Abstract
Provided is a polymer film which can eliminate both moire and glitter and is suitable for use as a diffusion film. The above-mentioned problems are solved with a polymer film, a surface of which has an arithmetic average roughness Ra of 0.63-1.80 μm, a root mean square roughness Rq of 0.76-2.40 μm, and an average height Rc of roughness-curve elements of 2.45-7.20 μm.
