Abstract
The present invention provides a novel diamine compound capable of producing a polymer which exhibits greatly enhanced mechanical properties and heat resistance while maintaining transparency. A film including a polymer produced using the diamine compound has excellent transparency, heat resistance, mechanical strength and flexibility, and thus can be used in various fields, such as in a device substrate, a display cover substrate, an optical film, an Integrated circuit (IC) package, an adhesive film, a multi-layer flexible printed circuit (FPC), a tape, a touch panel and an optical disc protection film, and the like.
