Abstract
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.
