One of two images is selectively displayed on a single displaying screen of a display 11. The light of the displayed image is reflected from a mirror 13a and a half-mirror 13b toward a first reflective area 21a or second reflective area 21b of a translucent reflecting film 21 which is located in a field of view ahead of a driver's seat. An optical path is exchanged so that when the one image is displayed by the display, only the light of the one image reflected by the mirror 13a is incident on the first reflective area 21a, whereas when the other image is displayed by the display, only the light of the second image is incident on the second reflective area 21b. Two images are reflected from the translucent reflecting film 21 and visually recognized as a single virtual image ahead of a windshield 20 by a driver. In this configuration, a head-up display capable of displaying a larger image can be installed in a vehicle without being upsized.
