Optical filter, and camera module and electronic device comprising the same

An optical filter, comprising

• a polymer film having a* of about −5.0 to about +5.0 and b* of about −5.0 to about +5.0, based on a color coordinate expressed by a CIE Lab color space;
• and
• a near infrared absorption layer on the polymer film, the near infrared absorption layer being configured to transmit light in a visible region and to selectively absorb at least one part of light in a near infrared region,
• the near infrared absorption layer including a first near infrared absorption material and a second near infrared absorption material,
• the first near infrared absorption material including a copper phosphate ester compound represented by Chemical Formula 4:
• wherein, in Chemical Formula 4,
• R41 and R42 are independently one of a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C2 to C20 alkenyl group, a substituted or unsubstituted C2 to C20 alkynyl group, or a substituted or unsubstituted C6 to C20 aryl group,
• n1 is an integer of 0 or 1, and
• n2 is an integer of 1 or 2,
• the second near infrared absorption material including at least two different organic dyes, and
• the second near infrared absorption material having a maximum absorption wavelength (λmax) in a wavelength region of about 650 nm to about 1200 nm.
