Abstract:
An object of the present invention is to inexpensively manufacture a light-shielding film having excellent heat resistance and dimensional stability, having high light-shielding property and low glossiness and showing little variation in glossiness of the film. The present invention is to provide a light-shielding film containing a polyamide-imide resin, a black filler having average particle size of 0.01 to 1 μm and inorganic particles having average particle size of 0.1 to 10 μm, wherein content of the polyamide-imide resin is 55 to 91% by weight, content of the black filler is 1 to 10% by weight and content of the inorganic particles is 8 to 35% by weight in the light-shielding film.
