Abstract
A polyimide film includes a polyimide polymer forming a main molecular structure of the polyimide film, and polyimide particles present in the polyimide film at a weight ratio between about 15 wt % and 30 wt % of a total weight of the polyimide film, the polyimide particles having an average diameter between about 3 μm and 8 μm. The polyimide film can have a 60° gloss value equal to or smaller than 10, a haze equal to or higher than 90%, and a Young's modulus equal to or higher than 280 kgf/mm2. In some embodiments, methods of fabricating the polyimide film are also described.
