Head-up display device

A laminated windshield incorporating a head up display device, comprising:

• an assembly of two transparent inorganic glass sheets connected together by an insert of a thermoformable material or by a multilayer leaf incorporating such an insert, in an order of:
• a first sheet, of which one face of the first sheet is turned towards the outside of the vehicle and the other face of the first sheet is in contact with the insert or multilayer leaf, the other face of the first sheet being in addition coated on at least one of its edges with a layer of an opaque, non-transparent material, or black material,
• a second sheet, of which one face of the second sheet is in contact with the insert or the multilayer leaf and the other face of the second sheet is turned towards the inside of the vehicle;
• and
• at least one layer of at least one luminophore material chosen to respond to an exciting incident light wave in the ultraviolet or IR region by re-emitting light radiation in the visible region, the layer being positioned on the windshield, at an angle of vision of a driver, in a region of the layer of the opaque, non-transparent, or black material, and the at least one layer is deposited in a form of a pictogram drawn in a characteristic sign marking vehicle instructions, information, or imminent danger, of the at least one luminophore material chosen to respond to the exciting incident light wave in the ultraviolet or IR region by re-emitting light radiation in the visible region.
