| titleOfInvention |
Polyimide precursor and polyimide film manufactured by using same |
| abstract |
The polyimide film prepared by using the polyimide precursor according to the present invention not only can improve optical properties such as YI and light transmittance, but also has little change in residual stress due to moisture absorption, Since it is possible to reduce the occurrence of cracks, it may be usefully used in manufacturing a flexible device. |
