This window comprises a liquid crystal layer, and substrates that contain either an ultraviolet absorber or a colorant, the liquid crystal layer being arranged between two substrates which contain greater than or equal to 0.001 mass% of an ultraviolet absorbent or a colorant, wherein the transmittance of 1000 nm, polar angle 0° incident light at 0°C is greater than 70%, and the infrared light control film transmittance of 1000 nm, polar angle 0° incident light at 40°C is less than 60%. An infrared control film that satisfies the condition below has an infrared light transmittance that changes in accordance with the temperature, has good color in the front direction, and has high durability. 0.8 < a1 < 1.2; 0.8 < b1 < 1.2; a1 = (transmittance of 450 nm, polar angle 0° incident light) / (transmittance of 550 nm, polar angle 0° incident light); b1 = (transmittance of 550 nm, polar angle 0° incident light) / (transmittance of 700 nm, polar angle 0° incident light) ...
