Diamine compound, and polyimide precursor, polyimide film and flexible device prepared by using the same |
| abstract |
The present invention provides a novel diamine compound ncomprising a structure that a diphenyl sulfide is bonded via an amide to a phenyl ring substituted with an amine group in the molecule thereof, and the diamine compound is used to prepare a polyimide film having improved thermal properties and storage stability as well as improved refractive index. The present invention also provides a polyimide precursor and a flexible device prepared by the diamine compound. |
