Abstract (en)
[origin: WO2021080266A1] A transparent substrate with a multilayer thin film coating according to an example embodiment of the present invention includes a transparent substrate and a multilayer thin film coating, wherein the multilayer thin film coating includes a lower anti-reflection film, a lower metal protective layer, a metal functional layer having an infrared reflecting function, an upper metal protective layer, and an upper anti-reflection film sequentially stacked from the transparent substrate, each of the upper anti-reflection film and the lower anti-reflection film includes at least one dielectric layer, the upper anti-reflection film includes a silicon nitride-based dielectric layer, and the silicon nitride-based dielectric layer is stacked in direct contact with the upper metal protective layer and has a thickness of greater than or equal to 30 nm, a sum of the thickness of the lower metal protective layer and the upper metal protective layer is 0.6 nm to 2.25 nm, and a thickness of the lower metal protective layer is greater than that of the upper metal protective layer.
