    • A holographic display device, e.g. for a vehicle, which reduces a color of hologram reflection toward the outside of the vehicle or a color of hologram transmission toward the inside of the vehicle generated at a hologram installation portion of a wind-proof glass, and which further reduces an external light noise. Light from a display element is transmitted through an imaging optical component to form a display image on a transmission diffusion hologram provided to a wind-proof glass, and the display image is reflected on the surface on the vehicle outer side of the wind-proof glass for visual recognition by an observer. The above transmission diffusion hologram is produced by diffused light, which is transmitted through a diffusion optical component, being made to fall on one side of a hologram photosensitive material.
