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. In the former case the hologram sheet is interposed between the PVB film and one of the glass plate and shielded from the PVB film by a transparent resin or glass film which prevents the plasticizer contained in the PVB film from transferring to the hologram sheet. In the latter case the hologram sheet is interposed between the two sheets of PBB film and shielded from each PVB film by a transparent resin or glass film having the aforementioned property. 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.
