Abstract
An optical filter includes a polymer film and a near infrared absorbing layer on the polymer film, where the near infrared absorbing layer transmits light in a visible wavelength region and selectively absorbs at least a part of light in a near infrared wavelength region. An average light transmittance of the optical filter in a wavelength region of about 700 nanometers (nm) to about 740 nm is less than about 7%.
