Laminated glass and head-up display system

A laminated glass, comprising an inner glass plate, an outer glass plate and an interlayer film sandwiched therebetween, a side of the inner glass plate away from the interlayer film being provided with a first transparent nano-coating for reflecting P-polarized light, and the first transparent nano-coating comprising at least one stacked structure composed of a high-refractive-index material layer and a low-refractive-index material layer sequentially deposited outwards from a surface of the inner glass plate, wherein a second transparent nano-coating attached to the interlayer film is sandwiched between the inner glass plate and the outer glass plate, the second transparent nano-coating comprises dielectric layers and electrically conductive layers, and each of the electrically conductive layers is sandwiched between two of the dielectric layers;

• wherein the high-refractive-index material layer has a refractive index greater than or equal to 1.9, the low-refractive-index material layer has a refractive index less than or equal to 1.8, and the laminated glass has a P-polarized light reflectivity Rp greater than or equal to 16% at an incident angle of 65°.
