Heads-up display device

A heads-up display device for projecting image light onto a transmissive reflective surface to cause a virtual image based on the image light to be visually recognized together with a real view through the transmissive reflective surface, comprising:

• a projection unit for emitting projection light forming a display image;
• a transmissive screen for orienting the image light obtained by transmitting and diffusing the projection light toward the transmissive reflective surface;
• and
• an optical axis adjustment unit for adjusting an angle of an optical axis of the projection light incident on the transmissive screen, the optical axis adjustment unit being arranged between the projection unit and the transmissive screen and including a first reflector for reflecting the projection light emitted by the projection unit, a second reflector for reflecting the projection light reflected by the first reflector, and an actuator for rotating the first reflector and the second reflector.
