Abstract

The purpose of the present invention is to provide a head-up display device that enables a reduction in size. A head-up display device according to the present invention displays a virtual image by projecting display light onto a windshield. The head-up display device comprises: A display unit that radiates the display light; a second mirror having a reflective surface that reflects the display light toward the windshield; and a drive mechanism that rotates the second mirror among a plurality of rotation positions centered on an axis of rotation (Ax) such that the irradiation position of the display light on the windshield changes in the height direction. When the second mirror is at each rotation position, display light reflection regions for reflecting the display light on the reflective surface are set to be substantially the same.
