PURPOSE: To secure a holographic display that gives no damage to the forward sight by preventing an observer from sighting any ghost.

CONSTITUTION: This holographic display is featured that a second reflection type hologram 13 whose incident angle out of light incident from the outside of a vehicle is θ1, and reflecting and diffracting the light of a wavelength area to be reflected and diffracted by a first hologram 3, toward the outside of the is set up at the more outside than this first reflection type hologram 3, and the light emitted toward the the first reflection type hologram 3 from a light emitting display means 1 is reflected and diffracted toward an observer 5 at a diffraction angle θ2 through the first reflection type hologram 3.
