PROBLEM TO BE SOLVED: To provide a simple head-up display device capable of displaying a far-range image and a near-range image. SOLUTION: A head-up display device 10 comprises a far-range image forming light projector 40, a near-range image forming light projector 42, and a half mirror 44. The far-range image forming light projector 40 is installed on a cabin ceiling. By reflecting the far-range image forming light 39 to a combiner 50 side by the half mirror 44, the distance from the far-range image forming light 39 to an eye-point 52 of a driver is increased. Further, the near-range image forming light projector 42 is installed in a vicinity of the half mirror 44, and the near-range image forming light 41 transmits a part for reflecting the far-range image forming light 39 of the half mirror 44. Thus, a far-range image 54 and a near-range image 55 can be displayed on the same area in the field of front vision of the driver 15. COPYRIGHT: (C)2009,JPO&INPIT
