the curved mirror 50 and the curved surface in this order, reflected display light L becomes display light L showing a virtual image parallel to a second flat surface. |
