A laminated motor-vehicle windshield includes two glass sheets that are joined together by an interlayer made of a thermoplastic of refractive index n1. The thermoplastic interlayer includes a cut-out section in the upper portion of the windshield. The cut-out section is filled with a multilayer film forming a waveguide for guiding waves from a bottom point of entrance of light radiation on the face of the windshield exposed to the exterior of the vehicle to a top point of exit of the radiation on the face of the windshield arranged toward the passenger compartment of the vehicle. The multilayer film includes layers of a first material of refractive index n2 such that n1≥n2 and of a second material that at least partially reflects the light radiation. The second material is placed on either side of the layer of first material to confine, in the latter, the light radiation.
