Abstract: Provide a black matte polyimide film, including polyimide in an amount from 87 to 97 wt % of the black matte polyimide film, in which aromatic dianhydride and aromatic diamine are polymerized to form a polyimide precursor, and the polyimide precursor is chemically cyclized to form the polyimide, wherein the aromatic dianhydride at least includes 3,3′,4,4′-biphenyltetracarboxylic dianhydride in an amount being no less than 20 mol % of the aromatic dianhydride, and the aromatic diamine at least includes p-phenylenediamine in an amount from 5 to 40 mol % of the aromatic diamine; carbon black in an amount from 2 to 8 wt % of the black matte polyimide film; and silicon dioxide powder having a particle size between 1 and 10 μm and a density less than 1 g/cm3 and being in an amount from 1 to 5 wt % of the polyimide film.
