A head-up display system of the present disclosure includes a display device that displays an image and a projection optical system that projects on the display member the image displayed on the display device. The projection optical system includes mirror MLthat reflects a light beam toward the display member and mirror ML-1that reflects the light beam toward mirror ML. Then, the projection optical system satisfies following condition (1):0.01LD is depth of mirror MLMLW is lateral dimension of mirror MLML-1Z is maximum sag amount of mirror ML-1ML-1W is lateral dimension of mirror ML-1.Such a configuration provides a head-up display system small in size that makes image distortion small in an entire viewpoint area of an observer.
