Optical film for suppressing near infrared ray transmittance and display filter using the same

An optical film, comprising:

• a near-infrared absorbing layer, the near-infrared absorbing layer containing:
• at least one colorant having a maximum absorption wavelength in the range of 900 nm to 1,100 nm, and a transparent copolymer resin containing fine rubber particles, wherein:
• the copolymer resin has a total light transmittance of 90% or more and a haze of 2% or less, the copolymer resin includes a compound resin of one or more of an acrylonitrile butadiene styrene copolymer resin, a styrene butadiene styrene copolymer resin, and a styrene butadiene copolymer resin, a difference in refractive index between the fine rubber particles and a matrix resin of the copolymer resin is 0.01 or less, and the near-infrared absorbing layer has a transmittance of 30% or less, and a transmittance difference between a maximum transmittance and a minimum transmittance is lower than 20% in the wavelength range of 900 nm to 1,100 nm.
