A head-up display device includes a light source, a reflector, a reflector control unit, and a surface. The light source provides a light signal that corresponds to display data. The reflector is disposed rotatably in a first optical path of the light signal. The reflector control unit receives a control signal corresponding to the display data and controls rotation of the reflector about a rotational center. The surface is disposed in a second optical path. When the reflector is rotated for a predetermined rotational angle by the reflector control unit according to the control signal, the light signal reflected by the reflector is projected on the surface to display an image corresponding to the display data on a predetermined region of the surface.
