Abstract
A glazing panel for a display device, includes an external first transparent pane and an internal second transparent pane, each pane including an external face and an internal face, the glass panes being joined together by an interlayer made of a thermoformable material or by a multilayer sheet incorporating such an interlayer; a protective layer made of an opaque material making contact with the internal face of the external first pane; a masking layer made of an opaque material making contact with the internal face of the internal second pane, the masking layer including apertures forming pictograms; and a uniform layer of a material doped with luminescent species chosen because they absorb light radiation produced by the source generating radiation in the UV or IR range, and re-emit light radiation in the visible range, the uniform layer being placed in the glazing panel, between the masking layer and the protective layer.
