Patent ID: 11204454

Abstract:
Embodiments relate to a layered film having an antireflection function and an infrared-shielding function. According to at least one embodiment, there is provided a layered film having a heat-ray shielding layer and a low-refractive-index layer in this order on at least one surface of a resin film, where the difference (Rh−Rf) of the refractive index (Rh) of the heat-ray shielding layer and the refractive index (Rf) of the resin film is −0.1 to 0.1, the difference (Rh−RL) of the refractive index (Rh) of the heat-ray shielding layer and the refractive index (RL) of the low-refractive-index layer is 0.05 or greater, and the refractive index (RL) of the low-refractive-index layer is 1.2 to 1.45. The thickness of the heat-ray shielding layer may be 0.1 to 5 μm. The visible-light transmittance of the layered film may be 88% or greater.
