CYCLIC OLEFIN RESIN COMPOSITION FILM

摘要

Provided is a cyclic olefin resin composition film which has a low linear thermal expansion coefficient, while having excellent optical characteristics and excellent toughness. This cyclic olefin resin composition film contains a cyclic olefin resin (11), a styrene elastomer (12) and inorganic oxide fine particles (13), and has a linear thermal expansion coefficient of from 40 ppm/°C to 60 ppm/°C (inclusive). Consequently, this cyclic olefin resin composition film is able to achieve excellent optical characteristics and toughness, while maintaining a low linear thermal expansion coefficient.
