To provide a headup display device capable of displaying plural images easy to see and having a small and inexpensive constitution.

This headup display device is composed so that signal light beams 311, 312 radiated from a displayer 21 are projected on a combiner 11 provided with a reflection hologram, displayed images 821, 822 are visualized by the diffracted light beams 321, 322 reflected to the line of sight of an observer in the combiner 11. The displayer 21 has plural radiating surfaces 221, 222 radiating signal light beams 311, 312 in different wavelength bands and the hologram composing the combiner 11 makes the plural optical wavelength bands of signal beams the selected wavelength areas of high diffraction efficiency.
