摘要
The present invention relates to a polyamic acid and a display device, and more specifically to a display device including a polyamic acid and an imidized film thereof which can be used as a base layer or protective layer of the display device. Furthermore, the display device includes a polyamic acid and an imidized film formed therefrom which can be applied as the base layer or protective layer of the display device due to excellent thermal properties by a low thermal expansion rate and a high pyrolysis temperature.
