Abstract: The present invention relates to a polyamic acid solution and a display device, and more specifically, to a polyamic acid solution which can be used for a base layer or a protective layer of a display device, and a display device including a film formed by the imidization of the polyamic acid solution. The polyamic acid solution has excellent thermal characteristics such as a low coefficient of thermal expansion and a high thermal decomposition temperature, and can thus be applied to a base layer or a protective layer of a display device.
