An infrared ray cutting film having a transparent base, a near infrared ray absorbing layer containing a compound of Formula (1) with a maximum absorption wavelength of from 750 nm to 920 nm, and a near infrared ray reflection layer obtained by fixing a cholesteric liquid crystal phase is excellent in invisibility, robustness and high heat shielding performance. R 1a and R 1b represent alkyl, aryl or heteroaryl; at least one of R 2 and R 3 is an electron-withdrawing group, and R 4 represents H, alkyl, aryl, heteroaryl, substituted boron, or a metal. |
