Abstract
Provided according to the present invention is a substrate for a flexible display device in which the problems of threshold voltage shift-induced current fluctuation and resultant image sticking can be solved by introducing an imide monomer as an organic filler into a polyamic acid composition to enhance thickness and surface direction densities in the film that is manufactured while vulcanization is performed at high temperatures, thereby enhancing thermal diffusivity and thermal conductivity of the film.
