PROBLEM TO BE SOLVED: To provide a display device for a vehicle capable of displaying information of several kinds interlocking with the lighting of lights for a vehicle without obstructing a driver's visibility, and to provide a method of manufacturing a hologram film.SOLUTION: The display device 10 for a vehicle includes the hologram film 13 stuck on a window glass of an automobile, and a plurality of light sources 14, 15 which are arranged at a position that does not obstruct a driver's visibility in the cabin of the automobile and irradiate light to the hologram film. The display device is structured in such ways that each light source irradiates light at wavelength and/or an incidence angle different from each other to the hologram film and that the hologram film irradiates selectively in a predetermined direction the light of reproduction images of multiple display patterns 13a, 13b written in advance corresponding to the wavelength and/or incidence angle of the light from each light source. |
