    摘要: An optical film includes a polarizer, a uniaxially elongated film disposed on the polarizer, and a compensation film disposed on one side of the uniaxially elongated film. The polarizer includes a polymer having a glass transition temperature of greater than about 100° C. and including a structural unit derived from styrene or a styrene derivative. The compensation film has a refractive index satisfying Relationship Equations 1 and 2, the uniaxially elongated film has an in-plane retardation satisfying Relationship Equation 3 and a thickness retardation satisfying Relationship Equation 4, and the compensation film has an in-plane retardation satisfying Relationship Equation 5 and a thickness retardation satisfying Relationship Equation 6. A liquid crystal display including the optical film is also disclosed. Relationship Equations 1 to 6 are described in the detailed description.

    摘要: 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.
