    摘要： The thermoplastic resin composition of the present invention comprises (A) a cycloolefin-based polymer and (B) a vinyl-based polymer having a polar group, has a glass transition temperature of not lower than 100° C. and has a difference in glass transition temperature between the polymers (A) and (B) of less than 50° C. The optical film of the present invention comprises the thermoplastic resin composition of the invention. According to the present invention, it is possible to improve development of retardation at a low stress in the film stretching while retaining excellent heat resistance and optical properties and maintaining wavelength dispersion properties. The optical film of the invention exhibits properties that the dependence of retardation of a transmitted light on wavelength, said retardation being obtained by stretch orientation of the film, becomes larger as the wavelength becomes longer (positive wavelength dispersion properties), has low water absorption and low coefficient of photoelasticity, and is excellent in adhesion or bonding properties to other materials.
