A head-up display device includes an image display device that outputs display light of an image; a mirror having a reflecting surface that reflects the display light toward a reflecting portion, and an input shaft; a motor that has an output shaft located on an extended line of the input shaft, and rotates the output shaft; a transmission member that has a cylindrical fitting portion to which the input shaft is press-fitted and a coupling portion coupled with the output shaft and transmitting output torque of the motor from the output shaft to the input shaft; a holding member that holds the motor; and a first spring that is interposed between the holding member and the transmission member, and imparts, to the transmission member, a biasing force oriented to bring the mirror close to the output shaft.

A backlight unit includes a housing having an opening in which an liquid crystal display device is disposed, a light source disposed inside the housing, and an optical member disposed inside the housing, turning a path of light from the light source toward the liquid crystal display device, and having a triangular prism portion made of a translucent material. The prism portion has one side wall serving as an entrance wall on which the light from the light source is incident, another side wall as an exit wall emitting light to the liquid crystal display device, and still another side wall as a reflecting wall reflecting the light incident on the entrance wall to the exit wall inside the prism portion.
