Abstract: In one aspect, a single layer polymer film includes 25 to 97.5 wt % of a polyimide having a refractive index of 1.74 or less, 0.5 to 20 wt % of a matting agent and 1 to 30 wt % of a black colorant. On an air side, the single layer polymer film has an L* color of 33 or less and a 60° gloss of 10 or less. In another aspect, a single layer polymer film includes 80 to 99 wt % of a polyimide having a refractive index of 1.74 or less and 1 to 30 wt % of a black colorant. A surface of the single layer polymer film has been textured and has a maximum roughness (Spv) of 7 μm or more, an L* of 33 or less and a 60° gloss of 10 or less.
