    Abstract: Disclosed are a near-infrared absorbing film including a polymer film, a first near-infrared absorbing layer and a second near-infrared absorbing layer on the polymer film. The first near-infrared absorbing layer may be configured to transmit light in a visible region and to selectively absorb at least one part of light in a near-infrared region. The second near-infrared absorbing layer may be disposed on a surface of the first near-infrared absorbing layer. The first near-infrared absorbing layer may include a dye represented by Chemical Formula 1. The second near-infrared absorbing layer may include a copper complex compound. An optical filter may include the near-infrared absorbing film. An electronic device may include the optical filter. In Chemical Formula 1, R1 to R12 are described in the detailed description.
