Abstract: The invention relates to a laminated glass panel incorporating therein a hologram sheet. For example, the laminated glass panel is a vehicle windshield in which the hologram sheet is used as a combiner of a head-up display. As adhesive means, the laminated glass panel uses either one sheet or two sheets of polyvinyl butyral resin (PVB) film.

By virtue of the shielding of the hologram sheet from the PVB film, the diffraction wavelength of the hologram sheet does not significantly shift from the aimed wavelength.
