Abstract:
Provided are: an infrared control film in which an infrared light transmittance changes depending on the temperature, a tint in a front direction is excellent, and durability is excellent; and a window including the infrared control film. The infrared control film includes: a liquid crystal layer; and two substrates each of which includes at least one of an ultraviolet absorber or a colorant, in which the liquid crystal layer is disposed between the two substrates, the substrate includes 0.001 mass % or higher of the ultraviolet absorber or the colorant, a transmittance of the infrared control film at 0° C. with respect to an incidence ray at 1000 nm at a polar angle of 0° is higher than 70%, a transmittance of the infrared control film at 40° C. with respect to an incidence ray at 1000 nm at a polar angle of 0° is lower than 60%, and the following expressions are satisfied: 0.8
